Accessing array cells not by "number"?

Question

Hello.
How can I access cells in an array not by "number", but by the type I want? Well, for example, I wanted char[]
int array[];
array["hello"] = 1;
Thank you all in advance.

Answer 1

c++ map container

Answer 2

No. A raw array is essentially just a region of memory. Array indexes (numbers) are shifts in this memory relative to the beginning of the array.
Associative containers, such as hash tables, have similar behavior. One implementation in C++: en.cppreference.com/w/cpp/container/unordered_map

Answer 3

std::map

Answer 4

No way
