WHAT ADVANTAGES DO 64-BIT PROCESSORS HAVE OVER 32-BIT? Apr 05 2013. Author: Andrey Karpov. There are 3 most obvious advantages of 64-bit processors over their 32-bit counterparts: extended address space, capacity increase, and larger number of general-purpose registers. The extended 64-bit address space theoretically allows the processor to work with 16 Ebytes (2^64) of physical memory within the SO, YOU WANT TO SUPPRESS THIS WARNING IN VISUAL C++...

Myth 1. Rust's arithmetic is no safer than C++'s. Myth 2. The only strong point of Rust is object lifetime analysis. Myth 3. Rust's function calls touch memory without goodreason.
COPY-PASTE PROGRAMMING The copy-paste programming method is a widely spread coding anti-pattern (a trap). This method is usually understood as multiple copying (with further editing) of existing code instead of creating general solutions. This programming style often produces excessively large, poorly readable functions that contain a lot of repeating codefragments.

WHY IT IS IMPORTANT TO CHECK WHAT THE MALLOC FUNCTION RETURNED By the way, there is another excuse for developers, why they don't check what the malloc function returned. malloc function only reserves memory, but does not guarantee that there will be enough of physical memory, when we begin to use the allocated memory buffer. Therefore, if there are still no guarantees, it is not necessary to perform acheck.
DIFFERENCE BETWEEN %P AND %X Functions belonging to the printf function family have the type specifiers "%p" and "%x". "x" and "X" serve to output a hexadecimal number. "x" stands for lower case HOW MUCH MEMORY CAN AN APPLICATION ACCESS IN WIN32 AND WIN64? The maximum size of program stack is 1 Gbyte for both 32-bit and 64-bit applications. (The stack size is defined by the linker and is 1 Mbyte by default) For a 32-bit application launched in a 32-bit Windows, the total size of all the mentioned data types must not exceed 2 Gbytes. (Actually it is 1.75 Gbytes due to memoryrequirements of the
HOW TO CHECK IF A 64-BIT PROJECT IS BEING BUILT IN VISUAL You may easily do it using #define preliminarily defined in the compiler. The following is the code that shows in what mode a project is being built – 32-bit mode or 64-bit mode (AMD64 or Intel 64) orin Itanium mode.
CRITICIZING THE RUST LANGUAGE, AND WHY C/C++ WILL NEVER DIE Suppose an entire program is written in unsafe C/C++ and its execution time is, say, 0.9*1 (a small portion of hot code) + 0.1*1 (a bulk of cold code) = 1. Now compare it to a program written in a safe language with C inserts: 0.9*1 + 0.1*2 = 1.1, which, theoretically speaking, makes the difference of 10%.PVS-STUDIO DOWNLOAD

PVS-STUDIO IS A SOLUTION TO ENHANCE CODE QUALITY, SECURITY Sadly, static analyzers are not perfect, which is why time from time you can get false positives. They are easy to suppress. For example, in the Visual Studio PVS-Studio plugin, you need to click one button - “Mark As False Alarms” (see our video on how to suppress false positives).

PVS-STUDIO FOR VISUAL STUDIO Many of our articles are focused on anything, but not the PVS-Studio tool itself. Whereas we do a lot to make its usage convenient for developers. Nevertheless, our efforts are often concealed behind the scenes. I decided to remedy this situation and tell you PVS-STUDIO'S NEW WEBSITE: HOW WE DESIGNED IT The PVS-Studio website turns 15 this year. This is quite significant for any internet resource. Back then, when our website was born, Russia announced 2006 as a year of humanities.

This article is for those who are tired of this, and who decided it is t WHY DO 64-BIT APPLICATIONS WORK FASTER THAN 32-BIT ONES? The difference in performance between 32-bit and 64-bit versions of applications depends greatly upon their types, and the data types they are processing. But in general you may expect a 2-20% performance gain from mere recompilation of a program - this is ex WHY IT IS IMPORTANT TO CHECK WHAT THE MALLOC FUNCTION RETURNED We'd like to present the series of articles dealing with the recommendations on writing code of high quality using the examples of errors found in the Chromium project.

Frequent questions and honest answers How to integrate PVS-Studio into an existing project and not drown infalse positives?
Use the mass suppression mechanism. PVS-Studio saves data about currently uninteresting errors to a special file. The analyzer will only issue warnings for new or recently changed code. As for the technical debt, you can tackle it later by fixing errors and tuning the analyzer step by step. More.
What about false positives? Sadly, static analyzers are not perfect, which is why time from time you can get false positives. They are easy to suppress. For example, in the Visual Studio PVS-Studio plugin, you need to click one button - “Mark As False Alarms” (see our video on how to suppress false positives). You can also report the problem to our support. If fixthe false alarm ,
you’ll see a decrease in false alarms after a PVS-Studio update. Which platforms does PVS-Studio support? PVS-Studio supports 64-bit Windows OS, Linux OS, and macOS systems. It can analyze code written for 32-bit, 64-bit and embedded ARMplatforms.
Where do I integrate the PVS-Studio analyzer? You can integrate the PVS-Studio analyzer into popular build systems, IDEs, modern built-in systems, CIs and cloud CIs. Click hereto see the entire
