C program to find Sum & average in Range using Pointer & Function

User-defined function calculate() is defined to calculate sum and average and pointers are assigned to variables declared. Hence , pointers are passed as parameters to function.

#include<stdio.h>
double calculate(int *m, int *n, double *sum, double *avg);
int main()
{
  int m, n;
  int *pm, *pn;
  pm= &m, pn= &n;
  double sum=0.0, avg;
  double *psum, *pavg;
  psum= &sum, pavg= &avg;
  printf("Enter m & n Values(m<n): ");
  scanf("%d %d", pm, pn);
  calculate(pm, pn, psum, pavg);
  printf("Sum= %.2lf and average= %.2lf\n", *psum, *pavg);
  return 0;
}
double calculate(int *m, int *n, double *sum, double *avg)
{
  int i;
  for(i=*m; i<=*n; i++)
  {
    *sum += i;
  }
  *avg = (*sum) / (*n -*m + 1);
}

Output:

Enter m & n Values(m<n): 40 50
Sum= 495.00 and average= 45.00
