C语言结构体初始化的三种方法

直接上示例了

#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;}

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"},};
