When we call a function with parameters taken by value, it copies the values to be made. This is a relatively inexpensive operation for fundamental types such as int, float, etc. If the parameter is composed of a large compound type, this may result in a certain overhead. For example, let’s consider this following function to combine name, mid name, and surname.
string fullname (string…
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…

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”…
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…
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 function includes statements and other functions.
In general use, they are defined together as below,
myfunction() // this…
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…
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 application statements, and functions. We can create C++ files without the main function and we can use them as a library…
