We already know how to output the data with the object `cout` and operator `<<`. However, sometimes we need to get values directly from the user. To enable this operation use `cin` in combination with the extraction operator `>>`.

```
cin >> x; // Get the value for the variable x
```

For example, here we want to get the value for the variable a and output it:

01   #include <iostream>
 02   using namespace std;
 03   
 04   int main() {
 05       // Declare the variable
 06       int a;

 07       // Print the message for user to get the value
 08       cout << "Print a number: ";

 09       // Get user input
 10       cin >> a;

 11       // Display the input of the user
 12       cout << "Your number is: " << a;
 13 
 14       return 0;
 15   }

In the **line #9** the user print the value which will be stored in the variable `a`.
