7
Which statement describes the punctuation conventions used for character data?
Char literals are enclosed in single quotes when assigned to a variable.
Char literals must be enclosed in single quotes when assigned to a variable
Character literals are not surrounded by asterisks; they use single quotes.
Char literals are enclosed in double quotes when assigned to a variable.
8

Why are primitive data types useful to programmers?
They give more control by letting prog define data manipulation and storage
They save time by specifying what to do with data, not how to do it.
They are the simplest variables and need no functions for data manipulation
They aren't built-in but can be created using composite data types.

Floating-point numbers can be expressed in decimal notation or E notation
Floating-point numbers can be positive or negative.
Floating-point number have a decimal point with at least one digit after it
22
The = operator ____ , while the == operator ____.
Assigns a value to a variable; checks if two operands are equal.
Compares two operands for equality; can assign and compare in one step.
