直接上示例了
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 | #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
", 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
1 2 3 4 5 6 7 8 9 10 11 12 13 | 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" },}; |
