C# pronounced as See Sharp. A more powerful object oriented programming language than C++. The # symbol has 4 + (plus) in it to show its superiority to C++.
Applications written in C# make use of the .Net Framework. The .NET Framework consists of Common Language Runtime (CLR) and Frame work class library (FCL).
Variables – To store some data, we make use of variables. It will allocate some memory to store this data.It is possible to change the information that a variable holds during runtime. A variable name can start with an alphabet or an ‘_’. Try to make the name meaningful or descriptive. This is a good coding practice.
Variable Data types – We need to declare the type of data that our variable will store and how much memory need to be allocated to it.
Eg: We need to store the age of a person. We use the data type int.
; is used for terminating each line of code. Now we need to assign a value to our variable age. It can be done in 2 ways.
int age; age = 32;
or int age = 32;
The only thing to remember is that you need to declare the data type of a variable before you assign value to that variable. Other data types are float, bool, char, string, double – all of these are built-in data types.
There’s a data type called var for which you let the compiler decide the variables’ data type. var a = 2; means the compiler will assign the data type of integer to the variable a.
Constants – A variable whose value you do not want to change during the execution of a code is associated with the keyword const. eg: Const int year = 2017;
Download and install Visual Studio Community Edition to start coding. Choose default configuration. It would take a while to install 🙂
