bookPass the Array

You can pass to your function whatever parameters you want, and even arrays!

For instance, here, we pass the array and its size as arguments:

void printArr(int arr[], int size) {
    for(int x = 0; x < size; x++) {
        cout << arr[x] << " ";
    }
}

Here we pass to the function an integer array and its size as arguments . Then we go through the array using for loop to print each element. The whole code:


              
12345678910111213

            
#include &ltiostream&gt
using namespace std;

void printArr(int arr[], int size) {
&nbsp;&nbsp;&nbsp;&nbsp;for(int x = 0; x < size; x++) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;cout << arr[x] << " ";
&nbsp;&nbsp;&nbsp;&nbsp;}
}

int main() {
&nbsp;&nbsp;&nbsp;&nbsp;int arr[] = {1, 2, 3, 4};
&nbsp;&nbsp;&nbsp;&nbsp;printArr(arr, 4);
}

Pass the string array x as an argument of the function:

void myFunc(,size)

Var allt tydligt?
