Hungarian notation is an identifier naming convention in computer programming, in which the name of a variable or function indicates its intention or kind, and in some dialects its type.
lAccountNum : variable is a long integer ("l")
rwPosition : variable represents a row ("rw");
Child:
The nodes connected directly below a parent are called child nodes. In a tree, every child has exactly one parent. That’s what makes a tree a tree.
The tree is a data structure of profound importance. It’s used to tackle many recurring challenges in software development, such as:
• Representing hierarchical relationships.
• Managing sorted data.
• Facilitating fast lookup operations.
