Question

Write a C++ code using while loop which is getting the two integers from the user, and output how many numbers are multiples of 5, and how many numbers are multiples of 7 between the two integers (inclusive).

Answer 1

C++ code:

#include <iostream>
using namespace std;
int main(){
    //initializing limits n1 and n2
    int n1,n2;
    //asking for them
    cout<<"Enter limits: ";
    //accepting them
    cin>>n1>>n2;
    //initializing i and count
    int i=n1,count5=0,count7=0;
    //looping till n2
    while(i<=n2){
        //checking if divisible by 7
        if(i%7==0)
        //incrementing count7
            count7++;
        //checking if divisible by 5
        if(i%5==0)
        //incrementing count5
            count5++;
        //incrementing i
        i++;
    }
    //printing Count5
    cout<<"Count of number divivsible by 5: "<<count5<<endl;
    //printing Count7
    cout<<"Count of number divivsible by 7: "<<count7<<endl;
    return 0;
}
