Float to Mixed Numbers

[mqazi]

why strcmp not comparing strings ?

#include <stdio.h>
#include <string.h>

main()
{
   float n = 0.5;
   float x = 0;
   char buff[2], b[2];
     sprintf(buff, "%f", n);
   int i = 1;
   for(i = 1; i <= 100; i++){
       x = (1.0/i);
       sprintf(b, "%f", x);
       if(!strcmp(buff, b)){
           
           printf("%d / %d\n", 1, i);
           break;
       }
       
   }
   
}

buff and b aren't large enough and are almost certainly being overwritten.

You should never use sprintf, use snprintf instead.
