我一直在研究一个让机器人跟随声音的程序，但我不断收到奇怪的编译器错误。我猜我犯了一些错误，使编译器脱离了轨道。

#define TICKS_TO_SAMPLE 6
#define MS_TO_SAMPLE 100
#define TIME_TO_QUIET 250
#define ONE_THIRD 480
#define SAMPLE_DEPTH 20
#define NUM_OF_MOVEMENTS 6
#define TIME_MOVING 1000
#define MIC SENSOR_1

int gauge()
{
int soundMax = 0;
for(int tick = 0; tick < TICKS_TO_SAMPLE; tick++){
    if(MIC > soundMax){
        soundMax = MIC;
    }
    Wait(MS_TO_SAMPLE);
}
return soundMax;
}

int soundFind(int width)
{
int firstMax = 0;
firstMax = gauge();
OnFwd(OUT_A, 75);
Wait(width);
Off(OUT_AC);
Wait(TIME_TO_QUIET);
int secondMax = 0;
secondMax = gauge();
OnRev(OUT_A, 75);
Wait(width*2);
Off(OUT_AC, 75);
Wait(TIME_TO_QUIET);
int thirdMax = 0;
thirdMax = gauge();
if(firstMax >= secondMax && firstMax >= thirdMax)
{
    OnRev(OUT_A, 75);
    Wait(width);
    Off(OUT_AC);
    Wait(TIME_TO_QUIET);
}
else
    {
    if(secondMax >= firstMax && secondMax >= thirdMax)
    {
        OnRev(OUT_A, 75);
        Wait(width*2);
        Off(OUT_AC);
        Wait(TIME_TO_QUIET);
    }
}
if(width > SAMPLE_DEPTH)
{
    return width/3;
}
else{
    return 0;
}
}
task main()
 {
 int startingAngle = ONE_THIRD;
 SetSensorSound(IN_1);
 for(int movements = 0; movements < NUM_OF_MOVEMENTS; movements++){
    startingAngle = soundFind(ONE_THIRD);
    while(startingAngle > SAMPLE_DEPTH)
    {
     startingAngle = soundFind(ONE_THIRD);
    }
    OnRev(OUT_AC, 75);
    Wait(TIME_MOVING);
    Off(OUT_AC);
}
}

吐出来

line 32 Error: ')' expected
line 32 Error: ';' expected

和

Error: Unmatched close parenthesis

在第 32、33、35-39、40、45-48、51、58、60-64、66-68 行

该Off()函数只接受一个参数，电机端口。您正在尝试将功率值作为第二个参数传递。
