Stacks are used by compilers to help in the process of
evaluating expressions and generating machine language code.In this
exercise, we investigate how compilers evaluate arithmetic
expressions consisting only of constants, operators and
parentheses. Humans generally write expressions like 3 + 4and 7 /
9in which the operator (+ or / here) is written between its
operands—this is called infix notation. Computers “prefer” postfix
notation in which the operator is written to the right of its two
operands. The preceding...

JAVA, please You must write a robust program meaning that your program should not crash with any given data. Data validation must be done any time that user enters an input. Write a program that 1. Gets an infix expression form the user and evaluate the expression using stack ADT a. Finds the postfix equivalent of the given infix expression b. Evaluate the created postfix expression. c. Note: your program should not crash when you enter an invalid expression such...

implement a class of infix calculators (Using C++). Consider a simple infix expression that consist of single digit operands; the operators +, -, *, and / ; and parentheses. Assume that unary operators are illegal and that the expression contains no embedded spaces. Design and implement a class of infix calculators. Use the algorithms given in the chapter 6 to evaluate infix expressions as entered into the calculator. You must first convert the infix expression to postfix form and then...

We as humans write math expression in infix notation, e.g. 5 + 2 (the operators are written in-between the operands). In a computer’s language, however, it is preferred to have the operators on the right side of the operands, i.e. 5 2 +. For more complex expressions that include parenthesis and multiple operators, a compiler has to convert the expression into postfix first and then evaluate the resulting postfix. Write a program that takes an “infix” expression as input, uses...

In C programming Language Write a version of the infix-to-postfix conversion algorithm. Write a program that converts an ordinary infix arithmetic expression (assume a valid expression is entered) with single-digit integers For Example: Infix expression (6 + 2) * 5 - 8 / 4 to a postfix expression is 62+5*84/- The program should read the expression into character array infix and use the stack functions implemented in this chapter to help create the postfix expression in character array postfix. The...

Write a java program for the following: Your program reads an infix expression represented by a string S from the standard input (the keyboard). Then your program converts the infix expression into a postfix expression P using the algorithm. Next, your program evaluates the postfix expression P to produce a single result R. At last, your program displays the original infix expression S, the corresponding postfix expression P and the final result R on the standard output ( the screen...
