T/F Expressions that are tested by the if statement are called Boolean expressions.

True

Escape operators: \n \t \' \" \\

\n (causes output to be advanced to new line) \t (causes output to skip over to tab over) \' (causes single quote to print) \" (causes double quote to print) \\ (causes backslash to print)

interpeter

A _______________ is close in nature to machine language

low-level language

Although a CPU only understands _______________ language, it's impractical for people to write programs in machine language. _______________ was created as an alternative to machine language. Instead of binary instructions, assembly language uses mnemonics. Assembly language programs cannot be expected by the CPU, so an _______________ is used to translate an assembly language to a machine language program.
