1.结构体--许多东西比较复杂具有许多属性，无法简单描述，需借助结构体来定义属性

关键字 struct

​

#include<stdio.h>
struct game
{
  char name[20];
  short price;
};
int main()
{
  struct game a1 = { "战地5",5 };
  printf("游戏名：%s\n", a1.name);
  printf("价格：%d元\n", a1.price);
  a1.price = 15;
  printf("修改后的价格：%d\n", a1.price);
  return 0;
}


利用指针进行简化代码

#include<stdio.h>
struct game
{
  char name[20];
  short price;
};
int main()
{
  struct game a1 = { "战地5",5 };
  struct game* pa = &a1;
  printf("游戏名：%s\n",pa->name);
  printf("价格：%d元\n",pa->price);
  return 0;
}

2.strcpy字符串拷贝，库函数

​

#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>
#include<string.h>//头文件
struct game
{
  char name[20];
  short price;
};
int main()
{
  struct game a1 = { "战地5",5 };
  strcpy(a1.name, "战地2040");
  printf("%s\n", a1.name);
  return 0;
}
