Thread: Loop Problem

There is no error at least that Pelles C can find. I am just learning how loops work, and I am trying to figure out how to print out 1 - 99 without a bijillion printfs. Here is the code.

Code:

#include <stdio.h>

int main( )
{
    int x=1;
while(x<100);
    printf("%d\n",x);
    x = x + 1;
getchar();
return 0;
}

Like I said, no error code.

Look closely at the end of your while loop.

Some errors.
Should be:

Code:

#include <stdio.h>
int main(void){
     int x=1;
     while(x<100){
              printf("%d  \n",x);
              x = x + 1;       //you can also us x++;
    }
      getchar();
      return 0;
}

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
}

Wow. Thanks, FloridaJo. I was right - that was amazingly simple. I will remember that syntax forever, mostly because it caused me so much trouble not to.

Lesson #1 ... "Compiles" does not mean "Works".
