Inspect the short function below. Assume time Count is a global function from elsewhere in the code $($being global simply allows the variable to be accessed by this functior freely$).$

Based on the working code below $($and what you know about functions$),$ what type must the variable timeCount be$?$

long startTimer$()\{$

int buttonState $=$ digitalRead$($buttonPin$)$;

while$($buttonState$)\{$

timeCount $=$ updateTime$()$;

buttonState $=$ digitalRead buttonPin
