Multi-file structure and compilation preprocessing commands1. General organizational structure of C + + programsTypically, a project is divided into at least three files: a class definition file (*.h file), a class implementation file (*.cpp file),

source program → External declarations | Sub-Program (external Declaration)External declarations → Function definitions | function declarationfunction definition → type identifier (compound sentence)identifier type → no type | Character Type |

If statements process two branches, the IF-else-If structure must be used when processing multiple branches. However, if there are many branches, the more nested if statement layers,ProgramIt is not only huge but also difficult to understand.
