How do I perform operations on 1D arrays in C++?

You can perform various operations like addition, subtraction, and searching on 1D arrays in C++. What specific operation are you interested in?

Can you show me how to add two 1D arrays?

Sure! Here's a simple example:

#include <iostream>
using namespace std;

int main() {
    int arr1[] = {1, 2, 3};
    int arr2[] = {4, 5, 6};
    int sum[3];

    for (int i = 0; i < 3; i++) {
        sum[i] = arr1[i] + arr2[i];
    }

    for (int i = 0; i < 3; i++) {
        cout << sum[i] << " ";
    }
    return 0;
}

This will output the sum of the two arrays.

What if the arrays have different sizes?

If the arrays have different sizes, you'll need to handle that by either limiting the operation to the smaller array's size or by defining a new array that can accommodate the larger size. Would you like an example?

Yes, please!

Here's how you can handle arrays of different sizes:

#include <iostream>
using namespace std;

int main() {
    int arr1[] = {1, 2, 3};
    int arr2[] = {4, 5};
    int maxSize = max(sizeof(arr1)/sizeof(arr1[0]), sizeof(arr2)/sizeof(arr2[0]));
    int sum[maxSize];

    for (int i = 0; i < maxSize; i++) {
        sum[i] = (i < sizeof(arr1)/sizeof(arr1[0]) ? arr1[i] : 0) + (i < sizeof(arr2)/sizeof(arr2[0]) ? arr2[i] : 0);
    }

    for (int i = 0; i < maxSize; i++) {
        cout << sum[i] << " ";
    }
    return 0;
}

This will add elements where available and treat missing elements as zero.
