i image i can add something like this:
pieces.h:
TetrisPieces TetrisPiecesByIndex[7];

pieces.cpp:
TetrisPiecesByIndex = {
Pieces.I,
Pieces.O
......
};

but it says:

A type specifier is required for all declarations
misty socket
#

ok, so this is the data structure i came up with
(i should not be allowed to code)

pieces.h:


extern struct TetrisPieces {
    int I[3][2];
    int O[3][2];
    int S[3][2];
    int Z[3][2];
    int L[3][2];
    int J[3][2];
    int T[3][2];
} Pieces;

extern int PieceArrayList[7][3][2];

pieces.cpp:

#include "pieces.h"

int PieceArrayList[7][3][2] = {
    {{0, -1}, {0, 1}, {0, 2}},
    {{-1, -1}, {0, -1}, {-1, 0}},
    {{1, 0}, {0, 1}, {-1, 1}},
    {{-1, 0}, {0, -1}, {1, 1}},
    {{0, -1}, {0, 1}, {1, 1}},
    {{0, -1}, {0, 1}, {-1, -1}},
    {{-1, 0}, {1, 0}, {0, -1}},
};

TetrisPieces Pieces {
    **PieceArrayList[0], 
    **PieceArrayList[1],
    **PieceArrayList[2],
    **PieceArrayList[3],
    **PieceArrayList[4],
    **PieceArrayList[5],
    **PieceArrayList[6],
};

this allows me to access pieces via index, meaning i can iterate though them, while also i can access data via struct variables / fields, like this Pieces.I

#

whatever, this works for me, i consider my question solved. if anyone have comments about this feel free to do so
