    New Compiler

    I just got Bloodshed Dev-C++, and I'm having a couple of problems, I write the code and get no errors, but when I execute the file, nothing happens...

    Here is the code:

    Code:
    #include <iostream>
    #include <conio.h>
    using namespace std;
    
    int main()
    {
        cout << "I like pants!" << endl;
        getch();
        return 0;
    }
    So any advice, suggestions, comments?

    What do you mean nothing happens? Is it a blank console, or does the program not run?

    You need to pause before exiting the program. Otherwise the command prompt window closes before you get to see the output.

    If you want to use that getch() to pause the program, you have to include <stdio.h> in addition to <conio.h>.

    But if you include <stdlib.h> or <cstdlib>, you can eliminate both of those io headers and use
    system("pause"); instead of getch();

    By nothing happening I meant that no window came up at all. If I use system("PAUSE"); then the screen just says Press any key to continue... and after you press a key it closes... this is weird.

    Exclamation The Ultimate Answer!

    Read this carefully and all your problems will be solved !

    In the int main(), before return 0; Enter the following command line-
    std::cin.get();
    This will work for your simple program,but for programs containing std::cin>> you need to type the above twice.
    This will surely make it work.

    getch() is already being used. there is no need to have std::cin.get().

    If you want to use that getch() to pause the program, you have to include <stdio.h> in addition to <conio.h>.
    You shouldn't need stdio to use getch(). I've used it before with just #include'ing conio.h.

    I've ever got this problem, when I used Dev C++.
    Trying getch() twice can fix it, I have no idea...why.
    Flushing stdout may work false.
    "\n" from stdout seems to appear in stdin.

    wherever you decide you want to pause the program.

    Which versions of Dev-C++ are you guys using? I'm using ver. 4 with Mingw compiler 2.95.2-1. When I try to compile his code without #include <stdio.h> or <cstdio> I get an error:
    "implicit declaration of function `int getchar(...)'"

    In the file conio.h, the only reference to getch() is just:
    #define getch() getchar()
    and there is no declaration for the function in this file.
    It's declared in stdio.h as
    int getchar ();

    I'm using mingw 3.2 . I just tried it, works without needing to include stdio.

    Okay instead of using Win32 I used console, and everything works fine, except now I have to relearn things because I don't program in console. Oh well, it can't hurt.
