User Input
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
08 // Print the message for user to get the value
09 cout << "Print a number: ";
10
11 // Get user input
12 cin >> a;
13
14 // Display the input of the user
15 cout << "Your number is: " << a;
16
17 return 0;
18 }
In the line #12 the user print the value which will be stored in the variable a
.
