c - 为结构变量赋值

Question

结构类型定义为:

typedef struct student{
    int id;
    char* name;
    double score;
} Student;

我构造了一个 Student 类型的变量，我想为其赋值。我怎样才能有效地做到这一点？

int main(){
    Student s1;

    int id = 3;

    char* name = getName(id);

    double score = getScore(id);

    /*Error
    s1 = {id, name, score};
    */

    /*  Can I avoid assigning values individually?
    s1->id = id;
    s1->name = name;
    s1->score= score;
    */

    return 0;
}

Answer 1

在 C99 标准中，您可以使用复合文字来赋值:

Student s1;
s1 = (Student){.id = id, .name = name, .score = score};
