Title: Question about Loops
Post by: Apbullington18 on October 23, 2018, 05:47:38 pm

#include <stdio.h>
main()
{
int x = 0;
while (x < 5)
{
    printf(" ",x,"\n");
    x++;
}
return 0;
}

I can't get this program to run in CodeBlocks.  It's just a simple while loop, but nothing comes out when run.  I'm new to coding so forgive me if i'm naive.

That printf statement isn't doing what you think it is, it's just printing space characters.  You'll probably want to do printf(" %d\n", x); instead.  If you enabled all the optional warnings in your compiler, you would likely get a warning that you passed too many arguments (ie, x and "\n" being ignored because the format string didn't call for the use of any additional arguments).
