Predefined functions: available in C / C++ standard library such as stdio.h, math.h, string.h etc. Outline Review of concepts in previous lectures Introduction to pointers Pointers as function arguments Pointers and … Pointers In earlier chapters, variables have been explained as locations in the computer's memory which can be accessed by their identifier (their name).

Some definition: A function is a named, independent section of C code that performs a specific task and optionally returns a value to the calling program or/and receives values(s) from the calling program.
Basically there are two categories of function: 1. Pointers as Function Arguments When pointers are passed to a function : The address of the data item is passed and thus the function can freely access the contents of that address from within the function In this way, function arguments permit data-items to be altered in the calling routine and the function. This way, the program does not need to care about the physical address of the data in memory; it simply uses the identifier whenever it needs to refer to the variable.
