C中结构指针数组的内存分配

#include <stdio.h>
#include <stdlib.h>

struct Student {
    char name[20];
    int age;
};

int main() {
    int numStudents = 3;
    struct Student *studentArray[numStudents];

    // 动态分配内存
    for (int i = 0; i < numStudents; i++) {
        studentArray[i] = (struct Student *)malloc(sizeof(struct Student));
    }

    // 初始化指针数组
    for (int i = 0; i < numStudents; i++) {
        sprintf(studentArray[i]->name, "Student %d", i+1);
        studentArray[i]->age = 20 + i;
    }

    // 使用结构指针数组
    for (int i = 0; i < numStudents; i++) {
        printf("Student %d: Name - %s, Age - %d\n", i+1, studentArray[i]->name, studentArray[i]->age);
    }

    // 释放内存
    for (int i = 0; i < numStudents; i++) {
        free(studentArray[i]);
    }

    return 0;
}
