The first lecture begins with the MFC "class"
Summary
This clarity will introduce the concept of "class" through a simple MFC application, then analyze its running mechanism and the basic MFC class hierarchy, and finally use the MFC Application Wizard provided by the project template to create a single document program TextViewer. . A simple MFC application
In the current "object-oriented" program, we often have heard the concept of "class" and "objects". So what is "class"? "Class" is essentially a new complex data type. Say it "new" because it is different from the basic data types such as char, int, float in the C language, saying it "complex" because it can not only contain various basic types of data, but also contain processing Data functions.
