B と C に共通だった部分は、 別クラスにして一応解決致しますた。 レス下さった方々どうもありがとう。
このほうがわかりやすくないか？ int ***malloc3D(int x, int y, int z) { int ***p = malloc(sizeof(int**) * x); int i, j; for (i = 0; i < x; ++i) { p[i] = malloc(sizeof(int*) * y); for (j = 0; j < y; ++j) p[i][j] = malloc(sizeof(int) * z); } return p; }

より、詳細で描画いたしますと(・_・) //A.h #include "B.h" class A { B b;}; //B.h #include "B.h" class B { A a }; このよーなばわいでございます！インクルードガードがついているものと考えて下さい！ (^^; よろしくお願い致しますm(_ _)m
