In a previous post, we learned that pointers are variables to point address which is also an integer value. That means we can do arithmetic operations on a pointer variable. But do not forget that we operate on the addresses in our RAMs, so we should be careful and we should know the range well. Simply, we can use ++, –, +, and – arithmetic operators on pointers:
In a 32bit application…
Learn C++ With Design Patterns For Handling/Reporting Errors In C++: Parallel Algorithms And Executors by Mark Hoemmen (CPPCon 2020) Videos
April 11, 2021
The normal C++ error handling technique, exceptions, does not work out of the box. There is a need to develop new patterns for error handling. The video will be demonstrating how design patterns already exist for parallel error handling and how these design patterns will be…
1. Using break in Loops
break statement is used to break code-block in case statements and it is also used to jump out of a loop. In an earlier post, we used break in switch() statements.
For example we can break for() loops, in this loop below we can break in…
Arrays are used to define a data block in the memory with number of data types, like integer numbers, floating point numbers, characters, structures, … etc. C & C++ programming language provides this data structure, called as array that stores a fixed-size of elements of the same type. Arrays are generally used to store a collection of data, and it is often more useful to store data as a…
Learn C++ With Back to Basics: Design Pattern by Mike Shah (CPPCon 2020) Video
April 8, 2021
Design Patterns are interchangeable design elements that can help to make the program more manageable, scalable, and extensible. In this video, you will be learning the basics of the trends of artistic, structural and behavioral design. This talk is targeted at beginners who…
Learn C++ With Quickly Testing Qt Desktop Application with Approval Tests by Clare Macrae (CPPCon 2020) Video
April 4, 2021
This video will discuss the problems and possible sources of error that are unique to the code, which the Qt cross-platform graphical user interface library uses, and then explain how to defend against them. The video will also briefly discuss some other resources that can…
C Programming language is one of the oldest programming language. A lot of operands in other programming languages got inspiration from this language. C and C++ have the same operators and most of them are the same in other programming languages. In programming variable at the left side of the equation symbol is a new variable, or variable that will have new value from the right side of the…
In programming, one of the most used statement is for() loops. It is used to count in range with given conditions. If you know exactly how many times you want to execute a block of code in your loop, then they are very useful than other loops. Occasionally, it is used to…
In C programming language ASCII codes are used as in char arrays to store texts in ASCII mode. You can use char arrays in both C and C++, they are faster in operations and they have less memory usage. In s modern way, strings are useful for storing texts and they are defined…
Learn C++ With A Relaxed Guide to memory_order_relaxed by Paul McKenney and Hans Boehm (CPPCon 2020) Video
March 30, 2021
Over the years, the out-of-thin-air (OOTA) and read-from-untaken-branch (RFUB) properties of the memory order relaxed specification have caused considerable consternation. While there are no known instances of full-blown OOTA activity and no known RFUB-induced production code failures, the theoretical possibility of these properties seriously complicates automated analysis of large C and C++ code…
