    Help with Loops

    I'm just starting out with C and I'm off to a bad start. First off, this isn't homework, this is just me trying to familiarize myself with the idea of the Loops. I have two programs, neithither of which are compiling through the Virtual Box uBuntu and the terminal emulator. I got the code off of this site's tutorial.

    Any insight?

    This is the while loop.
    Code:
    #include <stdio.h>
    
    intmain()
    {
        int x = 0;
        
        while ( x < 10 ) {
            printf( "%d \n", x );
            x++;
        }
        getchar();
    }
    And here is the for loop.
    Code:
    #include<stdio.h>
    
    int main()
    {
        int x;
        for (x=0; x < 10; x++) 
        {
            printf( "%d\n", x );
        }
        getchar();
    }
    I'm aware that these should be two very easy concepts consdering the semester is only 3 weeks in.

    Thanks for any help!

    int main() should be returning 0 on it's last line of code. That's what the "int" means. (That 0 goes to the operating system, and is usually used to mean the program ran without run-time errors).

    "intmain" should be int main, in the first example, of course.

    And welcome to the forum, Robert!

    Why not? If it doesn't tell you why they don't compile, use something that will give you a list of errors. Like a real compiler.

    Appreciate the feedback, I'll give it a run.

    @WaltP - I'm a student at Clemson, I just use what they tell me to...

    EDIT: Works now. Thanks a bunch!

    Not the point. Things that are broken make errors.

    Code:
    #include <stdio.h>
    
    intmain()
    {
        int x = 0;
    
        while ( x < 10 ) {
            printf( "%d \n", x );
            x++;
        }
        getchar();
    }
    
    C:\Users\Josh2\Documents\foo\main.c:4: warning: return type defaults to 'int'
    C:\Users\Josh2\Documents\foo\main.c: In function 'intmain':
    C:\Users\Josh2\Documents\foo\main.c:12: warning: control reaches end of non-void function
    Process terminated with status 0 (0 minutes, 0 seconds)
    0 errors, 2 warnings
    This is often an extremely useful list for people answering questions.

    It gave a huge list of errors, I just brainfarted and didn't think about "intmain()" being "int main()" ... It worked fine after that.
