How to calculate divisors of a number (C++)

Calculate divisors of a number

displayDivisors() displays all the divisors of the number. It takes the number as an input parameter and displays all the divisors of the given number.

Code

#include "stdafx.h"

#include "iostream"

#include "conio.h"

using namespace std;

void displayDivisors(int num)

{

       for(int i=1;i<=num;i++)

       {

       if(num%i==0)

              cout<<i<<" "; 

       }

}

int main()

{

       cout<<"Divisors of    5 are : "; displayDivisors (    5 ) ;cout<<endl;

       cout<<"Divisors of    6 are : "; displayDivisors (    6 ) ;cout<<endl;

       cout<<"Divisors of   10 are : "; displayDivisors (   10 ) ;cout<<endl;

       cout<<"Divisors of   20 are : "; displayDivisors (   20 ) ;cout<<endl;

       cout<<"Divisors of   30 are : "; displayDivisors (   30 ) ;cout<<endl;

       cout<<"Divisors of   40 are : "; displayDivisors (   40 ) ;cout<<endl;

       cout<<"Divisors of   50 are : "; displayDivisors (   50 ) ;cout<<endl;

       cout<<"Divisors of   80 are : "; displayDivisors (   80 ) ;cout<<endl;

       cout<<"Divisors of   99 are : "; displayDivisors (     99 ) ;cout<<endl;

       cout<<"Divisors of  100 are : "; displayDivisors (  100 ) ;cout<<endl;

       _getche();

       return 0;

}

Output

Divisors of    5 are : 1 5

Divisors of    6 are : 1 2 3 6

Divisors of   10 are : 1 2 5 10

Divisors of   20 are : 1 2 4 5 10 20

Divisors of   30 are : 1 2 3 5 6 10 15 30

Divisors of   40 are : 1 2 4 5 8 10 20 40

Divisors of   50 are : 1 2 5 10 25 50

Divisors of   80 are : 1 2 4 5 8 10 16 20 40 80

Divisors of   99 are : 1 3 9 11 33 99

Divisors of  100 are : 1 2 4 5 10 20 25 50 100
