Question

    #include<stdio.h>
    void main()
    {
          float i,j;
          i=??;
          j=i+1;
          if(i==j)
               printf("Bug");
    }

My teacher gave me this qns to find the value of i so that the printf executes.
He said this is a common bug in a lot of languages.

Answer 1

Always try the boundaries for odd behavior. This worked for me:

#include <float.h>


int _tmain(int argc, _TCHAR* argv[])
{
    float i,j;

    i = FLT_MAX;
    j = i + 1;

    if(i == j)
    {
        printf("they're the same");
    }


    return 0;
}
