    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...

    Help me to fix this code in C language. This code converts infix expressions to postfix and then evaluate the expression. Right now, it works with single digits. I need to modify it so that it can evaluate expressions with also 2 digits, example: (60+82)%72. Additionally I need to display an error when the parenthesis don't match like (89+8(. I have muted some line that would print the postfix expression with a space like: 22 8 + when the input...

    In c++ Section 1. Stack ADT – Overview  Data Items The data items in a stack are of generic DataType. This means use should use templating and your Node class. Structure  The stack data items are linearly ordered from the most recently added (the top) to the least recently added (the bottom). This is a LIFO scheme. Data items are inserted onto (pushed) and removed from (popped) the top of the stack.  Operations  Constructor. Creates an empty stack.  Copy constructor....

    EVALUATING GENERAL INFIX EXPRESSIONS INTRODUCTION The notation in which we usually write arithmetic expressions is called infix notation; in it, operators are written between their operands: X + Y. Such expressions can be ambiguous; do we add or multiply first in the expression 5 + 3 * 2? Parentheses and rules of precedence and association clarify such ambiguities: multiplication and division take precedence over addition and subtraction, and operators associate from left to right. This project implements and exercises a stack-based algorithm that evaluates...

    Total point: 15 Introduction: For this assignment you have to write a c program that will take an infix expression as input and display the postfix expression of the input. After converting the postfix expression, the program should evaluate the expression from the postfix and display the result. What should you submit? Write all the code in a single file and upload the .c file. Problem We as humans write math expression in infix notation, e.g. 5 + 2 (the...

    By using PYTHON language Postfix to Infix using Stack Develop a stack application that can convert Postfix notation to Infix notation using the following algorithm. In your stack application, you can use only two stacks, one for a stack that can store Postfix notation, and the other is a stack to store infix notation. Also, it would help if you had a function to distinguish between an operation or an operand. Input A B C * + D E /...

  • write a C program that evaluate algebraic expressions over real numbers in Reverse Polish Notation (RPN)

    Your program must evaluate algebraic expressions over real numbers in Reverse Polish Notation (RPN). + (addition), - (subtraction), * (multiplication) and / (division) should be treated as arithmetic operations. Depending on the selection, numerical values must be entered and displayed in decimal, hexadecimal or binary form. Example: The expression ((3+4) *(7+1.6-12) -5) / (3-8.7)Will be calculated on your RPN calculator as 3 4 + 7 1.6 + 12 - * 5 - 3 8.7 - / Your RPN computer's user...
