C Exercises: Find the product xyz

C Programming Practice: Exercise-25 with Solution

A Pythagorean triplet is a set of three natural numbers, x < y < z, for which,
x2 + y2 = z2
For example, 32 + 42 = 9 + 16 = 25 = 52.
There exists exactly one Pythagorean triplet for which x +y + z = 1000.
Write a C programming to find the product xyz.

C Code:

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

int main(void)
{
  int x, y;

  for (x = 1; x <= 333; x++) {
    for (y = x; y <= 666; y++) {
      int z = (1000 - x - y);
      if (x*x + y*y == z*z) {
      	printf("Numbers are: %d, %d, %d ", x, y, z);
        printf("\nProduct of x, y, z is : %d", x * y * z);
      }
    }
  }
  return 0;
}

Sample Output:

Numbers are: 200, 375, 425 
Product of x, y, z is : 31875000

Maximum value of int:

In C:

#include <limits.h>
then use
int imin = INT_MIN; // minimum value
int imax = INT_MAX;

or

#include <float.h>

float fmin = FLT_MIN;  // minimum positive value
double dmin = DBL_MIN; // minimum positive value

float fmax = FLT_MAX;
double dmax = DBL_MAX;
