Algorithms: Are well-defined procedures for solving problems.
Data Structure: Is a particular way of storing and organizing data in a computer so that it can be used efficiently.
Dangling Pointers: Pointers that point to invalid addresses. Some examples of programming errors that can lead to dangling pointers include casting arbitrary integers to pointers, adjusting pointers beyond the bounds of arrays, and deallocating storage that one or more pointers still reference.
