C++: variable name and function name not known till run time, virtual instance, observable difference
virtual instance, observable difference, object behaviour: The short answer is no. The longer answer is yes, but not directly. You have to provide the code to read the variable/function names and values and provide the code to map the name to the variable or function. This is because the names of functions and...
C++: variables, arithmetic operations, program execution
arithmetic operations, program execution, integer type: In programming languages like C++ variables are things that can hold a variety of values, and the value they hold may be modified during their life time - that is the value a variable hold may vary!

C++: virtual constructor and destructor, virtual destructors, virtual constructor
virtual destructors, virtual constructor, virtual destructor: Hello John, thank you for the question. 1. No, you cannot have a virtual constructor. Declaring a constructor virtual will result in a compile error. 2. Virtual destructors are commonly used with inheritance. Since an abstract class must contain a...
C++: virtual constructor, virtual constructor
virtual constructor: Hello, As far as common practice, when you inherit from a base class, make both the destructors virtual. This is allows for runtime binding with the compiler. Its like a way of making it smart and able to distinguish from when its calling a base or derived...
C++: virtual descructor, virtual destructor, widget types
virtual destructor, widget types, gui elements: The quick answer is that instances of derived types can be improperly destroyed if they are deleted through pointers to their base class. If such instances hold onto resources such as memory or file handles then these might not be released back to the system...
C++: virtual functions, virtual inheritance, virtual functions
virtual inheritance, virtual functions, virtual function: I think you may be confusing virtual functions with virtual inheritance.

C++: void POINTER, pointer arithmetic, void pointer
pointer arithmetic, void pointer, object pointer: In C and C++ a void pointer, or void * type, is a pointer type that points to no particular type of object. As such you cannot de-reference a void pointer (i.e. use what it points at) because the compiler has no idea to what type of thing it is pointing to....
C++: volatile modifiers, documentation states, modifiers
documentation states, modifiers, application code: What is the volatile modifier? --------------------------------- The volatile modifier is like the const modifier. The term used in the C++ standard is qualifier rather than modifier. Const and volatile are qualifications that can be applied to types. In...

C++: Sorry... =), int seed, space base
int seed, space base, void space: Well, if you could use a loop it would make things easier. But as it is the best way would be to add another recursive function to print spaces before calling col. You can then use the base_size - size trick to calculate how many spaces to print: #include...

C: C, array index, equivalence
array index, equivalence, pointer: Because in C, an array is an address or pointer to the first element. The first element is 0 bytes from the beginning, so an index of 0 for an array is the first element. This comes from the basic equivalence in C: a[i] = *(a+i) and when i is 0 a[0]...
C: C language, random number generation, drand48
random number generation, drand48, c language: Some compilers see the function definition: int drand48() as not providing type information for the parameter and therefore doesn t serve as a prototype.
