C++ User Input

In C++, you can take user input using the cin object, which is part of the iostream library.

Example: how to take input from the user

#include <iostream>
using namespace std;

int main() {

    string name;

    // Asking for the user's name
    cout << "Enter your name: ";
    cin >> name; // Taking input for the name

    // Displaying the collected information
    cout << "Hello, " << name  << endl;

    return 0;
}

Explanation:

• cin is used to take input from the user.
• cout is used to output information to the screen.

Output:

Example: enter your age

#include <iostream>
using namespace std;

int main() {

    int age;

    // Asking for the user's age
    cout << "Enter your age: ";
    cin >> age; // Taking input for the age

    // Displaying the collected information
    cout << "Your age is " << age  << endl;

    return 0;
}

Output:
