Lets write a C program to find and print / display all the prime numbers from 2 to N. Here N is the user entered number / limit.
Prime Number: Any natural number which is greater than 1 and has only two factors i.e., 1 and the number itself is called a prime number.
We apply square root to the user entered number and store it inside variable inum. This reduces the number of iterations of inner while loop.
So its enough if we iterate through the while loop sqrt(num) times to check if the user entered number is divisible by any number other than 1 and itself.
