About this program
This is an example program in c basic example programs. Read the concept first: C++ Programming Structure, then study the code and output below.
Definition of Cin
The cin read input from the keyboard. The cin is the stream extraction operator (>>), which is mainly used for reading the input from the console.
Unlike C, cin reads all data types without any notation.
