Passing Arrays to Functions in C++

Arrays can be passed to functions by specifying the array name without brackets. Functions can then work on the entire array.

Example: Passing an Array to a Function

#include <iostream>

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

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

Explanation: The printArray function takes an array and its size as arguments, allowing it to iterate and print the array's elements.

Key Takeaways

  • Arrays are passed by reference (without copying).
  • The function can access and modify array elements.
  • Specify the array size as an additional parameter for flexibility.
