Work with 2D arrays or nested vectors for matrices.

Prefer std::string for safe, flexible text handling.

Handle null-terminated char arrays carefully.

Create, concatenate, and compare std::string objects.

Run the body at least once with do-while.

Exit loops with break; skip iterations with continue.

Organize logic into functions with clear parameters and return types.

Pass by value, const reference, or pointer/reference for mutation.

Return by value (NRVO/moves help) or out-parameters when needed.

Define multiple functions with the same name and different parameter lists.
