Functions and Modular Programming

Flashcards covering key concepts from the lecture on functions and modular programming.

Modular Programming

Breaking a program up into smaller, manageable functions or modules.

Function

A collection of statements to perform a task.

Function Call

A statement that causes a function to execute.

Function Definition

Statements that make up a function, including its return type, name, parameter list, and body.

Return Type

The data type of the value that a function returns.

Void Function

A function that does not return a value.

Parameters

Variables containing values passed to a function.

Arguments

Values passed into a function at the time of the call.

Local Variables

Variables defined inside a function that are not accessible outside of it.

Global Variables

Variables defined outside of all functions, accessible to all functions defined after their declaration.

Static Local Variables

Variables that retain their contents between function calls.

Default Arguments

Arguments that are passed automatically to a parameter if the argument is missing on the function call.

Function Prototypes

Declarations that notify the compiler about a function before a call.

Passing by Value

When an argument is passed to a function, its value is copied into the parameter.

Passing by Reference

Using a reference variable to allow a function to modify values stored in the calling environment.

Function Overloading

Having multiple functions with the same name but different parameter lists.

The exit() Function

Terminates the execution of a program and can indicate the status of program termination.

Stubs

Dummy functions used in place of actual functions for testing.

Drivers

Functions that test other functions by calling them with various arguments.
