scan line in c++

Sure! Here is a response:

#include <iostream>
#include <string>
using namespace std;

int main() {
    string line;

    cout << "Enter a line of text: ";
    getline(cin, line);

    cout << "You entered: " << line << endl;

    return 0;
}

Explanation: - We start by including the necessary header files for input/output and string manipulation. - Inside the main function, we declare a variable line of type string to store the input. - Then, we prompt the user to enter a line of text using the cout statement. - We use the getline function to read the entire line of text entered by the user, and store it in the variable line. - Finally, we output the entered line of text using the cout statement and the variable line. - The program then returns 0 to indicate successful execution.
