C + + has richer content and strict type checking, such as a few grammatical things, the idea of object-oriented (object) thinking, as well as the concept of the template. Of course, C + + can also be process-oriented programming.The C language rule

It is required to define a function from the outside and change the value of C in the main function. Steps: 1. Call a function. If you want to modify the value of the variable in the main function externally, you need to pass the address of this
