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.

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.
