.h 声明文件

// MyFunction.h

// C7_结构体多文件

// Created by dllo on 15/7/8.

#import <Foundation/Foundation.h>

// .h文件, 我们写函数的声明

// .m文件,写函数的定义

// 声明一个学生类型的结构体,用typedef设置

struct student{

int stuAge;

float stuScore;

char stuSex;

char stuName[20];

};

typedef struct student Student;

struct test{

int a;

int b;

char str[17];

int c;

};

typedef struct test Test;

// 打印学生类型变量的所有内容

void printStu(Student stu);

//找到三个学生成绩最好的人,并且把这个人返回

Student maxScore(Student stu1,Student stu2,Student stu3);

// 找学生平均年龄

int avgStuAge(Student stu1,Student stu2,Student stu3);

// 定义一个关于坐标的结构体

struct Cpoint{

int x;

int y;

};

typedef struct Cpoint CPoint;

// 1.判断两个点是否在一个水平线上,返回BOOL

BOOL horizontalRule(CPoint p1,CPoint p2);

// 2.判断垂直

BOOL vertical(CPoint p1,CPoint p2);

//3.判断是否相等

BOOL samePoint(CPoint p1,CPoint p2);

// 判断一年的第几天

struct days{

int year;

int month;

int day;

};

typedef struct days Days;

// 根据年月日,计算第几天

int dayOfYear(Days day);

// 通过函数,对学生类型的结构体数组,进行冒泡排序

void bubbleSortStu(Student stu[],int count);

// 找到及格的学生的个数

int passTestStu(Student stu[],int count);

// 找到姓名的首字母是l的人数

int initialName(Student stu[],int count);

// 结构体的嵌套使用

struct clssRoom{

char roomName[20]; // 房间名

Student stu;

};

struct school{

char schoolName[20];

struct clssRoom room;

};
