To print the power of the number in c using cygwin terminal

I am unable to find the exact solution of 2 raise to the power 32 in the following program. I am using cygwin terminal.

#include <stdio.h>

main()
{
  int base, expo;

  long long value = 1;
  printf("Enter base number and exponent respectively");
  scanf("%d%d", &base, &expo);

  while (expo != 0)
  {
    value *= base;
    --expo;
  }
  printf("Answer = %ll ", value);

  return 0;
}

I would want some help in knowing what datatype would be appropriate for storing the value of 2 raise to 32.

Solution

  • 232 is equal to 4294967296. This can be easily resented by long long type. Use %lld specifier.
