Question

write a program in Java to enter a number and display the first three multiples of the number
(using functions)

Answer 1

// A Simple C++ program to find count of all

// numbers that multiples

#include<iostream>

using namespace std;

// Returns count of all numbers smaller than

// or equal to n and multples of 3 or 7 or both

int countMultiples(int n)

{

int res = 0;

for (int i=1; i<=n; i++)

if (i%3==0 || i%7 == 0)

res++;

return res;

}

// Driver code

int main()

{

cout << "Count = " << countMultiples(25);

}
