Question

I have created two structs called PERSON and DATE

我想在特定行添加音乐，我了解为了做到这一点我需要有windows.h。唯一的问题是，当我添加此头文件时，我的两个DATE结构函数中出现一堆C2223错误。他们都说

"left of '->month' must point to struct/union   structs"

这里是错误所在的函数

oid getDate(DATE *d)
{
    printf("\nEnter the year: ");
    scanf("%i", &d->year); //the errors are with lines like these
    while (d->year > 2018 || d->year < 1890)
    {
        printf("Thats not a valid option, try again\n");
        printf("\nEnter the year: ");
        scanf("%i", &d->year);
    }

    printf("\nEnter the month: ");
    scanf("%i", &d->month); //pass by reference d->value or *d.value
    while (d->month > 12 || d->month <= 0)
    {
        printf("Thats not a valid option, try again\n");
        printf("\nEnter the month: ");
        scanf("%i", &d->month);
    }

    printf("\nEnter the day: ");
    scanf("%i", &d->day);
    while (d->day > 31 || d->day <= 0)
    {
        printf("Thats not a valid option, try again\n");
        printf("\nEnter the day: ");
        scanf("%i", &d->day);
    }

    while ((d->month == 2) && ((d->year % 4) == 0))
    {
        if (d->day > 28)
        {
            printf("Thats not a valid date for a leap year, try again\n");
            printf("\nEnter the day: ");
            scanf("%i", &d->day);
        }
        else
        {
            break;
        }
    }

}
void displayDate(DATE *d) {
    printf("%02i/%02i/%004i", d->month, d->day, d->year); // %2i means a width of 2. The 0 is just a place holder // for a single digit date printf("\n");
}

我不熟悉windows.h的工作方式，我需要删除*吗？

Answer 1

我自己解决了问题，因为似乎没人知道。

发生的事情是windows.h已经包含一个DATE结构，所以我不得不将我的DATE结构重命名为DNTE之类的东西，并且工作得很好。

对于那些想知道如何添加音乐的人，只需添加

除了bool y[5];和char y[5];

，您必须先打开它，然后像文件一样播放它。所以

#include <windows.h>
#pragma comment(lib, "Winmm.lib")

添加<windows.h>时出现结构错误
