Structures and Functions (Part 1)

Understanding Structures in Programming Structures are user-defined data types that group elements of different types into a single type. For example, struct student combines name, age, roll number, and marks into one entity. This allows for efficient organization and manipulation of related data within programs.

Passing Structure Members as Function Arguments Structure members can be passed to functions like regular variables or by their addresses using pointers. By passing structure member values directly or through references (addresses), programmers can manipulate specific parts of the structure efficiently without duplicating entire structures.

Creating Custom Character Sets with Structures Custom character sets can be created using structures containing character and integer members to represent letters and associated codes respectively. Using pointer-based function arguments enables dynamic input from users while maintaining memory efficiency during operations such as printing key-value pairs on screen.
