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:

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…
Another one of the most used logical operators in C++ is switch() statement. A switch statement allows you to check variable and you can branch to different cases in accordance with it’s value. Each cases can be defined for different values, and the variable being…
One of the important part in programming is logics in functions and main program. Each these conditions are important to decide how code flow will work in runtime. In programming we use conditions and if – else statements. In C++ if statements can be done in one line or multi lines and it supports the logical conditions as same as used in mathematics. Conditions are logical operators and…
While loops allow you to repeat a block of code as long as your specified condition is reached. Loops are used very offend in programming because they save time, reduce errors, and they make code more readable.
1. The While Loop
In the mechanism of the while statement…
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…
