Try this (untested and unparsed, minor changes maybe necessary :)

string whatever = "foo";
system(foo.c_str());

I may be wrong here, and if so feel free to slap me, but I think that ought
to be

#include <cstdio>
#include <cstring>
#include <cstdlib>

and your own header files should be included as

#include "myheader.h"

See the end of http://www.comeaucomputing.com/techtalk/#cname.  I quote:
-->
Similarly, the Standard C headers, such as <stdio.h>, are supported in C++,
but they are deprecated. Instead, so-called Cname headers are preferred, for
instance, cstdio, or cctype instead of ctype.h Furthermore, names in the .h
are assumed to be in the global namespace, and so therefore do not need to
be qualified with std::. The .h form is sometimes used as a transition model
for backwards compatibility. Or, for a "co-ed" source file able to be
compiled by a C or C++ compiler.

Hi *,

Simon, you can both use a char array (buffer) from the beginning or use
string and then copy the contents to a char array (buffer), anyway this i=
s a
mixed C/C++ situation:

1st)=20
#include <iostream>=20
#include <stdlib.h>

#define BUFFER_SIZE	32

int main()
{=20
char 	 szIP[BUFFER_SIZE];
char 	 szCommand[BUFFER_SIZE];

cout << "Enter the ip to trace:";
cin >> szIP; //enter domain-name of pc

sprintf(szCommand,"tracert %s",szIP);

system(szCommand);
system("PAUSE");
return 0;=20
}=20


Or the 2nd option)

#include <iostream>=20
#include <string>
#include <stdlib.h>

#define BUFFER_SIZE	32

char*	ConvertStringToSzData(string strValue)=20
{
=09int  iStrLen =3D strValue.size();
=09char* pSzData =3D (char*) malloc( (iStrLen+1)*sizeof(char) );

=09if (pSzData)
=09{
=09	strncpy(pSzData,strValue.data(),iStrLen);
=09	// NULL TERMINATED STRING ;o)
=09	pSzData[iStrLen] =3D '\0';
=09}

=09return pSzData;
}

int main()
{=20
string strIP;
char 	 szCommand[BUFFER_SIZE];

char* pSzIP =3D NULL;

cout << "Enter the ip to trace:";
cin >> strIP; //enter domain-name of pc

pSzIP =3D ConvertStringToSzData(strIP);

if (pSzIP)
{
=09sprintf(szCommand,"tracert %s",pSzIP);

=09free(pSzIP);

=09system(szCommand);
}
else
=09cout << "ERROR: Cannot convert string to char array!" << endl;

system("PAUSE");
return 0;=20
}=20

Hope this helps!

Hello everybody,

[Dev-C++] linker/unresolved external <- recap/thanks

[The Tone's. <to...@ds...>]

all,

to those that responded, thanks.

Now that I understand the distinction between the GNU libc and the GNU GCC
suite, a few things have clarified.

I am working on a console app that will be parsing through several ASCII text
files, of differing format, where the "records" in these files can vary on a
line by line basis. according to a handful of rules.

The format is not under my control.

Can anyone recommend a nice, tight, chunk of code written in 'C' that will make
my life easier for reading strings from files, pattern matching and string
manipulation ?

TIA,
Tony

AW: [Dev-C++] execution of a string with system()

[Christian W. <Chr...@vo...>]

Hi Simon,


I have done it this way:

#include "stdio.h"
#include "string.h"
#include "stdlib.h"



int main(int argc, char* argv[])
{
	char szShellCmd[200];
	strnset(szShellCmd, 0, sizeof(szShellCmd));


	strcpy(szShellCmd, "dir *.*\0");

	system(szShellCmd);

	getchar();

	return 0;
};

and it works.

I have the cpluplus reference, and by it and the name fgets is for workin=

Ouch! I had the feeling of forgetting something.
buffer[size] =3D '\0';
It shouldn't run out of buffer, the parameter is given. (well, size =3D l=
ast non \0 index
+1)

(I didn't test it)

Forst of all, I didn't know that overload existed in C.

Second. Why write a new getline with - almost - the same function as
the already existing fgets?

Third. The sample code never terminates the loaded buffer after it finds z
newline character, or runs out of buffer space.

RE: [Dev-C++] Newbie Needs Help

[Santiago P. C. <San...@yd...>]

Hi John,

Please take a closer look to:
- function calling mechanism and return Values,
- variables scopes,
- passing variables by reference or by value,

In your code you are...

1st) ...Passing variables by value _NOT_BY_REFERENCE_ so you cannot modif=
y
its value inside the function you are passing the variable to.

=09int FirstNumber(int NumberOne)
=09{
=09	cout << "Enter how much money you had this morning $";
=09	cin >> NumberOne;		// <=3D this NumberOne is NOT
the same as main's NumberOne
=09}

2nd) ..."Mixing" the way a variable is defined and the way that variable'=
s
content is handled.

=09int ThirdNumber(int NumberThree)
=09{
=09  // NumberThree =3D int NumberOne - int NumberTwo;	// <=3D WRONG
STATEMENT
=09  //		you are "trying to define" 'NumberOne' and
'NumberTwo' erroneously and in a local scope,
=09  // 		please have in mind that you are not referencing
main's 'NumberOne' and 'NumberTwo'

=09  cout << "You have spent $" << NumberThree << " dollars today " <<
endl;
=09}

3rd) ...defining functions to return an int value but not returning it:

=09int FirstNumber(int NumberOne)
=09{
=09	cout << "Enter how much money you had this morning $";
=09	cin >> NumberOne;		// <=3D this NumberOne is NOT
the same as main's NumberOne

=09	// There must be a return statement here!!!!
=09}

4th) ..."thinking" that you are calling functions while you're NOT doing
that...

// Main Function
int main(int argc, char *argv[])
{
=20   int NumberOne;
=20   int NumberTwo;
=20   int NumberThree;

=09//  Here you are "trying to REdefine" the functions, NOT calling
them
=20   int FirstNumber(int NumberOne);	=09
=20   int SecondNumber(int NumberTwo);
=20   int ThirdNumber(int NumberThree);

=20   system("PAUSE");
=20   return 0;
}

There are also some "design issues" that I think you should take a look a=
t;
so I've modified your code the way I think it should look like (I've
modified some names in order to clarify the code ;oD):

#include <iostream>
#include <string>

/*
This program in designed to take input from the user,
in the form of a number and compute the output.
The program is then to display the output back to the user.
*/

// Function Definitions
int GetFirstNumber();  =20
int GetSecondNumber(); =20
void ShowThirdNumber(int iNumberOne, int iNumberTwo);

// GetFirstNumber Function
// The function gets an input from the user and returns it
int GetFirstNumber()
{
=20 int iLocalNumberOne =3D 0;
=20 cout << "Enter how much money you had this morning:" << endl ;
=20 cin >> iLocalNumberOne;

=20 return iLocalNumberOne;
}

// GetSecondNumber Function
// The function gets an input from the user and returns it
int GetSecondNumber()
{
=20 int iLocalNumberTwo =3D 0;
=20 cout << "Enter how much money you have now:" << endl;
=20 cin >> iLocalNumberTwo;

=20return iLocalNumberTwo;
}

// ShowThirdNumber Function
void ShowThirdNumber(int iNumberOne, int iNumberTwo)
{
=20 int iLocalNumberThree =3D iNumberOne - iNumberTwo;
=20 cout << "You have spent " << iLocalNumberThree << " dollars today " <=
<
endl;
}

// Main Function
int main(int argc, char *argv[])
{
=09// Retrieve first Number by calling the appropriate function and
=09// store it at int variable called 'iTheFirstNumber'
=09int iTheFirstNumber =3D GetFirstNumber();

=09// Retrieve second Number by calling the appropriate function and
=09// store it at int variable called 'iTheSecondNumber'
=09int iTheSecondNumber =3D GetSecondNumber();

=09// Call the apropriate function with the previously acquired values
=09// in order to print the result to the screen
=09ShowThirdNumber(iTheFirstNumber, iTheSecondNumber);

=20   system("PAUSE");
=20   return 0;
}

Hope this helps!!!

[Dev-C++] Re: auto-indent

[Gaetan K. <gk...@et...>]

>>   Hi, how does auto-indent work?
 
>It works fine here under v 4.9.4.1
 
I'm using 4.9.5.3

RE: [Dev-C++] Newbie Needs Help

[Ramana K. <ra...@my...>]

You do not use the type "int" when you are using the - operator:

	NumberThree = int NumberOne - int NumberTwo;

is wrong syntax.
you need instead:

	NumberThree = NumberOne - NumberTwo;

but for this to work, the function ThirdNumber(int) needs to take NumberOne
and NumberTwo as parameters.
so you need to put

	ThirdNumber(int,int,int);

as the definition. and in the main function, you call it like this:

	ThirdNumber(NumberThree,NumberTwo,NumberOne);

you do not call functions with their return type and argument types either:

	int FirstNumber(int NumberOne);

is wrong syntax (this is the call, not the definition).
you need instead:

	FirstNumber(NumberOne);

you also need to use references, because the data you get from the user does
not survive the local scope of the function.
maybe i just write out your program correctly, removing syntax errors (but
not improving code):

#include <stdio.h>
#include <iostream>
#include <string>

/*
This program in designed to take input from the user,
in the form of a number and compute the output.
The program is then to display the output back to the user.

The compiler doesn't know what to do with this code gathering two declarations of int vars 
minusing themselves at the same time. Remove that line.

Remember that NumberOne and NumberTwo are not global vars so they are not known inside 
the ThirdNumber function. Only in the main section, where they are declared. By the way, 
remove the int return values of each function since they don't do anything but asking for a user 
input.

All you have to do in the main section is :

ThirdNumber(NumberTwo-NumberOne);

And in the ThirdNumber func :

void  ThirdNumber(int NumberThree)
{
     cout << "You have spent $" << NumberThree << " dollars today " << endl;
 }

Kind regards

Gudday All,

    I have a small problem which I cant seem to find the answer to. I was
hoping that someone could help. I am just beginning to learn c++, so the
code is not to complex. My problem lies in the compilation process. I am
unsure as to how to fix the compilation error.

Thanks to everybody.
Have a good one.
John

Here is the compilation error.

Re: [Dev-C++] unresolved external/linker error

[Carlos d. M. <cg...@wo...>]

Oh, yes, iostream is C++, I should have notice it, stdio has no getline.
There are no C getline(), only C++, the one from iostream and the other w=
hich come
=66rom string and the other string classes. And get is either from iostre=
am.

You can make your own getline, overload it
void getline(char *buffer, int size){
char test =3D 'a';
for (int i =3D 0; i < size && test !=3D '\n'; i++){
buffer[i] =3D get();
test =3D buffer[i];
}
}

[Dev-C++] auto-indent

[Gaetan K. <gk...@et...>]

Hi, how does auto-indent work? I marked the checkbox but it doesn't do
anything.
(shouldn't it indent a line after I press ENTER?)
 
thanx

Re: [Dev-C++] unresolved external/linker error

[Per W. <pw...@ia...>]

You can still use fgets. It's just the gets that must not be used, since
it doesn't take the size of the input buffer as a parameter.

Re: [Dev-C++] unresolved external/linker error

[The Tone's. <to...@ds...>]

uhh ...

I think I get it now.

These functions are actually part of the "GNU libc" ... not part of the GNU
compiler suite and any runtime libs it contains ?

so ... I would need to have this stuff, and it looks like the source is not
portable to windows ?

Re: [Dev-C++] unresolved external/linker error

[The Tone's. <to...@ds...>]

To recap :

I was trying to use the "getline()" function in the GCC/GNU distro as included
in Dev-Cpp v5 beta.

I was getting an error from the linker.

I looked into the <iostream.h>.

This appears to be a C++ header.

I am developing/compiling as 'C'.

I tried it anyway.

compile errors. to be expected.

The GCC docs seem to imply that this is a <stdio.h> function that can be used
from 'C' code ?

???

Tony

Re: [Dev-C++] executable size

[Per W. <pw...@ia...>]

When compiling with debug information on, every new include file results
in larger executable. windows.h isn't any include file. It is THE include
file. It continues to include a lot of other windows files.

[Dev-C++] executable size

[The Tone's. <to...@ds...>]

hi,

noob here again.

I notice that simply doing a #include <windows.h> increases my executable size
by some 250k without touching any functions in my code within WIN32.

Again, I am a Java programmer, so I am trying to get my head around how this
stuff works.

Is this increase in size due to needing a larger 'text' segment for all of the
stuff defined in <windows.h> and the 5 zillion #includes it pulls in ?

Or ... is this because libs or something are getting statically linked into the
executable ?

TIA,
Tony

RE: [Dev-C++] unresolved external/linker error

[The Tone's. <to...@ds...>]

yeah.

this is what the doc for GCC said, thus my attempt to use the alternative
getline().

somebody else suggested #include <iostream.h>.

I'll try this.

The GCC doc said that this function was part of <stdio.h>.

Cheers,
Tony

[Dev-C++] re: directx

[Daniel G. <sp...@ho...>]

There was somebody who had a site hosting the libraries (those .a files) 
that you need to run directX 8 HOWEVER I found I could only run very VERY 
basic apps (like the first 2 samples that come with the SDK) using the 
previous version of DEV and had to buy Visual C++ 6.0 in order to get 
anything else working. I needed it as I was trying to get  a programming 
job, which did help me in the end but not with video game companies - unless 
you have tons of experience (as with most jobs, especially programming) 
you're not getting in. And recruitment agencies mislead you, or just don't 
know the first thing about getting programming jobs.

Ugh, I hate recruiters.


P.S. I've had probs sending this email to the list.
