谁能帮我解决这个C语言问题，我大大感谢

加上背景音乐，音乐的名字是music是wav的
我的程序代码是：
部分：

#include
#include
main()
{
system("color b");
printf("------------------------------------------------------------------------------\n");
printf(" | 1|四则运算 | \n");
printf(" | 2|面积运算 | \n");
printf(" | 3|体积运算 | \n");
printf(" | 4|关于本程序 | \n");
printf("------------------------------------------------------------------------------\n");
printf("您选择了:");
int number;
scanf("%d",&number);
switch(number)
{
case 1:
{
system("color a");
printf("-------------------------------------------------------------------------\n");
printf(" ！现在是四则运算模块 ！ \n");
printf(" | 1|加法 | \n");
printf(" | 2|减法 | \n");
printf(" | 3|乘法 | \n");
printf(" | 4|除法 | \n");
printf(" | 5|关于本模块 | \n");
printf("--------------------------------------------------------------------------\n");
printf("您选择了:");
int number2;
scanf("%d",&number2);
要求程序运行完之后音乐停止

很简单的：
#include
#include
#include
#pragma comment(lib, "WINMM.LIB")
main()
{
int number;
    system("color b");
PlaySound(TEXT("DOOR1.wav"),0,SND_FILENAME|SND_ASYNC);
    printf("------------------------------------------------------------------------------\n");
    printf("                    |  1|四则运算    |                                   \n");
    printf("                    |  2|面积运算    |                                   \n");
    printf("                    |  3|体积运算    |                                   \n");
    printf("                    |  4|关于本程序  |                                   \n");
    printf("------------------------------------------------------------------------------\n");
    printf("您选择了:");

    scanf("%d",&number);
    switch(number)
    {
    case 1:
        {
int number2;
            system("color a");
            printf("-------------------------------------------------------------------------\n");
            printf("                   ！现在是四则运算模块 ！                        \n");
            printf("                    |  1|加法    |                                \n");
            printf("                    |  2|减法    |                                \n");
            printf("                    |  3|乘法    |                                \n");
            printf("                    |  4|除法    |                                \n");
            printf("                    |  5|关于本模块    |                          \n");
            printf("--------------------------------------------------------------------------\n");
            printf("您选择了:");

            scanf("%d",&number2);
}
}

};因为是异步播放，所以PlaySound函数马上返回了，然后程序就结束了，资源就释放了

你这段简单到不知道怎么再简单的代码，和背影音乐这种高级应用，貌似很不搭边，就像小学生做十以内的加法要一个印有微分方程水印的作业本。且看大神怎么帮你完美解决这个非一般的需求。
