Question

How to multiply all the elements of an array in C++

Answer 1

#include <iostream>

int main() {
    int arr[] = {2, 3, 4, 5}; 
    int n = sizeof(arr) / sizeof(arr[0]); // Calculate the size of the array

    int product = 1; // Initialize product to 1
    for (int i = 0; i < n; i++) {
        product *= arr[i]; // Multiply each element
    }

    std::cout << "The product of all elements is: " << product << "\n";
}



/*
run:

The product of all elements is: 120
