A switch statement is used to check a variable value against list of other values. The values are called cases, and can be of any datatype. Switch Statement are useful in programming when you want to make a decision based on a variable value. It’s easier than using ‘If’ statement for larger set of values... » read more
The ‘if’ Statement is one of the most used decision-making statement in programming. Whenever you need to test a condition; the ‘if’ statement can be used. The ‘if’ statement checks if a statement true or false and route the program based on the result of that statement. ‘if’ statement Flowchart Syntax of ‘if statement’ ... » read more
C#, just like other languages, contains reserved words. These words are called keywords. Keywords have meaning to the compiler and cannot be used as variable, class, or any other object in the program. Keywords in C# are categories as the following: Modifier keywords: Modifier keywords are keywords that can modify type and type members. They... » read more
Operates are symbols that tell the compiler to perform a mathematical or logical operation. There are used to manipulate a variable or constant. And easy form of operator is the “+” operator, which tells to add a value to a variable. Operators example int x = 3; x = x + 1; Where x is... » read more
A namespace is a C# elements that is used to organized your program and separate the codes. Namespace can contain classes, variable, methods, properties, etc. the main usage of namespace is to avoid conflict between classes that have a similar name. It also provides way to put related object under one name space. Example: the... » read more
A variable is a name given to a memory space that the program will use and manipulate. The variable should have a data type, depending on what we want to store in it, and the size of data that can hold. Define a Variables In C#, we define a variable as the following: <DataType> VariableName; ... » read more
Data types are everywhere in programming. They are used to define the type of variable declared in a program. In C#, there are three types of data types: The value types. The reference type (Object, dynamic, and string type) Pointer data type. We will discuss how to define, assign, and manipulate variables in the next chapter.... » read more
It’s has became a tradition to start the first programming language lesson with the famous “Hello World!” program. The program simply prints the string “Hello world” in the output window. To get started, open visual studio, select new, C# Program. using System; namespace myfirstCSharpProgram { class HelloWorld { static void Main(string[] args) { Console.WriteLine("Hello world!");... » read more
As mentioned earlier, C# programming is very much similar to C, C++ and Java. Having basic of these languages would help you to get along with C# without much difficulty. It also helps to have basic knowledge of Object Oriented fundamentals. Software requirement IDE (Integrated Development Environment), you can install the Microsoft visual studio community... » read more
