C + + programs can be defined as collections of objects that interact by invoking methods of each other. Now let's briefly look at what classes, objects, methods, and immediate variables are. Object- object has state and behavior. For example:

The program refers to LNZ001 's blog notes, link address: http://blog.csdn.net/LNZ001/article/details/54851551.Because of their weak foundation, so they quoted the online program. The program includes character processing, word processing, and text
