the problem is, i have no idea where to start. i know it involves things like while loops but im not sure how to get it to determine if its prime or not.

void main()
{
	int i,j;
	bool bPrime=true;

	cout<<"enter the number ( greater and equal to 2 ) : ";
	cin>>i;

	for(j=2;j<i-1;j++)
	{
		if(i%j==0)
		{
			bPrime=false;
			break;
		}
	}

	if(bPrime)
		cout<<endl<<i<<" Number is prime";
	else
		cout<<endl<<i<<" Number isnot prime";

}
