Adding Two Arrays in C++

The add two arrays element-wise by iterating through them and adding corresponding elements together. Here’s an example of how you can do this:

C++
#include <iostream>

int main() {
    const int size = 5; // Define the size of the arrays
    int array1[size] = {1, 2, 3, 4, 5};
    int array2[size] = {6, 7, 8, 9, 10};
    int sum[size]; // Resultant array to store the sum

    // Add the elements of array1 and array2 element-wise
    for (int i = 0; i < size; ++i) {
        sum[i] = array1[i] + array2[i];
    }

    // Display the result
    std::cout << "Sum of arrays:" << std::endl;
    for (int i = 0; i < size; ++i) {
        std::cout << sum[i] << " ";
    }
    std::cout << std::endl;

    return 0;
}

In this example, we have two arrays array1 and array2, each containing five integers. We create a third array sum to store the result of the addition. We iterate through both array1 and array2 using a loop, adding the elements at the same index and storing the result in the corresponding index of the sum array.

After the addition, we display the elements of the sum array, which will contain the result of adding array1 and array2 element-wise.

Keep in mind that this code assumes that both array1 and array2 have the same size. If they have different sizes, you may need to handle that situation accordingly to avoid accessing out-of-bounds memory.
