In the functions that we created in previous posts, their parameters have always been passedby value. This means that, when we call a function, what is passed to the function are the values of these parameters on that moment of the call. Variables are copied into the variables represented by the function parameters. Let’s remember an example,
#include <iostream>
int add (int…
In the C++ programming language, we can add functions with many parameters, each parameter may have different types. We can add as many parameters as we want by defining its type and its name to be used inside that function separated with ‘,’ coma. We can shape…
In C and C++ programming language there are two parts of a function, Declaration, and Definition.
Function Declarationis the combination of the return type of function, function’s name, and parameters in parenthesis.Function Definitionis the body of the…
We explained how to declare and define simple functions. They had no return, and in a previous post we explained that main function has an integer return that represents our code is successfully done or not. In C++ programming language, we can easily define many functions and some functions may have return values some may not. We can return single variables like integer numbers (int), floating…
Functions, also known asProceduresorSub-Programs,Sub-Algorithms,allow to structure programs in segments of code to perform tasks. A Function is a group of statements that has function a name and can be called with parameters to operate…
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…
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. In this video, you will be looking into the latest features and updates to the specification and see how they affect code…
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…
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 applications, we have a lot of variables and every variable stored in the RAM and it takes space in the memory, These variables…
