Add two Array in C++

To add two arrays in C++, you can create a new array that stores the sum of corresponding elements from the two input arrays. Here’s an example of how to do this:

C++
#include <iostream>

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

    // Add the corresponding elements from array1 and array2
    for (int i = 0; i < size; ++i) {
        sumArray[i] = array1[i] + array2[i];
    }

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

    return 0;
}

In this program:

  • We declare two arrays, array1 and array2, each with the same size (size).
  • We also declare a third array, sumArray, of the same size to store the sum of the corresponding elements of array1 and array2.
  • We use a for loop to iterate through the elements of the arrays and add the corresponding elements together, storing the result in sumArray.
  • Finally, we display the sumArray to show the result.

When you run this program, it will add the two input arrays element-wise and display the sum.
