三种初始化结构体的方式

struct_initializer.m

struct student{
    const char *name;
    int age;
    char tag;
};

int main(int argc, const char * argv[]) {
    // 方式一
    struct student st_student1 = {"Alan",10,'1'};
    
    // 方式二
    struct student st_student2 = {
        .name = "梁杰",
        .age = 20,
        .tag = '0'
    };
    
    // 方式三 Xcode 中不允许这种方式
    struct student st_student3 = {
        name:"pmst",
        age:23,
        tag:'-1'
    };
    return 0;
}
