Do you want to write an Algorithm to check for prime numbers. This code below is just what you need. Now let’s get started.
Algorithm to check for prime numbers
Step 1: Start
Step 2: Declare variables num, i
Step 3: Initialize variables
i= 2
Step 4: Read num from user.
Step 5: Repeat the steps until i<(num/2)
5.1 If remainder of n/i equals 0
Go to step 6
else Goto step 7
Step 6: display num is not a prime number
Step 7: display num is prime number
Step 8: stop
#Below is the python program… ????
PYTHON CODE
print(“To check for prime numbers “)
num= int(input(“Enter a number: “))
if num > 1:
for i in range(2, num):
if num%i == 0:
print(num, ” is not a prime number”)
print(i, ” times “, num//i, ” is “, num)
break
else:
print(num, ” is prime number”)
else:
print(num, ” is not prime “)
