Data Types & Type Conversions in C#

• int a=23; //Allocated 4 bytes
• float c= 3.45; //Allocated 4 bytes
• decimal d=0.555555555; // Allocated 16 bytes
• bool h= true;
• char c =’A’;
• string greetings =”Hi all”;
• double = 4.33333365; // Allocated 8 bytes
• short = 2; // Allocated 2 bytes

Type Conversion:

Data type can be converted into similar types. And this conversion is called casting. It is of two types. They are:

1. Implicit casting:
   
   Data types can be converted implicitly as well as explicitly. Implicitly, the conversion is done by the compiler but there is threat of losing data. It is also called implicit casting. In implicit casting, no external cast function is written.
   
   Example:
   
   Int x;
   Double y= x;
   
   Here, x is integer in start but it is changed into double without writing any casting function.
   
   
2. Explicit casting:
   
   Explicitly, the conversion is done by using casting to avoid threat of losing data. In explicit casting, external predefined function is written. They need a cast operator.
   
   Example:
   
   double y = 123;
   int x = (int)y;
   
   Here, y is double in start but it is explicitly changed into integer by writing cast function.
   

There are different type Conversion methods. They are,

Example:

After execution the output generated will be:
