User Input
As we have already discussed earlier cin is used to get user input. This is paired along with the extraction operator (>>)
The following example reads a value from the user and prints it on the screen.
Example:
#include <iostream>
using namespace std;
int main()
{
int num;
cout << "Type a number: "; // displayed on the screen
cin >> num; //value taken from User
cout << "Your number is: " << num; // number displayed on the screen
return 0;
}
