3.Write a program in C that describe a complex mathematical formula with nested comments.

#include <stdio.h>
int main()
{
 // Declare and initialize variables for the complex formula
  int p = 2,q=3,r=3;
 int res; // res is variable to store the result
  /* Let study and solve the following complex formula:
  res = (p + q) * (q - r) / (p % r); // Perform the calculations
  */
  res = (p + q) * (q - r) / (p % r);
  // show the final result
  printf("\n The answer of the given complex formul =: %d ", res);
 return 0;
}
Output:
The answer of the given complex formul =: 0
