A Template is a simple and a very powerful statement in C++. A Template Function may have multiple template parameter types, and the function can still use regular non-templated types. In a previous post, about Function Overloading, we had two add() functions working with integer and float numbers, in that example we can say add() function is overloaded with int and float parameter types, and…
Learn C++ With Making Games Start Fast: A Story About Concurrency by Mathieu Ruport (CPPCon 2020) Video
April 26, 2021
Games taking too long to get started is a common criticism in game development. Players dislike it and developers spend a long time watching screen loading. The audience will be shown how Intel vTune can be used to profile threading problems, how “thread safe”…
Learn C++ With Back to Basics: Smart Pointers by Rainer Grimm (CPPCon 2020) Video
April 25, 2021
An important feature in C++11, from the library’s perspective, are smart pointers. Smart pointers are more than smart designed pointers. Smart pointer models are semantic. Understanding the semantic ownership of smart pointers is the key focus of this video and your…
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…
