c语言结构体指针数组怎么初始化

在C语言中，结构体指针数组的初始化可以通过以下几种方式进行：

1. 逐个初始化：通过逐个为每个元素赋值。例如：

struct Person {     char name[20];     int age; };  struct Person *people[3];  people[0] = malloc(sizeof(struct Person)); strcpy(people[0]->name, "Tom"); people[0]->age = 20;  people[1] = malloc(sizeof(struct Person)); strcpy(people[1]->name, "Jerry"); people[1]->age = 25;  people[2] = malloc(sizeof(struct Person)); strcpy(people[2]->name, "Alice"); people[2]->age = 30; 

2. 使用静态初始化：通过静态方式初始化每个元素。例如：

struct Person {     char name[20];     int age; };  struct Person *people[3] = {     &(struct Person){"Tom", 20},     &(struct Person){"Jerry", 25},     &(struct Person){"Alice", 30} }; 

3. 使用循环初始化：通过循环为每个元素赋值。例如：

struct Person {     char name[20];     int age; };  struct Person *people[3]; char names[3][20] = {"Tom", "Jerry", "Alice"}; int ages[3] = {20, 25, 30};  for (int i = 0; i < 3; i++) {     people[i] = malloc(sizeof(struct Person));     strcpy(people[i]->name, names[i]);     people[i]->age = ages[i]; } 

需要注意的是，在使用完结构体指针数组后，需要手动释放内存。
