Lisp is especially used for work in Artificial Intelligence. For example, CS 261, Artificial Intelligence , uses programming in LISP in its study of expert systems. The shell comes back and generates another prompt once Scheme has stopped. In Scheme, processing proceeds by typing expressions into the Scheme environment. After each expression is entered, Scheme reads the expression, evaluates the expression to determine its value, and prints the resulting value.
Numbers are expressions, whose value or meaning is the number itself.
Type several numbers into Chez Scheme , typing one number at a time. In each case, note how Chez Scheme responds. Enter a read number with many digits. Determine what happens when you enter a fraction. In Scheme, we apply operations to data using a prefix notation with parentheses.
