Question

Please write variables and program plan (pseudocode) of the C++ programming below:

#include <iostream>
#include <cmath>

using namespace std;

void divisors(int num);

int main ()
{
   char repeat;
   int num;
  
   while (repeat !='n')
   {
       cout << "Enter a number: ";
       cin >> num;
       divisors(num);
       cout << "Continue? (y or n): ";
       cin >> repeat;
   }
   return 0;
}

void divisors(int num)
{
   int divCount = 0, sum = 0;
  
   cout << "Proper divisors: ";  
   for (int div = num-1; div > 1; div--)
   {
       if (num % div ==0)
       {
           cout << div << " ";
           sum += div;
           divCount++;
       }
   }
   cout << endl;
   cout << "Number of proper divisors = " << divCount << endl;
   cout << "Sum of proper divisors = " << sum << endl;
}
  

Answer 1

This program is to find for a given number find the proper divisors, no.of proper divisiors, and sum of proper divisors

Pseudocode:

int main(){

declare num as int

declare repeat as char

while(repeat != 'n'){

take input from ther user = num

divisors(num)

}

}

void divisors(int num){

int divcount=0,sum=0;

for(int div = num-1;div>1,div--){

if(num % div == 0){

print div

sum += div;

divcount++;

}

}

print divcount

print sum

}

Variable used in this program

repeat as char

num as int

divcount as int

sum as int

div as int
