char info[15][15]; // 2 dimensional array is used since u need to store multiple strings in a single place.
Single dimension (char) array store a bunch of characters in contiguous memory locations & create a string.
Now since we need to store a bunch of strings (1-dimensinal array) in contiguous memory locations , we need another dimension to the array.
Also since you are already using c++ , I would suggest to use std::strings as its more high-level than raw strings & more work-able in code
