read full line in c++

To read a full line in C++, you can use the getline() function from the <iostream> library. Here's an example of how to use it:

#include <iostream>
#include <string>

int main() {
    std::string line;
    std::cout << "Enter a line of text: ";
    std::getline(std::cin, line);
    std::cout << "You entered: " << line << std::endl;
    return 0;

Let's break down the steps involved in this code:

  1. Include the necessary headers: cpp #include <iostream> #include <string>
  2. The <iostream> header provides input/output functionality.
  3. The <string> header provides the std::string class for working with strings.

  4. Declare a variable to store the line of text: cpp std::string line;

  5. We create a std::string variable named line to store the input.

  6. Prompt the user for input: cpp std::cout << "Enter a line of text: ";

  7. The std::cout statement displays the prompt message to the user.

  8. Read the line of text using getline(): cpp std::getline(std::cin, line);

  9. The std::getline() function reads a line of text from the standard input (in this case, std::cin) and stores it in the line variable.

  10. Display the input: cpp std::cout << "You entered: " << line << std::endl;

  11. The std::cout statement outputs the entered line of text along with a message.

  12. Return 0 to indicate successful program execution: cpp return 0;

That's it! This code will allow you to read a full line of text in C++ using the getline() function.
