**Typecasting** a variable means converting a variable from one data type to another. There are two types of typecasting in Pascal:
* **Implicit typecasting**: Typecasting in which the range of values of the source data type is *less than* the range of values of the destination data type is called implicit typecasting.
* **Explicit typecasting**: Typecasting in which the range of values of the source data type is *greater than* the range of values of the destination data type is called explicit typecasting. 

# Variable typecasting
**Variable typecasting** temporarily converts the data type of a variable. It does not change the contents of the variable. The variable typecasting of a variable can be done as follows:

```Pascal
_newDatatype_(_variable_)
```
* **`_newDatatype_`**: The datatype in which `_variable_` will be converted.
* **`_variable_`**: The variable to be converted into the datatype `_newDatatype_`.

> Note: Variable typecasting works on the variables whose addresses we can take.

# Variable typecasting vs value typecasting
We can use variable typecasting on *both sides* of the assignment operator. We cannot use value typecasting on the *left side* of an assignment. 

# Code
## Example 1
Consider the code snippet below, which demonstrates the use of *variable typecasting*.


program Example1;
var 
  ch1: Char = 'a';
  num1: Integer = 10;
begin
  writeln('');
  num1 := Integer(ch1);
  writeln('a typecased as integer: ', num1);

  ch1 := Char(num1);
  writeln('97 typecased as character: ', ch1);

end.

pascal

## Explanation
* *Line 7*: A character `ch1` is typecased to an integer `num1`.
* *Line 10*: An integer `num1` is typecased to a character `ch1`.

## Example 2
Consider the code snippet below, which demonstrates variable typecasting on the left side of an assignment.

program Example2;
var 
  ch1: Char = 'a';
  ch2: Byte;
begin
  writeln('');
  Char(ch2) := ch1;
  writeln('byte typecased as char: ',ch2);

  Byte(ch1) := ch2;
  writeln('char typecased as byte: ',ch1);

end.

## Explanation
* *Line 7*: A byte `ch2` is typecased to a character `ch1`.
* *Line 10*: A character `ch1` is typecased to a byte `ch2`.

What is variable typecasting in Pascal?

Typecasting a variable means converting a variable from one data type to another. There are two types of typecasting in Pascal:  Implicit typecasting: Typecasting in which the range of values of the source data type is less than the range of values of the destination data type is called implicit typecasting. Explicit typecasting: Typecasting in which the range of values of the source data type is greater than the range of values of the destination data type is called explicit typecasting.
