私はこれが本当であることを知っていた：
x[4] == 4[x]
多次元配列に相当するものは何ですか？次のことは本当ですか？
x[4][3] == 3[x[4]] == 3[4[x]]
ベストアンサー
x[y] is defined as *(x + (y))
x[y][z] would become *(*(x + (y)) +
z)
x[y[z]] would become *(x + (*(y +
(z))))
x[4][3] would become *(*(x + (4)) + 3)
would become *(*(x + 4) + 3)
3[x[4]] would become *(3 + (*(x + would become
(4))))*(*(x + 4) + 3)
3[4[x]] would become *(3 + (*(4 + would become
(x))))*(*(x + 4) + 3)
つまり、それらはすべて同等です。
