C # variables, data type conversions, escape characters

Variable:

in the In C # , the types of variables are:int,double,string,Char , andbool are some of these types.

In C # , a variable's declaration can be a public global variable, or it can be a local variable inside a method.

For example: You can declare a local variable inside the entry method:

public static void Main (string[] args)

{

int i_01;

Double i_02;

String name1;

Char char1;

BOOL bool_01;

declare the variables, and be sure to initialize them.

i_01=2016;

i_02=3.1415926;

Name= " singing the motherland!" ";

Char1= ' a ';

Bool_01=true;

}

Data type conversions:

Implicitly-Typed conversions:

System.Console.WriteLine (" age =" +18);

convert integers to string types automatically

Explicit type conversions ( coercion type conversions ):

System.Console.WriteLine ((int.) 3.1415926);

force conversion to an integer by a parenthesis

Escape character:

\‘

\"

\\

\b

\ t

\v

\ n

\ r
