//  Write a program that reads a string from the standard input into a
//  dynamically allocated character array.
//  Describe how your program handles varying size inputs.
//  Test your program by giving it a string of data that is longer than the
//  array size you've allocated.

#include <iostream>

int main()
{
    // need to tell the size.
    std::cout << "How long do you want the string? ";
    int size{0};
    std::cin >> size;
    char* input = new char[size + 1]();
    std::cin.ignore();
    std::cout << "input the string: ";
    std::cin.get(input, size + 1);
    std::cout << input;
    delete[] input;
    // Test: if longer than the array size, we will lost the characters which
    // are out of range.
