RT: Testing: A Simple Hello World Program

[Nobody/Anonymous]

yes, system("pause") will work under DOS only, indeed it is a legacy DOS function that was frequently used in batch files.
However, please note that you cannot create DOS executable with DevCPP/MingW32.

Mike,

The pause also works under Windows XP for example, in which there is NO DOS. At all.

I am using Dev-C++ 4.9.8.9

my code

include<iostream>

include<stdlib.h> //only needed if you are using Dev 4 family

using namespace std; //where the names are - like cout!

int main(void)
{
cout << "This is what that putz Wayne said to do!\n";
system("pause"); //keep the window open if running from Dev
return 0;
}

(The same as the first one i wanted to test it.)

I cant see my compile log because it comes up then leaves quickly automatically (like less than half a second...anyone know a reason why??) Then at the bottom it says unable to run program file. Soo.. if i go to Execute Run it says Source file not compiled. Help would be appreciated thanks.

[Nobody/Anonymous]

The log is on the tab labeled "Compile Log", it does not come up and leave.

Please start a new thread with your question, remembering to post your "Basic 3"

Wayne

p.s. Are you sure it is 4.9.8.9?

[Nobody/Anonymous]

yeah it says 4.9.8.9 in the top left corner.

[Nobody/Anonymous]

That version has got the be a year or more old, I would recommend doing a clean uninstall (see directions in the thread PLEASE READ BEFORE ASKING A QUESTION) on how to do that.

And please start a new thread if you are still having issues...

Ok guys i just installed 4.9.7.0 from the C++ dummies guide. So of course it does not compile properly becuase i quess its not a full install.

which version do i download now to get this bady up and running.

1. My Dev-c++ version is 4.9.9.2

2. include<istream>

include<stdlib.h>

using namespace std;

int main(void)
{
cout << "Hello World!\n";
system("paus")
return 0;
}

1. make.exe -f "C:\Documents and Settings\Jimmie\Skrivbord\Scripts\Prov1\Makefile.win" all
   g++.exe -c main.cpp -o main.o -I"C:/Dev-Cpp/lib/gcc/mingw32/3.4.2/include" -I"C:/Dev-Cpp/include/c++/3.4.2/backward" -I"C:/Dev-Cpp/include/c++/3.4.2/mingw32" -I"C:/Dev-Cpp/include/c++/3.4.2" -I"C:/Dev-Cpp/include"

main.cpp: In function int main()': main.cpp:8: error:cout' undeclared (first use this function)
main.cpp:8: error: (Each undeclared identifier is reported only once for each function it appears in.)
main.cpp:10: error: expected `;' before "return"

make.exe: *** [main.o] Error 1

1. My problem is that when i'm trying to start the program.. nothing happens, Not an singel window popps up.. I have try 3 diffrent codes and still nothing..!

[Osito]

You have a lot of typos. The one causing cout not to be found is that it's called iostream not istream.

[Nonamer]

I fixed it.. but it's still one error with: "Return 0;"

make.exe -f "C:\Documents and Settings\Jimmie\Skrivbord\Scripts\Prov1\Makefile.win" all
g++.exe -c main.cpp -o main.o -I"C:/Dev-Cpp/lib/gcc/mingw32/3.4.2/include" -I"C:/Dev-Cpp/include/c++/3.4.2/backward" -I"C:/Dev-Cpp/include/c++/3.4.2/mingw32" -I"C:/Dev-Cpp/include/c++/3.4.2" -I"C:/Dev-Cpp/include"

main.cpp: In function int main()': main.cpp:8: error:cout' undeclared (first use this function)
main.cpp:8: error: (Each undeclared identifier is reported only once for each function it appears in.)
main.cpp:10: error: expected `;' before "return"

make.exe: *** [main.o] Error 1

[Osito]

Actually it still says you have the same error. Are you sure you fixed the iostream typo?

[Nonamer]

This is the code now:

include<iostream>

include<stdlib.h>

using namespace std;

int main(void)
{
cout << "Hello World!\n";
system("paus")
return 0;
}

[Osito]

That log you posted isn't from the code you posted. But your next typo is the missing semicolon right before return 0;

Any time it gives you a line number of an error, you should start by also checking the line before it. A lot of times a missing semicolon, bracket, close parentheses, etc, on one line can cause the error to appear to be on the following line.

[Nonamer]

Btw, sorry for dubbel posting, but heres another one: 10 C:\Documents and Settings\Jimmie\Skrivbord\Scripts\Prov1\main.cpp expected ;' before "return" C:\Documents and Settings\Jimmie\Skrivbord\Scripts\Prov1\main.cpp In functionint main()':

(srry im swedish)

[Nonamer]

Ok anoying, still an ERROR..

include<iostream>

include<stdlib.h>

using namespace std;

int main(void)
{
cout << "Hello World!\n";
system("paus")
;return 0;
}

make.exe -f "C:\Documents and Settings\Jimmie\Skrivbord\Scripts\Prov1\Makefile.win" all
g++.exe -c Namnlös1.cpp -o Namnlös1.o -I"C:/Dev-Cpp/lib/gcc/mingw32/3.4.2/include" -I"C:/Dev-Cpp/include/c++/3.4.2/backward" -I"C:/Dev-Cpp/include/c++/3.4.2/mingw32" -I"C:/Dev-Cpp/include/c++/3.4.2" -I"C:/Dev-Cpp/include"

g++.exe: Namnl÷s1.cpp: No such file or directory
g++.exe: no input files

make.exe: *** [Namnlös1.o] Error 1

Is it me who alwayse get it wrong? becus i got the first code from: "Accelerated C++ 2000"

and there the code is:

include <iostream>

int main()
{
std::cout << "Hello, world!" << std::endl;
return 0;
}

[Osito]

That last error looks like it didn't recognize the character in the filename:

g++.exe: Namnl÷s1.cpp: No such file or directory

Was it originally called main.cpp? Because you didn't have that error when you started.

[Nonamer]

Yea! worked! but now it's the window xD just show one sec and then it's quits :/ By the way, thanks so mutch all for your help!

[Osito]

The window closes because you have paus instead of pause in your system command.

[Nonamer]

Haha =P it worked but it did not say "Hello World" It's says "press any key to continu"

[Wayne Keen]

Odds are you compiled your code as windows project, and not a console project.

Please start a new thread, and post your Basic 3 there.

[Osito]

You're saying this code doesn't print Hello World?

include<iostream>

include<stdlib.h>

using namespace std;

int main(void)
{
cout << "Hello World!\n";
system("pause")
;return 0;
}

[Nathaniel]

Os is Windows Vista, I'm running Dev-C++ 4.9.9.2

include <cstdlib>

include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
cout << "Hello, this is your computer speaking." << end1;
system("PAUSE");
return EXIT_SUCCESS;
}

In function int main(int, char**)':end1' undeclared (first use this function)
(Each undeclared identifier is reported only once for each function it appears in.)

Seems as though I'm have a bit of trouble with the "end1" clause.

Any help would be much appreciated!
Thanks
Nathaniel.

[Nathaniel]

Please ignore my last question, (wow I feel so dumb --...) Anyways I thought this whole time it was end1 and not endl --.... sorry for being ignorant and wasting time and thread =).
