Learning to Program in C++

C

C Function

A C function is one that is inherited from the C library. Because C does not have a number of features that have been added in C++, such as function overloading and reference arguments, C functions must often be called in different ways from those we use when calling a C++ function.

C Library

The C library is a collection of functions that were originally written for users of the C programming language. Because C++ is a descendant of C, these functions are often still useful in C++ programs.

C String

A C string is a literal value representing a variable number of characters. An example is "This is a test.". C strings are surrounded by double quotes ("). Please note that this is not the same as the C++ string class.
