listing4.2.cpp Assigning Values to Elements in an Array

//listing4.2.cpp
#include <iostream>
using namespace std;
constexpr int Square(int number){return number*number;}

int main()
{
    const int ARRAY_LENGTH=5;

    //array of 5 integers, initialized to 5 values
    int myNumbers[ARRAY_LENGTH]={5,10,0,-101,201};

    //using a constexpr for array of 5*5=25 integers
    int moreNumbers[Square(ARRAY_LENGTH)];

    cout << "Enter index of the element to be changed: ";
    int elementIndex=0;
    cin >> elementIndex;

    cout << "Enter new value: ";
    int newValue=0;
    cin >> newValue;

    myNumbers[elementIndex]=newValue;
    moreNumbers[elementIndex]=newValue;

    cout << "Element " << elementIndex << " in array myNumbers is: ";
    cout << myNumbers[elementIndex] << endl;

    cout << "Element " << elementIndex << " in array moreNumbers is: ";
    cout << moreNumbers[elementIndex] << endl;

    return 0;
}

output:

Enter index of the element to be changed: 0
Enter new value: 13
Element 0 in array myNumbers is: 13
Element 0 in array moreNumbers is: 13
