What is a mathematical function library? |
Probably a math class, which is why C++ would be needed. Too bad he didn't listen to me. |

| A math class or library is just a snippet or chunk of code you can use for functions or solving problems. Like game patches except you choose when to use them. |

What? You actually don't know what a math class is??
Is this like, a language thing? |

A class is an "object" (from which the term OOP is derived), or a specially labeled peice of code that defines specific functions and variables that're applicable when the class is in use. A math class would be an object that defines mathematical functions for a program, such as the value of PI, or anything, really.
You could conceivably have more than one math class for a single program. Let's say, for example, you're an astrophysicist for NASA, and you're trying to figure out propulsion for a Mars rover. You'd want one math class that defines various physical conditions as they are on earth (like g=9.8 m/sec^2, or the effect of Earth's magnetic field, or wind resistance) and another that defines physical conditions as they are on Mars. (which lacks a magnetic field, and where gravity is significantly lower, and the atmosphere thinner) Same for the value of Pi, which, as the distortion caused by gravity increases, approaches 1.
That way, he could have one fuel efficiency equation that would produce different results depending on the value of variable "g" and dozens of others. A class just allows you to "toss" all that into one or two or twenty chunks instead of trying to define everything individually, which, when you're working with hundreds, or thousands of linked variables, is a big help. Classes can do more than define values and fuctions, btw, I'm just using that as an example, and probably goofed doing that because of my n00bish computer skillz. 
The kicker here is that C++ is C, but specifically designed for object oriented programming, which Wardrich has been trying to tell Tinman47 for months. And now Tinman is asking how to create classes in C, which is the exact reason people use C++ instead of C. 
(BTW, check your private messages!) |

But by now we all probably know that TinMan47 likes to reinvent the wheel or recasting old ideas. The 'proven good' concepts aren't swell enough for him. |

Thanks Dogbreath. The explanation I was waiting for was something like: A library is a file, in a format acceptable by a linker, containing entry points and code that implements specific tasks.
My next question would then be: What is a program.

No, it is a way of teaching. By asking the student to explain the question in detail, the student will often discover for him/herself what the solution is.
It is a time-consuming method and therefore not used often, but in a forum like this I think it is the perfect way to teach. Instead of putting all the burden on the teacher, it forces the student to work it out himself (with a little guidance). A reasonable way of sharing the burden I think, since I am doing this on a volountering basis. If tinman47 paid for my time, I would/could have provided him with a straight yes/no answer, but he would not have learned anything substantial. |

Hey, that was really deep what you said MiniMax,but I know a substanstial amount of code you know. Just because I have been a programmer for only 1 year doesn't mean I don't know alot. |

Or, when the student already knows the answer, just wastes his time and makes you look a little stupid and more than a little bit strange? There're ways to teach by asking questions while still making it obvious that you're trying to teach, that way people who aren't your "pupils" aren't trying to answer your questions, Socrates.
