Question

what’s wrong with this syntax? sorry for the newbie question.

source:

Level::Level()
{

    NintyDegreeDirections[4] =  
    { 
        1.0f, 1.4f, 2.4f, 0.1f
    }

...rest of class

header:

//all necessary includes

class Level
{
private:

    float NintyDegreeDirections[4];

...rest of header

how do I have an array as a instance member? I’m converting from C#

Answer 1

In the current version of C++ (C++11), you can initialize the member array like this:

Level::Level()
 : NintyDegreeDirections( { 1.0f, 1.4f, 2.4f, 0.1f } )
{
}

C++11 isn’t universally supported and if you don’t have support for this in your compiler you will have to assign to each member in turn.

E.g.:

NintyDegreeDirections[0] = 1.0f;
NintyDegreeDirections[1] = 1.4f;
//...
