C Program to find Largest among three number using the pointer

We have three numbers x, y, and z in the following program. The addresses of these three numbers have been given to three pointers, px, py, and pz, correspondingly. Using an if else statement, we later performed a comparison on the values stored at the positions specified by pointers.

#include<stdio.h>
int main()
{
  float x, y, z;
  float *px, *py, *pz;
  px=&x, py=&y, pz=&z;
  printf("Enter three number:");
  scanf("%f %f %f", px, py, pz);
  if(*px > *py)
  {
    if(*px > *pz)
      printf("Biggest = %.2f", *px);

    else
      printf("Biggest = %.2f", *pz);
  }
  else
  {
    if(*py > *pz)
      printf("Biggest = %.2f", *py);

    else
      printf("Biggest = %.2f", *pz);
  }
  return 0;
}

Output:

Enter three number:55 67 45
Biggest = 67.00
