Prime Prime Prime Help Help Help
hi everyone, i have being working on this code for a long time.. but couldnt make it right
it is simple find the prime number from the user inputs
this is the code ....
Code:
bool IsPrime(int iNum)
{
// Check if i is less than square root of iNum (and cast iNum to type double)
for (int i=2; i<=sqrt((double)iNum); i++)
{
if (iNum == ((int)iNum/i)*i)// (inum%i == 0)
return false;
}
return true;
}
but this is not the exact code that i want ...
my aim is to find the prime number that the user will input the max number,,,
example here:
input: 4
output will be: not prime..
please help ...... i know there are lot of related topic but .... still couldnt help.
