Check Whether Number Is Prime Or Not In C

1st Iteration: i = 2 Here, the program checks if n modulo i equals 0. 29%2 != 0; thus, c is not incremented and remains 0. i is incremented for the next iteration, so i = 3 . 2nd Iteration: i = 3 Here, if n % i == 0, then c would be incremented. 29%3 != 0; thus, c is not incremented and remains 0. i is incremented for the next iteration, so i = 4 . Definition : A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. The first few prime numbers are 2, 3, 5, 7, 11,.. The idea to solve this problem is to iterate through all the numbers starting from 2 to sqrt (N) using a for loop and for every number check if it divides N.
