C programe to check prime number or not using if condition

Answer 1

step 1: ask user to input a number.

step 2: (optional-but will be good) check if user input number is positive or not.

step3: Iterate through all the numbers starting from 2 to (N/2) using a for loop and for every number check if it divides N. If we find any number that divides, we return false. If we did not find any number between 2 and N/2 which divides N then it means that N is prime and we will return True.
