•There are two kinds of programming language:
–Some languages such as Lisp and Prolog
– have
an interpreter that performs a statement as soon as you type it in. With these languages you get instant feedback on whether the statement you just wrote makes any sense or not.
–Other languages such as Fortran and C++ are called compiled languages. They separate the process of writing the program, compiling it into machine code, and running the program into three separate steps.
