can be executed by separate commands.
1: An interpreter generally processes the source code
directly or first tokenizes it into a byte-code type form
to interpret that.
2: An interpreter checks the errors of a program statement
by statement. After checking one statement, it converts
that statement into machine code and then executes that
statement. The process continues until the last statement
of program occurs.
