(OwO)電腦圖學week15_5/31

 更詳細解說PlaySound()

#include<mmsystem.h>上週教的

PlaySound("檔名.wav",NULL,SND_ASYNC);///上週

本周教#include<windows.h>
PlaySound("107042111.wav",NULL, SND_SYNC);

開一個empty file存成week15-1.cpp

#include <windows.h>

#include <stdio.h>

int main()

{

    printf("PlaySound()之前\n");

    ///檔案不存在會有錯誤聲音

   PlaySound("107042111.wav",NULL, SND_SYNC);

   printf("PlaySound()之後\n");

}

Setting ->Compiler Setting->Linker加入winmm
