Exit Not that, when step 5 is executed, There should only be one number on STACK. Example: ABC+*DE/- a=5, B=6,c=2,D=12,E=4 Postfix expression Program #include <stdio.h> #include <conio.h> #include <string.h> char postfix[20]; int stack[20]; int top = -1; void get_po...
logics of the evaluation. In the Mathematica's form, that is no longer so. For another example, suppose Deriv is a function that takes a function f and returns a function g (the derivative of f), and we want to apply g to a variable x. In lisp, we would write “...
