## Introduction

I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.

#include <iostream> using namespace std; // Function declarations int isPrime(int num); void printPrimes(int lower, int upper); int main() { int lower, upper; cout<<"Enter the lower and upper limit to list primes: "; cin>>lower; cin>>upper; // Calling function to print all primes between the given range. printPrimes(lower, upper); return 0; } // Print all prime numbers between lower limit and upper limit. void printPrimes(int lower, int upper) { cout<<"List of prime numbers between "<<lower <<" and "<<upper <<" are: "<<endl; while(lower <= upper) { // Printing if current number is prime if(isPrime(lower)) { cout<<lower<<endl; } lower++; } } //Checking whether a number is prime or not int isPrime(int num) { int i; for(i=2; i<=num/2; i++) { /* If the number is divisible by any number other than 1 and self then it is not prime */ if(num % i == 0) { return 0; } } return 1; }
