Function overloading in C++ with example program: This simple CPP tutorial code is all about overloading of functions. If more than two functions have a same name with different parameters[Or Arguments] in a program means that is said to be the functions overloading or methods overloading. And especially this source code is used to find the Area values. Example program is also listed at the bottom of this page.
