C语言构造函数返回值struct的探索

2014-12-31

研究一个对象，我们先要来了解它

关于struct的定义

A struct in the C programming language (and many derivatives) is a complex data type declaration 

that defines a physically grouped list of variables to be placed under one name in a block of memory,

struct 在c语言家族里是一个复杂数据类型声明，定义一个内存块并放置在一个物理分组名称的变量列表里

但是仅靠文字理解是不行的，我们还需要去实践它

#include <stdio.h>#include <stdlib.h>#include <string.h>typedef struct BuySome{char name[100];int price;} Drink;Drink get(){Drink Coke;char *name= Coke.name;printf("entery name:\n");scanf("%s",name);strcpy(Coke.name, name);printf("entery price:\n");scanf("%d",&Coke.price);// strcpy(Coke.name, "Coca Cola");// Coke.price = 5;return Coke;}int main(int argc, char const *argv[]){Drink Coke;Coke = get();printf("I bought %s the price is |%d| yuan.\n", Coke.name, Coke.price);return 0;}
