In this tutorial, we will explore two important concepts in C programming: typedef and enum. Both typedef and enum are used to make code more readable, maintainable, and less error-prone, which is essential in
Enum的作用就是把一串名字和一串整型联系在一起, 可以说在c中Enum完全可以被#define取代, 比较鸡肋的 enum sizes { small=7, medium, large=10, humungous }; 如果不赋值, 会从0开始递增, 或从赋的值开始递增 Enum一个优点, 便于debug There is one advantage to enums: unlike #defined names which are ...
Use of typedef enum in C We can use the typedef and enum together in C programming. If we use typedef with enum in C then it increases the code readability and creates a new type for the enum. Let see an example, where I am creating a list of errors using the enum and defining a...
system("pause"); } 二、枚举类型(限定取值) 枚举常量实质是整型数据 #include<stdio.h>#include<stdlib.h>//枚举的一般形式,限定在这个范围内取值//如果没有一个赋初值,就会从0循环到最后一个,每次加1//如果第一个赋初值,后面每个加1//除非自己赋值,否则计算机赋值会让每个枚举常量都不同enumlevel{ 司令=...
extern "c" 包含双重含义,从字面上即可得到:首先,被它修饰的目标是“extern”的;其次,被它修饰的目标是“C”的。 extern的意思通过上面的解释, 应该是很明白了, 那么C什么意思 这个就要谈起C和C++的混合编译, 重要的是C和C++编译器对变量名的改写方式是不同的 ...
enum mips_special_regs { gp(28), fp(30), sp(29), ra(31); private final int register; mips_special_regs(int r) { register = r; } public int reg() { return register; } } … int n = mips_special_regs.fp.reg(); As noted in Section 3.5.2, Pascal and C do not allow the...
The syntax of typedef in C is </> Copy typedef <type> identifier where type– existing datatype identifier– new name to the datatype typedef can be used with struct, union, enum, function pointers. Example </> Copy typedef int MARK; ...
red, white, black, green, color_num, } color_t; int main (void) { enum ...
All of the considerations we explored for enums equallyapply tostructs.We will go through each of them as they apply to structs. Before we examine the use of typedef with structs, we must first complete the picture of using structs. In the last chapter, Chapter 9, ...
