C Language Brief

As one of the most basic languages, C language is a powerful process-oriented language.

1 Process Control

C language Process Control is basically the same as all language flow control, but there are less details of the difference

Sequential Loop selection

2 functions

function is the main way to solve the problem in C language

Use functions to quickly and efficiently use code

Design and analysis in a modular format

3 hands

Pointer is address

Address is the number of units of memory

Pointer variables are variables that hold memory addresses

C language is its powerful pointer ability to handle a variety of hardware-related problems, extremely fast running speed is difficult to match other languages

4 Memory allocation

Memory allocation is a complex issue

Usually the operating system will allocate memory to the program to use, the program to handle this memory.

The memory of the static variable is controlled by the operating system and released on the stack

The memory of the dynamic variable is controlled by the program and finally released by the program Free (p) is located in the heap.
