The output of the program
Prime Number
Explanation of the Program:
- Making a function for checking the parameter passing is a prime number or not
- If-condition for checking that the given number is less than 1 or equal to 1
- if the given number is less than 1 or equal to 1 then it returns false
- and then move to the for loop statement where the number is divided by the iteration number and compared with zero for leaving no reminder
- on condition true return false else return true
- and after that calling the prime number function in if-condition with an argument passing
- if the condition is true then the number is a prime number else it is not a prime number
