Largest among three number using pointer & function in C

User-defined function find is defined to get large number among three numbers. To get this pointer is passed as parameter to the function. Variable declared is assigned to the pointer.

#include<stdio.h>
void find(int *x, int *y, int *z);
int main()
{
  int a, b, c;
  int *pa, *pb, *pc;
  pa= &a, pb= &b, pc=&c;
  printf("Enter three number: ");
  scanf("%d %d %d", pa, pb, pc);
  find(pa, pb, pc);
  return 0;
}
void find(int *x, int *y, int *z)
{
  if( (*x > *y) && (*x > *z) )
    printf("Largest = %d", *x);
  else if((*y > *x) && (*y > *z))
    printf("Largest = %d", *y);
  else
    printf("Largest = %d", *z);
}

Output:

Enter three number: 78 99 32
Largest = 99
