Answer 1

3.

Program:

#include <iostream>

using namespace std;

void change(int arr[], int n);

int main() {

int arr[50]; // variable Declaration

int n; // variable Declaration

cout<<"Enter number of elements in the array: ";

cin>>n; // accept the number of elements

cout<<"Enter array elements:\n";

for(int i=0; i<n; i++) // loop to accept elements

cin>>arr[i];

cout<<"Array elements before chnaging: ";

for(int i=0; i<n; i++) // loop to print elements

cout<<arr[i]<<" ";

change(arr, n);

cout<<"Array elements after chnaging: ";

for(int i=0; i<n; i++) // loop to print elements

cout<<arr[i]<<" ";;

cout<<endl;

return 0;

}

void change(int arr[], int n){ // called function

cout<<"\nEnter new array elements you want to change: ";

for(int i=0; i<n; i++) // loop to print elements

cin>>arr[i];

}

output:
