Answer 2

Program in python :

Explanation:

number=int(input("Enter the number: "))#take a input from the user.

i=2

count=0

while(i<=(number/2)):#while loop which checks the number to be prime or not.

   if(number%i==0):

       count=1

   i=i+1

if(count==0):

   print("The number is a prime number")

else:

   print("The number is not a prime number")

Output:

• If the user input as 4, then it will prints not a prime number.
• If the user inputs as 2, then it will prints the prime number.

Code Explantion :

• The above code is in python language, which takes the inputs from the user and then runs the while loop up to the number divisible by 2.
• Then checks the number to be divisible by all the value which is less than from that number.
• If no number can divide that number, then it is a prime number.
