DEMO-C-32 • Programming in C

Browser-only practice

Problem Statement

Write a program that reads two integers A and B and prints all prime numbers between A and B (inclusive).

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

Example

For input 10 20, the prime numbers in that range are 11 13 17 19.

Requirements

  • Use nested loops to solve this problem.
  • Check each number in the range [A, B] for primality.

Constraints

You must use nested loops in your solution.

Input Format

Two integers A and B on a single line, where 1 <= A <= B <= 1000.

Output Format

Print all prime numbers between A and B (inclusive), separated by spaces.
