How to convert word to letter array c++?

Question

C++ / C#

There is a word that is already an array element, you need to convert this word into a new array of letters, it would be good if it turned out like this word[i][k], where i is the number of the array element, which means the number of the word in the string, and k is the number of the letter in word

Answer 1

So the string itself is already an array, isn't it?
