String Input and Output

In C++, you can read and write strings using the std::cin and std::cout objects from the iostream library.

To read a string from the user, you can use the std::getline function. This function reads a line of input until a newline character is encountered and stores it in a string variable.

Here's an example:

1#include <iostream>
2#include <string>
3
4int main() {
5  std::string input;
6
7  // Read string input from the user
8  std::cout << "Enter a string: ";
9  std::getline(std::cin, input);
10
11  // Print the input string
12  std::cout << "You entered: " << input << std::endl;
13
14  return 0;
15}

In this example, we declare a string variable input to store the user's input. We use std::getline to read a line of input from the user and store it in input. Finally, we use std::cout to print the input string.

You can try running this program and entering a string to see the result.

xxxxxxxxxx

#include <iostream>

#include <string>

​

int main() {

  std::string input;

​

  // Read string input from the user

  std::cout << "Enter a string: ";

  std::getline(std::cin, input);

​

  // Print the input string

  std::cout << "You entered: " << input << std::endl;

​

  return 0;
