In a exam, ill have to use the in built Linked Lists/Stacks/Queues. Surely I cannot write the whole code.
How do I use that and its functions?
How do I implement an already built in Stack/Queue/LinkedList
It actually depends on your class incharge/instructor and what approach she/he wants you to take. For user defined classes, you can write only functions that you are going to use as a way to save time. Or you can use inbuilt methods too.
For competitive programming competitions, inbuilt classes is the way to go.
There exist header files that have these data structures already implemented in them.
For example, you can use
#include<vector> header file in C++ to use vectors and all their functions.
#include<map> to use maps
#include<stacks>, #include<queue>, etc
Checkout STL for c++`
