It's probably some super simple thing that I would see right away if I weren't a beginner. And by the way, let me redo that with comments.
Code:
/*
Programmer : Caleb Spiess
Date : 12/18/11
Description : The program is supposed to output 1 - 99. It doesn't work yet.
***************************************************
*/
#include <stdio.h>
int main( ) //main body
{
int x=1; //declares x to be 1
while(x<100); //keeps the loop going while x is less than 100
printf("%d\n",x); //this should print x every loop
x = x + 1; //this should add 1 to x every loop
getchar(); //this makes sure that the program doesn't breeze by the user : the idea is that they can press any key to continue
return 0; //returns a value, indicating to the program that there was success
}
