How to read input from the console in C++?

 In C++, you can read input from the console using the std::cin object, which is part of the C++ Standard Library. Here's an example of how to use std::cin to read input in C++:

c++
#include <iostream>

int main() {
    std::string name;

    std::cout << "Enter your name: ";
    std::cin >> name;

    std::cout << "Hello, " << name << "!" << std::endl;

    return 0;
}

In this example, we use std::cin to read a string from the console and store it in the variable name. The >> operator is used to extract input from the input stream and insert it into the variable.

You can also use std::cin to read other types of data, such as numbers or characters. For example:

c++
#include <iostream>

int main() {
    int x;
    double y;
    char c;

    std::cout << "Enter an integer: ";
    std::cin >> x;

    std::cout << "Enter a double: ";
    std::cin >> y;

    std::cout << "Enter a character: ";
    std::cin >> c;

    std::cout << "You entered: " << x << ", " << y << ", " << c << std::endl;

    return 0;
}

In this example, we use std::cin to read an integer, a double, and a character from the console, and store them in the variables x, y, and c, respectively. We then use std::cout to print the values of these variables to the console.
