Question

Write a program that has a while loop to print out the first five multiples of 15, 43, and 273 between the numbers of 3168 and 376020. Put each of the three sets of multiples on a new line.

Answer 1

Answer:

#include <iostream>

using namespace std;

void printmultiples(int n) //function to print first five multiples between 3168 and 376020

{

   int a =3168,c=1;

   cout<<"First five multiples of "<<n<<" are : ";

   while(a%n!=0 && a<=376020) //finding first mutiple of n after 3168.

   {

       a++;

   }

   while(c<6)//printing multiples.

   {

       cout<<a<<" ";

       a+=n;

       c++;

   }

   cout<<endl;

}

int main() {

   int t,n;

   cin>>t;//How many times you want to check.

   while(t--)

   {

       cin>>n;

       printmultiples(n);//function call..

   }

return 0;

}

Input:-

3

15

43

273

Output:-

First five multiples of 15 are : 3180 3195 3210 3225 3240  

First five multiples of 43 are : 3182 3225 3268 3311 3354  

First five multiples of 273 are : 3276 3549 3822 4095 4368

Explanation:

I have used a function to find the first five multiples of the of the numbers.The program can find the first five multiples of any integer between 3168 and 376020.In the function I have used while loop.First while loop is to find the first multiple of the integer n passed as an argument in the function.Then the next loop prints the first five multiples by just adding n to the first multiple.

In the main function t is for the number of times you want to print the multiples.In our case it is 3 Then input the integers whose multiples you want to find.
