Question

怎么在VS编的程序中，C++语言，播放音频文件

Answer 1

用playsound函数。选项见：
http://msdn.microsoft.com/en-us/library/windows/desktop/dd743680(v=vs.85).aspx
例如：
#include <stdio.h>
#include <windows.h>
#include <mmsystem.h>
#pragma comment(lib, "winmm.lib")

void main()
{
PlaySound(TEXT("recycle.wav"), NULL, SND_FILENAME);

while (1)
{
printf("program is running... here\n");
Sleep(1000);
}
exit(0);
}

追问

那些头文件都需要放在项目的哪些目录？

追答

应该是放在编译程序的的文件夹里。头文件一般都在一个文件夹里。

Answer 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int a[5];
    int i,j,k;
    for(i=0;i<=4;i++)
	{
		scanf("%d",&a[i]);
	}

	for(i=0;i<=4;i++)
	{
		for(j=0;j<=4;j++)
		{
			if(a[i]>a[j])
			{
				k=a[i];	a[i]=a[j];	a[j]=k;
			}
		}
	}

	printf("еепР╫А╧Шйгё╨\n");

	for(i=0;i<=4;i++)
	{
		printf("%d\t",a[i]);
	}
    return 0;
}

Answer 3

C++语言中播放音频文件的方法如下：
1：Playsound函数
事例代码如下
#include<windows.h>
#include<stdio.h>
#pragma comment(lib,"WinMM.Lib")
void main()
{
PlaySound("c:\\dui12.wav",NULL,SND_FILENAME|SND_ASYNC);
}
2:和Playsound函数类似的undplaysound函数
#include<windows.h>
#include<stdio.h>
#pragma comment(lib,"WinMM.Lib")
void main()
{
undPlaySound("c:\\dui12.wav",NULL,SND_FILENAME|SND_ASYNC);
}
3：功能强大的函数，支持混音的MCI类
事例代码如下
#include<windows.h>
#include "mmsystem.h"//导入声音头文件
#pragma comment(lib,"winmm.lib")//导入声音头文件库
#include<stdio.h>
void PlayMp3() ;
void main()
{
PlayMp3() ;
PlaySound("C:\\Normal2.wav", NULL, SND_FILENAME | SND_ASYNC | SND_LOOP);

system("pause");

}
void PlayMp3()
{
char buf[128];
char str[128] = {0 };
int i = 0;

//use mciSendCommand
MCI_OPEN_PARMS mciOpen;
MCIERROR mciError;
//SetWindowText(NULL,"12345");
mciOpen.lpstrDeviceType = "mpegvideo";
mciOpen.lpstrElementName = "c:\\WELCOME.WAV";
mciError = mciSendCommand(0,MCI_OPEN,MCI_OPEN_TYPE | MCI_OPEN_ELEMENT,(DWORD)&mciOpen);
if(mciError)
{
mciGetErrorString(mciError,buf,128);
printf("send MCI_OPEN command failed:%s\n",buf);
return;
}
UINT DeviceID = mciOpen.wDeviceID ;
MCI_PLAY_PARMS mciPlay;

mciError = mciSendCommand(DeviceID,MCI_PLAY,0 ,(DWORD)&mciPlay);
if(mciError)
{
printf("send MCI_PLAY command failed\n");
return;
}
}
