This document discusses different ways that functions can access arguments in C programming including pass by value which copies the argument's value and pass by reference which copies the argument's address, allowing changes to the parameter to affect the argument. It also mentions static and global memory, local variables stored on the stack, dynamic memory allocation, and recursion in functions.

Functions
Prototype
Pass by value
Pass by reference
This method copies the address of an argument into the
formal parameter. Inside the function, the address is used
to access the actual argument used in the call. This means
that changes made to the parameter affect the argument.
This method copies the actual value of an
argument into the formal parameter of the
function. In this case, changes made to the
parameter inside the function have no effect
on the argument.
