Question

#include <iostream>
#include <time.h>
#include <stdlib.h>
using namespace std;

int main()
{
setlocale(LC_ALL, "RUSSIAN");
int a[15], b[15], i, j = 0;
cout << "Array: " << endl;

for (i = 0; i < 15; i++)
cin >> a[i];

for (i = 0; i < 15; i++)
if ((a[i] % 4) == 0) {
b[j] = a[i]; j++;
};

cout << "Array : " << endl;
for (i = 0; i < j; i++)
cout << b[i] << endl;
return 0;
}

Answer 1

You don't need another array. Use your original array and use if(a[i] % 3 == 0) to get indexs that are the multiple of 3. And cout << a[i];

Are you looking for a multiple of 3 in array <a> or only in array <b>? cause I see you are filtering only multiples of 4 from array <a> into array <b>.

I confirmed this in your previous thread, but you did not respond ...
