c++ beginning with codeblocks

[cfrank]

I've just installed codeblocks and I tried to build my first c++ program just to display two words. as a result I've got: fatal error: no such file or directory.
can I get help to fix this problem.

Well, post some code.

Look up a tutorial on basics of c++. Or use this site itself.
But a basic program to print stuff:

#include<iostream>

using namespace std;

void main()
{
    cout << " Your text here ";
    cin.ignore();
}

@ASI7296 Although it will work, main() should always return an int. When you do int main(), it will automatically return 0, or you can type return 0; out yourself.

[LzwkoG1T]

that's only necessary on some compilers right? not on all (I think.)

[jwkNwA7f]

@ASI729g I don't know much about why it is not a good idea. I have heatd it said by a lot people. It should still work on most compilers

It is bad because the C++ Standard (the "contract" by which all C++ compilers must conform) says that main must return an int. Stroustrup's FAQ:

Thank you for the info :)

[Daleth]

void main() is acceptable in C, I believe.

void main() is acceptable in C, I believe.

I again refer to Stroustrup's FAQ:

http://www.stroustrup.com/bs_faq2.html#void-main

The definition

void main() { /* ... */ }

is not and never has been C++, nor has it even been C. See the ISO C++ standard 3.6.1[2] or the ISO C standard 5.1.2.2.1.

Oh, I must have been working off outdated information. I learned that the implementation may allow the syntax void main(), but it still returns an int somehow.

[Dy7SLyTq]

no i dont think void main returns an int. it is not allowed in c/c++ by the standard but certain compilers (it might be all... i havent tested it) allow you to return nothing. its frowned upon, but it will "work"

[Daleth]

I meant like I read somewhere that the C standard allows the void syntax as long as the compilers still have main() return an int. I wish I could find that page.

[Dy7SLyTq]

that doesnt make any sense. c does not allow void at all by the standard. and if you have void main it wont return an int, once again that wouldnt make any sense

[S G H]

For safety's sake, just return an int :D
