[NXC] random playtone

有趣的小程式, 隨機產生1~6後發出不同音高。 ========================================= task main() { int a = 0; while(true){ a = Random(5)+1; NumOut(20,20,a); switch(a) { case 1: { PlayTone(a*300, 40); Wait(500);break; } case 2: { PlayTone(a*300, 40); Wait(500);break; } case 3: { PlayTone(a*300, 40); Wait(500);break; } case 4: { PlayTone(a*300, 40); Wait(500);break; } case 5: { PlayTone(a*300, 40); Wait(500);break;} case 6: { PlayTone(a*300, 40); Wait(500);break;} default: { break;} } }//while }
