How do I pass arrays in C++?

How do I pass arrays in C++?

In C++, you can pass arrays to functions by using pointers or by specifying the array type in the function parameters.

Can you show me an example of passing an array to a function?

Sure! Here's a simple example:

#include <iostream>
using namespace std;

void printArray(int arr[], int size) {
    for (int i = 0; i < size; i++) {
        cout << arr[i] << " ";
    }
    cout << endl;
}

int main() {
    int myArray[] = {1, 2, 3, 4, 5};
    printArray(myArray, 5);
    return 0;
}

What happens if I pass an array with the wrong size?

If you pass an array with the wrong size, it can lead to undefined behavior, such as accessing out-of-bounds memory.

Are there any alternatives to passing arrays?

Yes, you can use std::vector from the Standard Template Library (STL) for dynamic arrays, which manage their own size.
