iOS 结构体struct就是这么简单

结构体的定义

// 结构体类型名 StudentScore

struct StudentScore {

int stuNo;

int stuMath;

int stuEnglish;

int stuChinese;

};

// 创建stu结构体信息

struct StudentScore st1 = {1, 98, 96, 87};

// 结构体值的调用

NSLog(@"st1:%d,%d,%d,%d",st1.stuNo,st1.stuMath,st1.stuEnglish,st1.stuChinese);

可以用typedef 来定义struct

// 使用typedef来定义结构体

typedef struct StudentScore2 { // 此处的StudentScore2可以直接删除不写

int stuNo;

int stuMath;

int stuEnglish;

int stuChinese;

} studentScore2;

studentScore2 st2 = {2, 95, 88, 98};

NSLog(@"st2:%d,%d,%d,%d",st2.stuNo,st2.stuMath,st2.stuEnglish,st2.stuChinese);
