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...
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...
Introduction Variables are seen as memory cells that can be accessed using their identifiers. This way we did not have to care about the physical location of our data within memory, we simply used its identifier whenever we wanted to refer to our variable. The memory of your computer can be...
We decided to write several small posts on how C/C++ programmers play with fire without knowing it. The first post will be devoted to an attempt to explicitly call a constructor. Programmers are lazy creatures. That's why they tend to solve a task using minimal code amount. This aim is...
C++ FAQ's I've spent the past few weeks learning C++, and here are a bunch of FAQ's I came up with. Some of these Q n A's are from various sources, but I have edited and revised them using my own words. What is C++? C++ is a computer programming language. Its name is literally...
Abstract Introduction 1. Potential errors 2. How it all begun 3. Phantoms 4. Diagnosis of potential errors Conclusion References
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...
In C, memory allocations on heap are done using following three library methods void *malloc(size_t size); void *calloc(size_t nmemb, size_t size); void *realloc(void *ptr, size_t size); Though, most commonly used is malloc() The corresponding free-ing the memory...
Abstract In this article, Anatoliy Kuznetsov answers the questions and tells us about the open BitMagic C++ Library. Introduction While regularly looking through the Internet-resources related to the sphere of 64-bit programming, I often came across mentioning about BitMagic C++ Library...
In C-Style typecasting we discussed about type casting and why is it required and how it is used in C programming. C++ has more types of typecasting and an entirely different way to use them. A point to be noted that C++ typecasting would be mostly described and used in context of classes, as...
Virtual functions in C++ play an important role. To understand virtual function, one should be clear about the polymorphism feature of C++ language as an object oriented language. In brevity, polymorphism is the weapon through which we can identify a function call through its parameters, or...
In the previous article I explained you about the Templates in C++. C++ comes with the Standard Template Library, or STL, which includes many different types of containers, each with its own set of advantages (and disadvantages). The C++ Standard Template Library is a very large library of...
Another method for printing the date from starting to ending This method is useful if u r dealing with dates.If u want to do some operation using the date and then fetch another date and do vice versa it is useful. #include<iostream> #include<malloc.h> using namespace std; int ...
In part I of the article about Virtual Functions, we learnt about the virtual functions, why are they needed and when to use them. This article will talk about virtual function internals and how virtual functions work in C++. Actually, virtual functions govern to an extent, how a class object is...
Abstract Introduction Building of the 64-bit version of Loki in Microsoft Visual Studio 2005 Testing of the 64-bit Loki version with the help of Viva64 Incorrectly used constant LONG_MIN Some types of magic numbers - errors or not? Addition of int to a pointer as a potential error Using...
We recently saw a tutorial on Vectors in C++. Now its time for better things. So we all know what a set is. It is a group of elements in which there is no duplicate. Consider we need a container with following features: -> add an element, but do not allow duplicates -> remove elements -> get...
Abstract Introduction Analysis of program code Examples of incorrect and vulnerable code Diagnosis of vulnerabilities in 64-bit code Conclusion References Abstract
There are three techniques used to pass variables into a C or C++ functions. Pass by value C/C++ Pass a pointer by value C/C++ Pass by reference C++ only Pass by value The function receives a copy of the variable. This local copy has scope, that is, exists only within the function....
This is a basic attempt to accomplish this, there is already a real big load of code about this matter... I wanted to use a different approach, I created 1 table that contains all the 256 bytes, and i used it to make the conversion.. you look at the code, better The tables ...
To the programmers it is very common concept that bugs are of two types i.e logical errors and syntactic errors. Poor understanding of the problem and solution procedure leads to logical errors whereas, the syntactic errors arise due to poor understanding of the language itself. We can detect these...
