Following is the program to find divisor of a given number.

#include<iostream.h>

#include<conio.h>
int main()
{
int i, n1;
clrscr() ;
cout<<"Enter the number to find it's divisors : " ;
cin>>n1 ;
cout<<"\nThe divisors are :\n") ;
for(i = 1 ; i <= n1 ; i++)
if(n1 % i == 0)
cout<<"\t"<<i ;
getch() ;
return 0;
}

Output:

Enter the number to find it's divisors : 21
The divisors are :
1       3       7       21
