Introduction to CC language structure is extremely compact, C language is a modular programming language, the entire program can be divided into several relatively independent function modules, mutual calls between modules and data transfer is very convenientC language is very powerful in its expressive ability. The C language takes into account the features of high-level languages and assembly language, as well as direct access to hardware functions

function is the basic function unit of C++/C program, its importance is self-evident. The subtle drawbacks of a function design can easily cause the function to be used incorrectly, so it is not enough to make the function correct. This chapter focuses on the interface design of functions and some rules of internal implementation. The two elements of a function interface are parameters and return values. In C, the parameters of a function and the return value are passed in two ways: value passin
