How to multiple all members of the array?

Answer 1

#include <iostream>
using namespace std;

int main() {
int a[]={1,2,3,4};
int multiply = 1;
for(int x : a)
multiply*=x;
cout << multiply;
return 0;
}

Answer 2

How about this?

int a[] = { 1, 2, 3 };

for(auto &i : a)
++i;

Answer 3

I think you mean multiply:

int main() {
int arr[] = {2, 3, 4};
int total = 1;
for (int num: arr) {
total *= num;
}
return 0;
}

Answer 4
