(HackerRank) Write a Modular C Programming code to solve Finding Primes, Write a user-defined function checkprime() to check the roll number of a student in a classroom is a prime.
Karan was late to school by 15 minutes. The teacher punished him to perform the following task:
The teacher told him to go to each classroom of different divisions, call out all the students whose roll number is prime and collect Rs. 10/- from each.
Karan has to collect money and give away a treat to his classmates and teacher.
Find out how much maximum money he collects.
Additional Info:
