What Is A Function and How To Create Function In PHP, Python, JavaScript, C/C++, C#, Bash, Java , PowerShell Programming Languages?

A function is a basic element of the programming languages. The function is derived from mathematics where complex operations are summed and aggregated together for multiple use cases. In programming, languages function provides abstractions, simplicity, elegance for code which can be used multiple times with a simple call. Syntax Of The Function The function is provided with different programming languages with different syntax but most of them are very similar...


Php – Class

[rps-include post=6522] Php programming language supports most of the Object Oriented Programming concepts. Object Oriented Programming provides a lot of useful features to manage big and enterprise applications. Object Oriented Programming Object Oriented Programming or OOP is a concept that provides different features to implement real world problems. Up to now we have used variables to write Php applications but as you know enterprise applications can not work with those...


Php – Functions

[rps-include post=6522] Up to now we have write simple and little codes but a real applications can not be accomplished with this type of code. We need to write a lot of code and use some part of the code again and again without same copies. Functions gives us the ability to use given part of code to run multiple time and from different parts of the applications. Functions also...


C – Structures

[rps-include post=6557] C provides primitive data types like int , char , float etc. But in order to solve real world problems we need more than these types. Newer object oriented languages have a lot of features to implement real world situations. For example C++ provides Object Oriented features where we can implement real world objects. C lacks of these features but provides struct type. Struct is used to provide composite data type which can provides...


C Functions – Create and Run with Examples

[rps-include post=6557] Functions are a grouping statements to perform operations. Why we group statements in a function? While developing applications same operations can be done thousand of times and writing same code a lot of time is not efficient and exiting. Also changing single statement will require all of the copied statements to change. Every C applications have at least one function which is the entrance function named main() . Below we...


Linux Bash Define, Call Functions

[rps-include post=6835] Generally bash commands are executed regularly. So running complex or multiple commands one by one are difficult. Or sometimes we just want to accomplish task with just one command without diving into it and distribute this command. Here are functions to make things very easy. Functions get parameters and execute functions code. Function has two way to create. Here are syntax for. Prefer second one because portability is...


Javascript Define and Call Functions

Up to now we have write out code line by line. But there is problem with that. What will we do if the same 3 line code should be used in different 120 places. Here functions come to play. Functions a block of code that can be used just with single line.

function  is the keyword used to specify function sum is the name of the function and will be...


Python Pass Statement

Python provides different keywords which do not exists in other programming languages.  pass is one of the original keyword used for  nothing. pass keyword is a requirement for python block specification and syntax. Why To pass? Other languages generally uses some block specifier like {} or ;  etc. For example we can define functions but if we do not provide the body this may create some conflicts. So we need some statement...


Python Class Tutorial with Examples

Class is a popular paradigm used in programming language.  Object oriented programming is created the class structures in order to work programming structures like a real world objects. Class and object words are used to express similar things. Object Class defines the data types, functions, behaviours but do not holds any data or mostly can not used in a practical manner in python. We should create objects from classes. We...


Python Modules Tutorial With Examples

While learning python programming language we generally write some code or sample applications. But these will generally consist of few line of code below 100 lines. In real world applications situation is different. We generally write a lot of code, function, helpers etc. Generally these applications consist of above 10.000 lines of code. Putting all of these code into single or few py files is not a practical or logical solution....
