#include <stdio.h>struct student_st{ char c;
int score;
const char *name;
};static void show_student(struct student_st *stu)
{ printf("c = %c, score = %d, name = %s\n", stu->c, stu->score, stu->name);
}int main(void)
{ // method 1: 按照成员声明的顺序初始化
struct student_st s1 = {'A', 91, "Alan"};
show_student(&s1);
// method 2: 指定初始化,成员顺序可以不定,Linux 内核多采用此方式
struct student_st s2 =
{
.name = "YunYun",
.c = 'B',
.score = 92,
};
show_student(&s2);
// method 3: 指定初始化,成员顺序可以不定
struct student_st s3 =
{
c: 'C',
score: 93,
name: "Wood",
};
show_student(&s3);
return 0;
}</stdio.h> |
运行结果:
如果想初始化结构体数组,可采用 {{ }, { }, { }} 方式,如

struct student_st stus[2] =
{ {
.c = 'D',
.score = 94,
/*也可以只初始化部分成员*/
},
{
.c = 'D',
.score = 94,
.name = "Xxx"
},
}; |
