Inspect the short function below. Assume timeCount is a global function from elsewhere in the code $($being global simply allows the variable to be accessed by this function 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$($buttonStane$)\{$

timeCount $=$ updateTime$()$;

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

$\}$

return timeCount;

$\}$

int

bool

float

long
