C++ User Input

C++ User Input

While cout is used to output data to the screen, cin is used to get user input from the keyboard.

Using cin

cin stands for "character input". It is used with the extraction operator >>.

#include <iostream>
using namespace std;

int main() {
  int age;
  cout << "Enter your age: ";
  cin >> age; // Get user input from the keyboard
  cout << "Your age is: " << age;
  return 0;
}

In the example above, the program waits for the user to type a number and press Enter. The entered number is then stored in the age variable.

Taking Multiple Inputs

You can also chain the >> operator to take multiple inputs at once:

int x, y;
cout << "Enter two numbers separated by space: ";
cin >> x >> y;
cout << "Sum: " << (x + y);

User input makes your applications dynamic and interactive!
