Basic Literals

Question 1

Describe Literals

Literals are the values on which the program ultimately performs operations.

Question 2

Integer numbers.

Answer 2

This is the set of values that are part of the set of whole numbers.

Question 3

Characters

Answer 3

A single character can represent a digit, a letter or another symbol. To write a symbol, we wrap it in single quotes. Character literals can represent symbols of an alphabet, digits from ‘0’ to ‘9’, whitespaces (‘ ‘), or other characters or symbols (‘$’).

Question 4

Strings

Answer 4

Strings represent text information. To write a string we wrap characters in double quotes instead of single ones.
