How to initialise a member array of class in the constructor?

Question

I am trying to do the following:

class sig
{
public:

int p_list[4];
}

sig :: sig()
{
p_list[4] = {A, B, C, D};
}

I get an error

missing expression in the constructor.

So how do I initilalise an array?

Answer 1

In C++11 only:

class sig
{
    int p_list[4];
    sig() : p_list { 1, 2, 3, 4 }   {   }
};

Pre-11 it was not possible to initialize arrays other than automatic and static ones at block scope or static ones at namespace scope.
