C - 新的结构

Question

我正在尝试弄清楚如何使用 struct，但这段代码给我带来了很多错误。

#include <stdio.h>

int main(void)
{
    struct date
    {
        int today       =   6;
        int tomorrow    =   7;
        int threeDays   =   8;
    };

    struct date date;

    printf("%d", date.today);

    return 0;
}

Answer 1

struct date
{
    int today       =   6;
    int tomorrow    =   7;
    int threeDays   =   8;
};

struct date date;

您不能为结构类型分配默认值。

您可以做的是用正确的值初始化一个结构类型的对象:

struct date
{
    int today;
    int tomorrow;
    int threeDays;
};

struct date date = {6, 7, 8};
