Answer:
#include <bits/stdc++.h>
using namespace std;
bool isPrime(int n)
{
    for(int j=2;j<=n-1;j++)  //loop to check prime..
    {
        if(n%j==0)
        return false;
    }
    return true;
}
int main(){
    int n;
    cout<<"Enter the integer"<<endl;//taking input..
    cin>>n;
    if(isPrime(n))//printing the message.
    {
        cout<<"The number you have entered is prime"<<endl;
    }
    else
    {
        cout<<"The number is not prime"<<endl;
    }
 return 0;
}
