Ruby Comments

Ruby comments are non executable lines in a program. These lines are ignored by the interpreter hence they don’t execute while execution of a program. They are written by a programmer to explain their code so that others who look at the code will understand it in a better way.

Types of Ruby comments:

• Single line comment
• multi line comment
