This chapter describes most of the basic features of C + +: Built-in types, library types, class types, variables, expressions, statements, and functions.In this process, you will also briefly describe how to compile and run the program.To learn a new programming language, you must actually write the program. In this chapter, we will solve a simple data processing problem with the abbreviation program: A bookstore saves each transaction in a file format. Each transaction records the sales of a b

A constructor is a special member function that executes a constructor whenever a new object of the class type is created. The constructor works by guaranteeing that the data members of each object have the appropriate initial values. The constructor has the same name as the class name and cannot specify a return type. Like any other function, they can have no formal parameters, You can also define multiple parameters. Use an example to illustrate this.This constructor initializes the Units_sold

Here's a little trick to quickly add a lot of setters and getter: Right-click your class name and choose from the pop-up menu: "Source"-> "Generate getters and Setters"-> "Select All"-> " OK ".

Oracle's classic Oracle books: Oracle High performance tuning for 9i and 10g by Gavin Powell Book Description There are three parts to tuning a Oracle database:data modeling, SQL code tuning and physical database configuration. A data Model contains tables and relationships between tables. Tuning a data model involves normalization and de-normalization. Different approaches are required depending on the application, such as OLTP or a Data Warehouse. Inappropriate database design can make SQL co

/oracle/courses/dba/dba.htm 5. The teacher first gives examples of commonly used relational databases, such as SQL Server, DB2, Sybase, and Oralce, and also says that non relational databases are also useful, such as access that we know well. Then introduced the C/s structure, I think these people are familiar with, I will not repeat. 6. The teacher also recommended several reference books to learn from the DBA.
