Unary operators
An expression in which all operands in the experession are floating point numbers
Floating point (decimal) expressions
An expression that has operands of diffrent data types
Mixed expressions
When a value of one data type is automatically changed to another data type
Implicit type coercion
A memory location whose content is not allowed to change during program execution
Named constant
A string containing no characters
Null
Also known as type conversion or type casting - is used to explicitly convert one data type to another data type
Cast operator
A memory location whose content may change during program execution
Variable
=; assigns whatever is on the right side to the variable on the left side
Assignment opperator
