Because so many dynamic memory, I expected the list 2 3 5 to be a little slower than the 2 3 5 hard-coded. But it was ok as you can see bellow.

After that, time got smaller and smaller, culminating the best list to be: So if someone would create a hardcoded program that makes use of such technique I would suggest use the list 2 3 and 5, because the gain is not that big.

But also, if willing to code, this list is ok. Problem is you cannot state all cases without a loop, or your code would be very big There would be ORs, that is in the respective internal if. Here the whole test: Cannot allocate memory PS. I did not free r intentionally, giving this task to the OS, as the memory would be freed as soon as the program exited, to gain some time.

But it would be wise to free it if you intend to keep running your code after the calculation.C++ Program to Check Whether a Number is Prime or Not. Example to check whether an integer (entered by the user) is a prime number or not using for loop and if else statement.
