The following program (written in C++) creates a filter program for converting ascii into ROT13 encoding. A very simple cypher where each character in the alphabet is replaced with the 13th letter from its position.

Ok… this is a “Hello World” program in C++ using objects. It illustrates a number of aspects of object oriented programming in C++ allowing you to get a quickstart into C++ programming. First there is the #include directives which tells C++ that the program uses two libraries, iostream and string (actually they specify the header … Read More “Hello World C++ with Objects” »
