You're developing a realtime application, and don't know how to add values to elements of an array?????

Pull my other leg: it'll play a tune for you.

What is the criterion by which you would...

To give you a clue about what's happening, 100! is about 9.3 by 10^157. To represent that, a 525 bit integer is needed (and that increases 530 bits to represent 101!). 64 bit is nowhere near...

You need to be careful with executable compression. Compressed executables have some characteristics associated with self-modifying code (the decompression stub unpacks code and data into memory). ...

It doesn't matter where you do it, as long as you obey the one-definition rule (ODR). Typical projects link together object multiple object files to create an executable, and each object file is...

The only way in which a constructor can report an error is by throwing an exception.

The C++ standard has this to say (in Section 15.2 "Constructors and destructors" which is within Section 15...

That statement is inaccurate on so many levels that I'm speechless. Non-virtual functions can also be overridden, but the behaviour differs from overridden virtual functions due to "name hiding", as...

Dogma (n) : A firmly held belief based on faith, and often stated as fact.

If there are common things that all classes which handle triangles have to do, put those functions into their own class (eg TriangleModelFile derived from ModelFile). Derive the specific/multiple...

The array declaration int a[n]; is not valid C++. Your compiler doesn't complain because it supports this as an extension. (Your compiler might also support the 1999 C standard (where such things...

Start with T(0) = 1.

In a loop use the fact that T(n+1) = x*T(n)/(n+1) to compute each term. Add the terms together.

Oh, please! Huge integer libraries or strings are needed for some things, but falling back on them for basic problems like this is crazy.

The program can go to much higher terms simply using the...

The above is common practice, but it is easily broken. Imagine, for example, a class that supports its own operator&() - it will not perform as you intend.

Generally, it is better to code in a...

Not even close.

You have declared myclass's length() method as taking one argument, and yourlen() calls it with two arguments.

Similarly, yourlen() is declared with no arguments, but when you...

You're asking the wrong question. The compiler will attempt to invoke a copy constructor (assuming one exists) upon any attempt to create a copy of an object.

The real practical concern is...
