I need to fix the errors that this code is giving me and also I neet to make it look better.

thank you!

void Delay(int duration[];int songLength){

}

Answer 1

Just make the delay function as given in the screenshot below :-

Joid Delay (int duration[], int songLength) { for(int i=0;i, songLength; i++){ duration[i]+200;
