c++ question (total of 2 questions) Thanks!

What is wrong with the following program? #include int what_is_2x281() { int x, y = 281; return x + y; int main() { std::cout "What is 2 x 281? " void print_an_integer(int x) { std::cout > x; print_an_integer(x); A. this code does not compile because x is an uninitialized value B. main() must have a return statement C. print_an_integer() takes an int but is called with a size_t, which may cause loss of precision D. size_t is not a valid type E. nothing is wrong with this program
