C++ User Input
C++ User Input
You have already learned that cout is used to output (print) values. Now we will use cin to get user input.
cin is a predefined variable that reads data from the keyboard with the extraction operator (>>).
Example
#include <iostream>
using namespace std;int main() {
int x;
cout << "Type a number: "; // Type a number and press enter
cin >> x; // Get user input from the keyboard
cout << "Your number is: " << x;
return 0;
}
Output:
Type a number: [Type number with your keyboard]
OUTPUT: [YOUR TYPED NUMBER]
cout is pronounced "see-out". Used for output, and uses the insertion operator (<<)
cin is pronounced "see-in". Used for input, and uses the extraction operator (>>)
