Question

I was wondering if anyone could spot what is wrong with my structure declaration and use. At the moment I have a structure and wish to store float array as one of it’s members.

My code:

struct Player{ float x[12]; float y[12]; float red,green,blue; float r_leg, l_leg; int poly[3]; bool up,down; }; 

I then tried filling the struct:

float xcords[12] = {1,1,1,1,1,1,1,1,1,1,1,1 }; float ycords[12] = {1,1,1,1,1,1,1,1,1,1,1,1 }; Player player = {xcords,ycords,1,1,1,2,2,true,true}; 

Error:

Answer 1

Arrays decay to pointer-to-first-element of the array in most contexts as is the case with xcords and ycords. You cannot initialize the struct like this. So, you have to initialize the members explicitly:

Player player = {         {1,1,1,1,1,1,1,1,1,1,1,1 }, // xcords         {1,1,1,1,1,1,1,1,1,1,1,1 }, // ycords         1,1,1,                      // red, green, blue         2,2,                        // right, left         {0,1,2},                    // poly[3]   -- missing?                   true,true};                 // up, down 

You are also missing initializers for poly[3] if I understand correctly. Put in the appropriate values. Otherwise there will be default initialization — is that what you want?
