What is wrong with the following program?

#include

void takes$\_$an$\_$integer$($int x$)\{\}$

int main$()\{$

size$\_$t x;

std::cin $>>$ x;

takes$\_$an$\_$integer$($x$)$;

$\}//$ main$()$

Group of answer choices

The code does not compile because takes$\_$an$\_$integer$()$ has an empty definition.

main$()$ must have a return statement

print$\_$an$\_$integer$()$ takes an int but is called with a size$\_$t$,$ which may cause loss of precision

size$\_$t is not a valid type

nothing is wrong with this program
