C语言结构体定义、声明与初始化详解.pdfVIP

结构体变量及Ⅰ

•structpoint{

intx;

inty;

};

structpointpoint1,point2;/*变量*/

point1.x=10;point2.y10;/*.,成员*/

point2.x=5;point2.y0;

结构体变量及Ⅱ

•structbirth{

intyear,month,day;

}date;

date.year=2000;

date.month=12;

date.day=1;

结构体变量及Ⅲ

•struct{

charname[20];

structbirthdate;

intno;

floatenglish,math,aver;

}student;

student.no=111;student.date.year=1999;

strcpy(student.name,”lu”);

结构体变量的初始化Ⅰ

•structbirth{

intyear,month,day;

}date={2000,12,1};

结构体变量的初始化Ⅱ

•structstudent{

charname[20];

structbirthdate;

intno;

floatenglish,math,aver;

}stud={“lu”,{2000,12,1},111,99.0,80.0,0.0};

结构数组

•structstudent{

charname[20];

structbirthdate;

intno;

floatenglish,math,aver;

};

structstudentclass[60];

class[i].no=111,class[i].english=99.0;

练习

•输入n个学生的,学号,英语成绩,按英语

成绩的降序排序输出.

•结构体赋值

class[i]=class[j]Exp14_1.cpp

结构和指针Ⅰ

•指向结
