Stack in C++
A stack in C++ is a data structure that follows the Last In, First Out (LIFO) principle. This means that the last element added to the stack will be the first one to be removed. Think of it like a stack of plates: you add new plates to the top of the stack, and when…
Linked List in C++
A linked list in C++ is a linear data structure storing elements in separate objects called nodes. Each node contains two parts: data and a pointer(reference) to the next node in the sequence. This structure allows for the Linked List’s dynamic memory allocation, insertion, and deletion operations. Linked List Program in C++ Here’s an example…
