函数如何创建结构体? [英] How can a function create a struct?

问题描述

我在 C 编程课程中的一项作业是定义一个名为 create_card 的函数.该函数接收一个花色字符和一个卡片值，并返回一个 card_t 结构体.

One of my assignments for the C Programming course was define a function called create_card. This function receives a suit character and an a card value, and returns a card_t struct.

问题:函数应该如何创建结构体?它不能只为结构创建值吗?是我误解了问题的意思还是作业写错了?

Question: How is a function supposed to create a struct? Can't it only create values for the struct? Did I misinterpret the meaning of the question or was the assignment written down wrong?

推荐答案

这是一个返回结构体的函数示例.

This is an example of a function returning a struct.

struct test {
    int a;
};
struct test Fun(int k) {
    struct test d;
    d.a=k;
    return d;
}

将 struct test 替换为您的结构名称，并将 struct test 的定义替换为您的结构定义.

Replace struct test with the name of your struct and the definition of struct test with your struct's definition.

如何使用

int main() {
    struct test Test=Fun(6);
    printf("%d",Test.a); // prints '6'
    return 0;
}
