Question

• First, create a function called addNumber, which has a formal parameter for an array of integers and increase the value of each array element by a random integer number between 1 to 10. o Add any other formal parameters that are needed. • Second, create another function called printReverse that prints this array in reverse order. • Then, you need to write a C++ program to test the use of these two functions.

Answer 1

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

void addNumber(int arr[], int size) {
    for (int i = 0; i < size; ++i) {
        arr[i] += 1 + (rand() % 10);
    }
}

void printReverse(int arr[], int size) {
    for (int i = 0; i < size; ++i) {
        cout << arr[size-i-1] << " ";
    }
    cout << endl;
}

int main() {
    srand(time(NULL));
    int arr[] = {5, 9, 1, 2, 7, 6}, size = 6;
    printReverse(arr, size);
    addNumber(arr, size);
    printReverse(arr, size);
    return 0;
}
