C Programming Functions Quiz

Study Notes

Functions in C Programming

Functions are reusable blocks of code that perform specific tasks, improving modularity and organization.
They can return values to the calling code and can take parameters for input.

Calling a Function

Calling a function involves executing the block of code defined by the function name followed by parentheses containing any required arguments.
The control of the program transfers to the function, executes its content, and then returns control to the calling point.

Independent Functions

An independent function can operate without relying on data from other functions or global variables.
Independence promotes code stability and reusability, as functions can be tested and reused in different contexts without side effects.

Scope of Function Variables

Variables declared within a function are local and exist only during the function's execution, known as local scope.
Once the function terminates, local variables are destroyed, thus preventing them from being accessed outside that function.

Purpose of Recursive Functions

Recursive functions call themselves to solve problems by breaking them down into smaller, more manageable pieces.
They are used for tasks such as navigating tree structures or performing calculations like factorials, provided there is a base case to terminate the recursion.
