12.1 Storage Class Storage Period: the time when the variable is stored in the memory. The scope and link of the variable indicate which parts of the program can use the variable name.Different storage classes provide variable scopes, links, and

Chapter 10 objects and Classes Mountains and waters finally come to the front of the class. This chapter begins and will finally be in touch with the class at zero distance.   OOPHow designers think When using procedural programming methods,

I heard an example about inline in the class about the efficiency of inline function execution. After class, I wrote a record based on my memories. It can be seen that the execution efficiency of inline functions is indeed higher than that of common

1. Write a program that requires the user to enter two integers, and the giant program calculates and outputs the and output of all integers (including these two integers) between the two integers. This assumes that you first enter a smaller integer,

1: indicates that the compiler contains all information in the stdio. h file.2. parentheses indicate that main () is a function name. int indicates that the function returns an integer. void indicates that the function does not accept any parameters.

1. C language refreshes the output buffer in three cases: the buffer zone is full, and line breaks and inputs are encountered. 2. in C language, the compiler can select which parameter value in the function is calculated first, which improves the
