argument of a parameterized constructor

Question

can someone explain me how's the argument passed in the 1st parameterized constructor working?

public:
//Constructors
Bigint();
Bigint(long long); // 1st parameterized constructor
Bigint(std::string); // 2nd parameterized constructor.

What do you mean by "return type"? Constructors have no return type. — Emil Laine, Apr 03 '16 at 15:50
long has been written twice which is confusing since we usually write return type of any variable once. — Taimoor Mirza, Apr 03 '16 at 16:09

long long is a type, just like int or long. But the difference is that it's at least 64 bits wide.
