why is {} placed after member initializer list in c++, although it is supposed to be empty ?

Question

class myclass{
public:
myclass(int a, int b, int c)
:var1(a),var2(b),var3(c)
{ // these curly braces.
} //these curly braces.
private:
int var1,var2,var3;
};

Answer 1

It's because when you define a function, it needs a body, the curly brackets is used to define the function body, even though it's empty
