  • Write a program to Print All Prime Numbers Between n and m using While loop in Java Script
  • Write a program to Print All Prime Numbers Between n and m using While loop in C#

Explanation:

Steps

  1. Input: Take the lower limit n and upper limit m.
  2. Prime number check:
    • A prime number is greater than 1 and divisible only by 1 and itself.
    • For each number i between n and m, check if it is prime:
      • Loop through numbers from 2 to sqrt(i) to see if any number divides i.
      • If no number divides i, it is prime.
  3. Print primes: Display all numbers identified as prime.

Explanation:

  • For n = 10 and m = 50:
  • Numbers between 10 and 50 are checked for primality.
  • Prime numbers in this range are printed: 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47.
