Question: Consider the sample code given below and answer the question that follows.
class SomeClass { int x; public: SomeClass (int xx) : x(xx) {} }; SomeClass x(10); SomeClass y(x);
What is wrong with the sample code above?
A
SomeClass y(x); will generate an error because SomeClass has no copy constructor

B
SomeClass y(x); will generate an error because SomeClass has no default constructor

C
SomeClass y(x); will generate an error because SomeClass has no public copy constructor

D
x(xx) will generate an error because it is illegal to initialize an int with that syntax

E
The code will compile without errors
