Learn how to define functions, the different parts of a function, and the rules that govern the naming of functions.
📖 Read more about Function Definitions
A function prototype provides the compiler with the necessary information about a function before its actual definition, ensuring correct function calls and parameter checks.
📖 Read more about Function Prototypes
Delve into how functions receive input in the form of parameters and how they communicate back results using return statements.
📖 Read more about Function Parameters and Return Statements
Learn how to assign default values to function parameters, enabling more flexible function calls.
📖 Read more about Default Argument Values
Discover the power of function overloading, where multiple functions can have the same name but different parameters, offering versatility in handling different data types and structures.
📖 Read more about Overloading Functions
Explore how to efficiently pass arrays, vectors, and structs to functions, enhancing the function's capability to process complex data structures.
📖 Read more about Passing Arrays 📖 Read more about Passing Vectors, Structs
Grasp the difference between passing by value and passing by reference, and understand when to use each method for optimal results.
📖 Read more about Pass By Reference
Understand the rules that govern the visibility and lifetime of variables within functions, ensuring the correct use and management of data throughout your program.
Delve into the nuances of invoking functions, the flow of control, and the intricacies of nested and recursive function calls.
📖 Read more about Function Calls
Discover the concept of inline functions, which aim to increase the execution speed of your program by embedding the function content directly into the calling code.
📖 Read more about Inline Functions
Journey into the world of recursive functions, where a function calls itself to solve problems that inherently have a recursive structure.
