ASSIGNMENT IN A VARIABLE:

To assign a string in a variable, the string must be enclosed in double quotes.
To access a particular member of a variable '.' operator is used.
- If variable name is X and we want to access its member Y, then we write as X.Y
To assign a variable with any value, assignment operator ( = ) is used.
Variable name and the member of the variable is written on the left hand side and the value which is to be assigned to that member is written on the right hand side.
Syntax:
- Variable_name.Member_name = " string_value"
