Can arrays be used as function parameters?

Yes, in many programming languages, arrays can be used as function parameters, and the function will perform operations on the data stored in it. For example, the printArray function in C++ can print the elements in an array, while the printArray function in Python can iterate over an array and print its elements. Modifications made to the array by these functions are also reflected in the original array in the calling function.

Can arrays be used as function parameters?

Yes, arrays can be used as function parameters.

In many programming languages, arrays can be passed to functions just like other types of data (such as integers, strings). This enables functions to process the data stored in the array, performing various operations (e.g. sorting, searching).

C++ Example:

#include <iostream>
#include <vector>

using namespace std;

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

int main() {
  int arr[] = {1, 2, 3, 4, 5};
  int size = sizeof(arr) / sizeof(arr[0]);

  printArray(arr, size);

  return 0;
}

Python Example:

def printArray(arr):
  for element in arr:
    print(element, end=" ")
  print()

arr = [1, 2, 3, 4, 5]

printArray(arr)

Java Example:

public class ArrayAsFunctionParameter {

  public static void printArray(int[] arr) {
    for (int element : arr) {
      System.out.print(element + " ");
    }
    System.out.println();
  }

  public static void main(String[] args) {
    int[] arr = {1, 2, 3, 4, 5};

    printArray(arr);
  }
}

Note:

When passing an array, a reference to the first element of the array is passed. This means that the function can modify the elements in the array, and these modifications will also be reflected at the point where the function is called.
