-

this question has answer here:

i trying write small 2d graphics library using sdl. want implement equivalent of matrix stack in opengl , implement functions pushmatrix() , popmatrix() in opengl. can coding matrix multiplications. need algorithm storing stack , managing transformations.

a stack array, or linked list, push operation creates copy of last/topmost element , appends @ end, , pop operation removes last element list/array.

using/implementing arrays/linked lists basic computer science knowledge.
