The size of a class can be changed simply by playing with the order of its members' declaration: struct A { bool a; int b; bool c; }; /*sizeof (A) == 12*/ On my machine, sizeof (A) equals 12. This result might seem surprising because the total size of A's members is only 6...
C++ is by Bjarne Stroustrup in 1979. It was created as an enhancement to the C language. It is a combination of higher and low level programming language. It is a superset of the C language. It is case sensitive and provides support to generic and procedural programming concepts. Object oriented...
Many of us might have wondered at sometime or the other about how to pass a variable number of arguments to C++ functions : something like a printf function. I don't know how many are aware of this, so I decided to post an article on this topic. Background When a function is declared, the...
Making a Phone Book application in C++ is interesting; because it lets you learn the language practically. Making sample applications in any programming language is an interesting job. And this is perhaps the best approach to learning any programming language. As a programmer, your goal is to...
Polymorphism is in short the ability to call different functions by just using one type of function call. It is a lot useful since it can group classes and their functions together. It is the most important part of Object-Oriented Programming. Polymorphism is the core of object-oriented programming...
Introduction This article talks about Function Object and it's uses over Function Pointers Background A Function Object, is an Object of a class that defines an operator () and can be called as a function. When a function object is used as a function, the function call operator() is...
Printing the date from starting date to ending date The program takes the starting date and ending date as inputs and prints the dates in between them.This program is useful if u r dealing with dates. The code I have used four date functions i.e date1() , date2() , date3() , date4(). When...
Introduction - What is priority Queue A priority queue is an abstract data type (ADT) supporting the following three operations: 1. Add an element to the queue with an associated priority 2. Remove the element from the queue that has the highest priority, and return it 3. (optionally)...
Problems of testing 64-bit applications. Andrey Karpov Evgeniy Ryzhkov http://www.Viva64.com March 2007 Abstract. The article observes some questions related to testing the 64-bit software. Some difficulties which a developer of resource-intensive 64-bit applications may face and the...
If two process are there and one shared memory is there. One wants to write the data and another wants to read the data to the shared memory. I have written a program in which if process1 is writing to shared memory another will wait and vise varsa. To undersand these programs one should have...
Good has won this time. To be more exact, source codes of the Chromium project have won. Chromium is one of the best projects we have checked with PVS-Studio. Chromium is an open-source web-browser developed by Google and intended to provide users with fast and safe Internet access. Chromium...
In this article we are going to explain some of the most fundamental but often neglected concepts of C++ programming language. These concepts are extremely interesting and if employed well, can solve complex mathematical problems. So, without wasting any more time, let us jump to the first concept...
Programmers, meet a new tool to search for errors in source code of software written in C/C++. Within the scope of the PVS-Studio analyzer, we implemented a new set of general-purpose rules. This functionality is free for now. You may download PVS-Studio here...
This is just for a kind of information. Here I am going to explain how to make a class so that user can create object of it on free List( heap memory) or Stack. Example 1: Object should be created Only On Heap memory.Idea is that make constructor as private so that no one create on stack....
Introduction Many times you may have wondered how to return several values from a C++ function. I know it's easy for most of you when you know "how many" values your func is going to return. I have seen many people use std::pair to return two values from a func. But what about the case when you...
I thought of adding this small code snippets to thelibrary which just reverses the content of the array. Not sort in ascending/descending order, but put last array entry to first, etc. EG.. if array consists of {2,3,4,7,12,98},, need to output {98, 12,7,4,3,2} #include <iostream.h> #define...
We know that C++11 added the feature of rvalue reference. Here assumption is that the reader is already familiar with rvalue and lvalue and their references. As we know that we declare rvalue reference with double ampersand like: int&& var1 = 10; // var1 is an rvalue reference variable means it...

Background Normally most of software Engineer uses singleton design pattern in daily coding life. It's very simple , vast uses but still i saw in many softwares which is not handled proper in C++ based products/projects. One thing more you can'nt design singleton as perfectly behaved singleton....
From the Bubble sort it was obvious that the sorting isn't efficient for larger list, even for a list more than 100 numbers . So there's another lot of sorting algorithms out there and this is just one of them Selection Sort Once you see the way Selection sort works, you'll wonder why one...
