HELP when I run this program (in c language) and input the value 2 the output comes out to be 99. I'm using GNU GCC compiler. Can anyone please explain?

Question

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

int main()
{
int x,y;
printf("\n\nenter the value of 10 = ");
scanf("%d",&x);

y=pow(10,x);

printf("\nRESULT OF POWER OF Y = %d\n",y);
return 0;
}

Answer 1

Re-install your compiler. The code should work.

Answer 2

Because of integer truncation. pow()returns a floating point value, and due to floating point arithmetic, it is probably ~99.999...; however, due to integer truncation, even 99.999... gets truncated down to 99.
