Program to find Divisor of a Number in C++

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;
}

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