[BUG] check_prime.cpp returns incorrect output for 9

[codingbbq]

Description

If you check the number 9 for prime, it returns true.

Expected Behavior

is_Prime(9) should return false

Actual Behavior

is_Prime(9) should return true

Possible Fix

Changes in the for loop ?

I have fixed the bug.

//Before :-

Enter the number to check if it is prime or not
9 is a prime number

// After
Enter the number to check if it is prime or not
9 is not a prime number
