C语言编程，从基础到高级c

C语言，作为一门广泛使用的编程语言，以其简洁性、高效性和灵活性而闻名，它不仅在底层系统编程中占据重要地位，还在应用层开发中发挥着重要作用，本文将从C语言的基础知识到高级特性,全面介绍其编程逻辑和应用场景。

C语言的基础知识

C语言是一种结构化的编程语言，支持函数、指针、结构体等高级特性，其基础包括关键字、变量、数据类型、运算符和控制结构。

1. 关键字：C语言有32个关键字，如int、float、char、void等，这些关键字用于定义变量、函数和结构体等。

2. 变量：变量用于存储数据，在C语言中,变量必须声明后才能使用。

   int a;  // �·声明一个整型变量a
   char b; // ················································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································
