Reading User Input with cin

Reading User Input with cin

The cin object reads input from the keyboard. The >> operator extracts value from cin and stores it in the variable on the right. This allows interactive programs that respond to user input.

cpp
#include <iostream>
using namespace std;
 
int main() {
    int age;
    cout << "Enter your age: ";
    cin >> age;
    
    cout << "You entered: " << age << endl;
    return 0;
}
