+## Input and Output
+
+* Input stream objects in C++ use 'cin'. This is used to save input data into the program.
+
+* Output stream objects use 'cout', as shown in the first introduction of C++, to print out statements to the console.
+
+```cpp
+#include <iostream>
+using namespace std;
+
+int main()
+{
+  int x;
+
+  cout << "Enter a number: " << endl; // Ask user for input
+  cin >> x; // Take user input
+  cout << "The output value of int x: " << x << endl;
+
+  return 0;
+}
+```
+
+* The header file `<iostream>` is required for stream objects.
+* After declaring a variable, using the `cin` object, input data can be saved into the variable.
+* The `cout` object prints the data saved into the variable to the console.
+
+
+The operators `<<` and `>>` are used to point in the direction of the data.
+* For `cin`, the `>>` operator is used. You can visualize the input data flowing into the variable.
+* For `cout`, the `<<` operator is used. You can visualize data from a string or variable flowing into the `cout` object.
