Prime or Not

Write a program that reads a number and then find if the number is prime or not. If the number is not prime, print all the factors.

#include<iostream>
using namespace std;
void factors(int a){
	for(int i=1;i<=a;i++){
		if(a%i==0)cout<<" "<<i;
	}
}
int main(){
	int a;
	cout<<"Enter a positive number : ";
	cin>>a;
	int count=0;
	for(int i=1;i<=a/2;i++){
		if(a%i==0)count++;
	}
	if(count==1)cout<<"Prime"<<endl;
	else cout<<"Not Prime"<<endl;
	if(count>1)
	{
		cout<<"The factors of "<<a<<" are ";
		factors(a);
	}
	return 0;
}
