Software Development : Get Constant in C++
What does " const " mean to you? Does it just mean a value can not be changed? If so, you may want to read on! Const is one of those things, which though not unique to C++ is given more meaning when you leverage C++ fully, const allows you to not only define a value as invariant, but also to instruct other programmers coming to your code how a value should be used, how when it is passed as a parameter it should be treated and ultimately how to protect data from needless alteration, de-synchronisation or simple corruption. Const is therefore your friend, and if you've come to C++ from C, Java, C#, Python or one of the other myriad of languages which don't treat const with as much relevance as C++ you may want to read more than I can say on the topic. Bjarne Stroustrop (the inventor of C++) and other authors on the topic (notably Scott Meyers & Herb Sutter) explain in much more detail than I ever could, but for brevity here are two examples of const from my own c...
