Thread: Just starting out, this program will compile but freezes when run?

Hi, I am very new to programming and have written a very simple program to convert inches to mm and spit out the results. This program compiles just fine (running OpenSUSE through Oracle VirtualBox) but when I run it, nothing ever happens and it never finishes (ie it seems to have frozen). Again, I am extremely new to this, so forgive me for any mistakes, but here is the program:

Code:

#include <stdio.h>

#define MAX 100
#define STEP 10
#define CONVERSION 25.4

main()
{
  float inch, mm;
  inch=0;
  while (inch<=MAX);
     {
     mm=inch*CONVERSION;
     printf ("%f\t %f\n", inch, mm);
     inch=inch+STEP;
     }
  return 0;
}

Code:

while (inch<=MAX);

Look. Look closely.... There's a semicolon there when there shouldn't be. This means:

Code:

while (inch<=MAX)
       ;     // do nothing
<some more code that won't get run.....>

You seem to have an errant semicolon after your while statement.
