Use 2D arrays for matrices and tables.

Represent strings as null-terminated char arrays.

Use string.h helpers: strlen, strcpy/strncpy, strcmp, strcat carefully.

Store addresses with pointers and dereference safely.

Declare typed pointers and initialize them before use.

Advance pointers by element size with ++ and + offsets.

Provide the function body that implements the declaration.

Pass arguments by value; use pointers to modify caller data.

Return results with return; use void when returning nothing.

Write functions that call themselves with a base case.
