[Danny A. <tam...@ms...>]

HEY GUYS,

I'm that newbie guy that keeps having trouble.  I got a book "C++ for the=
 absolute beginner," well this beginner doesn't still get it.  So I'm won=
dering if you can explain what the book is failing to explain.  Below is =
a program I typed in, that is giving me fits over "enum" and all its "ret=
urns" I feel like I missing something in my lib.'s but I'm not sure.  I h=
ave double checked everything several times to the book and from all that=
 I can see I have typed it out just as the book has it.  I take it though=
 one complier will do things differently than another and I know the auth=
or is using a different complier.  So if anyone can help me I'm all ears.=

THANKS DANNY!!

the following code works, check it against the lines you posted. If you 
have questions, let us know.

#include <iomanip>

// all ANSI C++ programs require a "main" function.
int
main()
{
         float number1; // first number
         float number2; // second number

         std::cout << "Enter 2 floating point numbers" << std::endl;
         std::cin >> number1 >> number2; // one instruction reads both

         // remember that some settings are active until you change them,
         // the precision and the way real numbers are displayed are an
         // example.

         std::cout << "The floating point numbers are:\n"
                   << std::setprecision(2)
                   << std::setiosflags(std::ios::fixed | std::ios::showpoint)

Hey guys

I'm still very green at this and I just inputted a small program (listed =
below) from "Teach Yourself C++",  and when I try to compile it gives me =
errors

You mispelled the statement, the firt semicolon is a comma (,) so you
have a first field with two assigments, the second with a condition and
the third with the operation.

Hey guys;
this newbie is back at it again trying to figure out what I'm doing below=
 is a very long piece of code in 5 different files that I'm trying to com=
pile in one project but for some reason even though I have typed it out o=
f a book and I have played with it and I have even gone to the authors so=
urce code and copied and paste from them and it still doesn't want to wor=
k.  I'm beginning to believe it could be a difference in compilers the au=
thors used "CodeWarrior" and the book I'm using is "C++ Programming for t=
he absolute beginner". if anyone can be of help I would appreciate it bec=
ause it would truly teach me something I can't figure out.

Thanks in advance

RES: [Dev-C++] errors

[Daniel K. O. <dan...@ya...>]

Try putting your includes like this:

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



And I noticed the identifiers you're using in the enum type:

	enum SquareState { blank = ' ' , X =  'X', 0= '0' };

Look: you're using 0 (zero) instead O (letter). Identifiers shouldn't start
with a digit, like 0 (zero).
The same where you're returning zero instead O.


Hope this can help you.

HEY GUYS,

I'm that newbie guy that keeps having trouble.  I got a book "C++ for the
absolute beginner," well this beginner doesn't still get it.  So I'm
wondering if you can explain what the book is failing to explain.  Below is
a program I typed in, that is giving me fits over "enum" and all its
"returns" I feel like I missing something in my lib.'s but I'm not sure.  I
have double checked everything several times to the book and from all that I
can see I have typed it out just as the book has it.  I take it though one
complier will do things differently than another and I know the author is
using a different complier.  So if anyone can help me I'm all ears.

THANKS DANNY!!

This is a mistake. The proper ANSI C++ header style is #include
<iostream> . iostream.h e.t.c is illegal, in all modern compilers is
depricated and is about to removed from future versions.

Re: [Dev-C++] errors

[Jason H. <jas...@bt...>]

The errors you are getting are all due to simple typing errors. If you =
look in the enum you have substituted the number 0 with the letter O, =
notice the subtle difference in width between letter and number. So =
where you have previously put zero you need to put the letter O, but =
only for the lines dealing with the enumeration, and returning an =
enumeration type. Another mistype you have is where a ) bracket has been =
substituted for a } brace.

If you go through the errors double clicking the top one and correct the =
error, and then recompiling eventualy you will get a full compile. =
However I suggest you look at the code as the game doesn't apear to work =
properly, so there may be other more subtle erros, maybe mistyped =
numbers etc...

Jason.

HEY GUYS,
 
I'm that newbie guy that keeps having trouble.  I got a book "C++ for
the absolute beginner," well this beginner doesn't still get it.  So I'm
wondering if you can explain what the book is failing to explain.  Below
is a program I typed in, that is giving me fits over "enum" and all its
"returns" I feel like I missing something in my lib.'s but I'm not sure.
I have double checked everything several times to the book and from all

though one complier will do things differently than another and I know
the author is using a different complier.  So if anyone can help me I'm

enums are user defined discrete integer types.
