The Main Functionis the main part of an application coded in C++, it is the designated entry point to a program that is executed in an operating system (on Windows, iOS, Mac-OS, Android, Linux etc.). Every C++ application program has a main function which starts all application statements, and functions. We can create C++ files without the main function and we can use them as a library…
Learn C++ With Modern C++ Safety and Security At 20 by Matthew Butler (CPPCon 2020) Video
April 18, 2021
With the features and language improvements aim to be more comprehensive than even C++11, the C++20 standard is now complete. Engineers employed in safety critical systems, protection or even applications that are exploited by customers every day have special language needs.
Do you want to learn how to overload a function ? What is Function Overloading ? What does overloaded function means ? How we can use Function Overloading in C++ ? How we can use multiple parameter types in our functions ? Here we go,Function Overloading is used to operate…
Learn C++ With Back to Basics: Move Semantics by David Olsen (CPPCon 2020) Video
April 16, 2021
One of the many powerful improvements of C++11 is Move Semantics. It addresses a variety of programming problems that have been vexed by C++ developers for years. However, moving semantics can be easily misused, and the nuances are often difficult to get correct. This presentation will benefit both those who are still learning how to write a strong robust C++ code and those who already know all…
1. Memory Address of a Variable
TheRAM(Random Access Memory) is the memory of a computer that can be read and changed in any order, typically used to store working data and machine codes. In some operations, we useROM(Read Only Memory), In our…
Thegotostatement is used to jump to alabelthat provides an unconditional jump from the goto to a labeled statement in the same function. We can also do the same loops as the same in for() while() loops by using goto statement. Instead of goto we…
Our screens are 2D dimensional planes and consists of pixels in X and Y directions. How we display a 3D object in this 2D plane ? 3D objects in our 2D screens are projection of 3D coordinates by using mathematical calculations. In 3D operations, i.e. in 3D graphics, 3D robotics, 3D mechanics; we use matrix forms which are multi dimensional arrays in C++. Generally they are 3 dimensional arrays…
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…
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 some step before counting all range,
for( int a=0; a<=10; a++)
{
std::cout << a << ",";
…
