How to Take std::cin Input with Spaces?

// C++ program to take std::cin input with spaces
#include <iostream>
#include <locale> // to work with locales
#include <string>
using namespace std;
// Defining a structure that inherits from ctype<char>
struct changeDelimiter : ctype<char> {
    // Constructor for changeDelimiter
    changeDelimiter()
        : ctype<char>(
            createTable()) // Initializing the base class
                           // ctype<char> with a table
    {
    }
    // Static function to create a table with custom
    // settings
    static mask const* createTable()
    {
        static mask
            rc[table_size]; // Creating a table with the
                            // size of the character set
        rc['\n']
            = ctype_base::space; // Set the newline
                                 // character to be treated
                                 // as whitespace
        return rc; // Return the modified table
    }
};
int main()
{
    // Creating a custom locale with the changeDelimiter
    // facet
    cin.imbue(locale(cin.getloc(), new changeDelimiter));
    // prompt the user to enter the input with spaces
    cout << "Enter Input with Spaces: " << endl;
    string inputString;
    // Read input from cin, which has the modified locale
    cin >> inputString;
    // Print the input string
    cout << "Input Entered: " << inputString << endl;
