Input a random positive integer, n.

Create an empty character array with a size of the inputted random positive integer, n.

In the next succeeding lines, store the n characters into the character array.

Answer 1

#include <iostream>

using namespace std;

int main()
{
	int n;
	cout << "Please, enter a size of character array: ";
	cin >> n;
	char* arr = new char[n];
	cout << "Please, enter characters: ";
	for (int i = 0; i < n; i++)
	{
		cin >> arr[i];
	}
	int m;
	cout << "Please, enter an integer value between 0 to n-1: ";
	cin >> m;
	if (m < 0 || m > n - 1)
		cout << "Incorrect value!";
	else
		cout << "Value arr[m] = " << arr[m];
