C # Tutorial, Methods

 Hello, Welcome to C# Tutorial. My name is Abdul Yesdani. Today we are going to learn about methods in C# programing language. Method is a bunch of code or statements which perform a single task. Here you can see the method example.     static void Hello(string name)         {             Console.WriteLine("Hello!" + name +"  Welcome to C#");             Console.WriteLine("Methods can have n number of statements");             Console.WriteLine("method will perform a single task");         } Methods can have parameters as shown in the above example, 'string name' is a parameter must be passed its value at the calling method in side the Main() method.

C# Tutorial, Arrays

Hi, Welcome to all. My name is Abdul Yesdani. Today we are going to learn about arrays in C#. In our previous postings we have worked with variables. One variable can store only one value. If we want to store multiple values of same type, array variable is there to do that job. What is an array? An array variables is capable of storing multiple values of same type.   Syntax:  datatype[ ] arrayName = new datatype[size]; Example: int [ ] myNumbers = new int [ 5];  The above array variable  myNumbers is capable of storing 5 integer values. In the memory it will allocate 5 slots to store 5 values, index starting from 0 to 4. Array indexing will always start with 0 and end with size -1. Types of Arrays in C# : There are 3 types of array in C#.  Single dimensional array, multi dimensional array and jagged array. Single dimension array represent a single column or row of values. The above example is for the same. Multi dimension array represent 2 dimension or 3 di...

C# Tutorial, Decision making & loop statements

 Hello, Welcome to C# learning. My name is Abdul Yesdani. Today we are going to discuss about decision making or branching statements and looping or iteration statements in the C# language. Decision making statements: To make a firm decision we will use decision making statements. For this we will use specific key words such as if, if-else. example: A buyer   wants to buy a product, but he will make a decision to buy it if  the product is available for less than some x amount. int price = 180; if (price < 200)   Console.WriteLine("Buy the product"); if() statement checks Boolean value of a variable , means the value is true or false. price is assigned with 180. In the statement if (price < 200) , the boolean value is true. When the value is true the statement or block of statements which follows if will get executed. So out put will be Buy the product. int price = 280; if (price < 200)       Console.WriteLine("Buy the product"); else ...
