Comment on Tutorial : Checking Prime Number in C++ By Grant Braught
This program is mush faster and finer than given program.



#include <iostream>
#include <math.h>

bool IsPrime(int number)
{
for (int i=2; i<sqrt(number/2); i++)
{
if (number % i == 0)
{
return false;
}
}

return true;
}
int main()
{
int number;

cout << \"Enter an integer: \";
cin >> number;

if (IsPrime(number))
cout << number << \" is prime.\" << endl;
else
cout << number << \" is not prime.\" << endl;

return 0;
}
