bool isPrime = checkPrime(num);//function checkPrime is called
if(isPrime == true)
cout << endl<<num << " is a prime number.";
else
cout <<endl<<num << " is not a prime number.";
return 0;
}
int checkPrime(int n)
{
bool flag = true;
for(int i = 2; i <= n/2; ++i)//running for loop from 2 to half the input number
{
if(n%i == 0)
{
flag = false;
break;
