Inline functions advantages
What is the inline function and what is the use of inline function?
Paul_Singh
- Feb 7th, 2012
The inline keyword is a request to the compiler that you want the function body to be inserted into the compiled code as opposed to a function call. Typically used for functions that are called very o...

Inline function: they are same as Normal function but compiler treat them diffrently. When we call a inline function compiler will replace the call by inline function body (It depends upon how you hav...

Constructor initialization lists
What is advantage of using Constructor initialization lists?
Paul_Singh
- Feb 7th, 2012
For some object the initialized list is necessary because they are const or do not have default constructors. However, the main advantage is that if you construct the object in the constructor body th...

What are the different way of creating object in c++ ?
NikunjSingh
- Feb 23rd, 2012
1. using normal object creation: Shape obj; 2. copy ctor: Shape obj2=obj;// or Shape obj3(obj); 3. using new operator;
Code- #include <iostream>

1. Create on stack. i.e. ClassA varA;
2. Create on heap. i.e. ClassA *ptrA = new ClassA;Dead Code

Hi Dead code (a.k.a Unreachable code),as the name suggests is the portion of the code which is never executed. Point out the word NEVER , as the code above that made the break before that and the exec...

Dead code is such a collection of lines of code or code which executes but it its result does not have any significance or affect on output.
Can destructor be private?
NikunjSingh
- Feb 23rd, 2012
Destrcutors can be made private to stop user from creating objects on stack. One can still create objects on stack using a static function as member function. But if intention is not to let user crea...

YESSSS destructors can be private. Infact this concept is used in Singleton design pattern. So, outsiders cannot delete object of that class. It has to b deleted from the class itself. I know...I...

Command routing is passing commands to its targeted objects.When a command is routed, it goes to the main frame. From the main frame, it is routed to the child frame of the active view; it is then rou...
What do you mean by inline function?
The idea behind inline functions is to insert the code of a called function at the point where the function is called. If done carefully, this can improve the application's performance in exchange for increased compile time and possibly (but not always) an increase in the size of the generated binary executables.

An Inline function is a function that is expanded in line when it is invoked. That is compiler replaces the function call with the corresponding function code.. :)

An inline function is a function where a copy of the logic is embedded in the application at each the point where it is called by the compiler. This basically allows a reduced overhead in function dereferencing

Why we follow top down approach in C-language and bottom up approach in C++?Explain in detail.

The question is wrong. In most cases, regardless of the language, top down is the better approach. Actually TDD forces this. You must first know what you want, that is, how the client code will use it, before you can design it. Always top down. Just remember that.

When designing solution in an object orientated language you start by defining the lowest key players, or entities, and then begin describing how they interact. This is bottom up. In C which is a func...

Using the class name. In case of non static function we need to use the this pointer.
