No credit for late submission Your task for this assignment is to implement a stack data structure in C++. This may be accomplished by utilizing the C++ standard template library (STL) or by utilizing a user-defined class. 1. Implement a transaction-based stack data structure using C++. The program will be interactive. Data transactions will be entered at the command line and results will be displayed on the console. Each input transaction will contain an arithmetic expression in post-fix format. Assume that each operand and operation (+, -, *, /, %, ^) is a single character in each arithmetic expression without spacing. You may assume that each arithmetic expression is correctly formatted. However, your program should not attempt the following: a. Divide by zero with / or % ... Instead, your program should display an error message and then begin evaluating a new input transaction. b. Perform % with non-integer operands 2. .. Instead, your program should display an error message and…

4. What are the applications of stack and queue data structure

Write a complete CFG that recognizes the language: L = {aibj | i ≤ j}

Runtime stack stores the activation records of the subprograms to determine the referencing environments for local and non-local variables referenced inside the subprograms. Show the stack with all activation record instances, including static and dynamic chains, when execution reaches position 1 in the following skeletal program. Assume bigsub is at level 1. function bigsub() { function a() { function b() { -1 }// end of b function c() { b(); }// end of c ... c(); }// end of a ... a(); ... }// end of bigsub
