void play_music();//奏乐

    puts ("happy birthday!\n");
   
    play_music();
   
    return 0;

    }
void play_music()

{
   
    int i=0;
   
    for(;i<25;++i)

{
    Beep(rhythm[i]*5,delay[i]);
   
    if(i==24)
   
    {
        Sleep(500);
        
        i=0
    ;}
        }   
}

那要如何改正

{

    puts ("happy birthday!\n");
   
    play_music();
   
    return 0;

    }
我记得编译的时候，是说这里的函数返回值错了
