When we write functional scripts, we tend to place functions that are similar in operation or similar in parameters into the same shell script, which is easy to manage, easy to maintain, and clear. In this case, the usual approach is to define all

function allows us to divide a complex function into several modules, which makes the program structure clearer and the code reuse more efficient. Like other programming languages, the Shell supports functions as well. The Shell function must be

Pointers are a widely used data type in the C language. The use of pointer programming is one of the most important styles of C language.Pointer variables can be used to represent various data structures, easy to use arrays and strings, and can be
