Introduction

If you are interested in coding, then you must have heard about the stack data structure. It's one of the essential data structures that are used in programming, and it is prevalent in C++. Stack is a data structure that works based on Last In First Out (LIFO) principle. That means, the elements that are added last to the stack will be taken out first. There are many functions of the stack data structure, and one of them is to perform arithmetic operations. That's where a Stack Calculator comes in handy, and in this article, we'll be discussing Stack Calculator C++.

The Concept of Stack

A stack data structure is an ordered list of elements where all insertions and deletions take place at one end, which is called the top of the stack. The top of the stack represents the position where the last item was inserted. The bottom of the stack represents the area where the first item was inserted. Whatever element is at the top of the stack, it will get popped out first. The operations that affect the stack are push, pop, peak, and empty stack.

The Purpose of a Stack Calculator C++

A stack calculator is designed to performs arithmetic operations using stack data structures. The idea is based on the reverse polish notation approach, where the numerical values are first entered into the stack, followed by the operators of the arithmetic expression. A stack calculator C++ will have multiple stacks like value stack, operator stack, and extra stack which maintains the order of execution. It utilizes the LIFO principle of the stack to evaluate the arithmetic expressions.

Stack Calculator C++ Code:

The following code shows how to implement a stack calculator in C++. Here we used STL stack to implement the stack data structure. Take a look at the code:

```C++#includeusing namespace std;stack st;int parse(string s){ int ans=0; for(int i=0;;i++) { if(isdigit(s[i])) ans=ans*10+s[i]-48; else break; } return ans;}int main(){ string s; getline(cin,s); stringstream ss(s); while(ss>>s) { if(isdigit(s[0])) st.push(parse(s)); else { int cur = st.top(); st.pop(); int pre = st.top(); st.pop(); if(s==+) st.push(pre+cur); else if(s==-) st.push(pre-cur); else if(s==*) st.push(pre*cur); else if(s==/) st.push(pre/cur); } } cout<Explanation of the Code

The input is taken by string parsing through the getline() function. It allows the user to input a line of arithmetic expressions like 4 5 + 2 *, which means first add the 4 and 5, then multiply the result by 2. We can define multiple stacks using the STL stack function. The parse function extracts all the numerical values from the input string and returns it as an integer value. The postfix notation is implemented using the operators from the string line that are evaluated using conditional statements.

Advantages of Stack Calculator C++

The Stack Calculator C++ has several benefits, some are:

Easy to implement.
Good for solving complex mathematical problems.
Efficient when dealing with large input sizes.
Fast, accurate calculation of expressions using the LIFO principle.
No need to worry about operator precedence or parentheses.

Disadvantages of Stack Calculator C++

The disadvantages of Stack Calculator C++ are:

It requires a thorough understanding of the stack data structure.
It can be complicated to handle complex functions or expressions.
Debugging can be challenging if there's a problem in the code.
It takes time to learn, especially for beginners.

Conclusion

Stack Calculator C++ is a great tool for solving mathematical problems efficiently. It only requires basic knowledge of C++ programming language and stack data structures. The idea behind the reverse polish notation approach is brilliant, and it simplifies the execution of arithmetic expressions. However, it has its disadvantages, and every programmer should be aware of them. Despite that, stack calculators are essential in many areas of computer science, including software development, algorithms, and artificial intelligence.

Comparison Between Stack Calculator in C++

Its most significant advantage is its ability to perform calculations on a stack data structure, making it easy for users to keep track of their operations. There are various stack calculators in the market, and this article aims to provide a comparison between some of the best ones.

Features of Stack Calculators

Stack calculators have several features that make them unique from other types of calculators. Here we will discuss some of the essential aspects of stack calculators:

Reverse Polish Notation

One of the most common features of stack calculators is the use of Reverse Polish Notation (RPN) to carry out calculations. RPN is a mathematical notation where operators come after the operands; for example, instead of writing 2 + 3, you would write 2 3 +. RPN is easy for the calculator to process, and it also solves the ambiguity that might arise with traditional infix notation, where the order of operations needs to be considered.

Stack Data Structure

Another crucial feature of stack calculators is the use of a stack data structure. A stack is a data structure that operates on a Last-In-First-Out (LIFO) basis, where the last item added to the stack is the first one to be removed. The stack allows the calculator to keep track of previous calculations and display them to the user as needed.

How to create a Stack Calculator in C++

Introduction

C++ is widely regarded as one of the best programming languages available today. One reason for this is its versatility. You can use it to create small, basic programs, or you can do more complex things like creating tools, games, and applications. In this article, we’re going to explore how to create a Stack Calculator in C++, which is a fundamental program that every beginner should learn.

What is a Stack Calculator?

A stack calculator is a simple, yet incredibly useful program that allows you to evaluate mathematical expressions using a stack data structure. It’s an excellent program for learning how to use stacks and manipulating them. The program has a display where you enter the numbers and operators, and then the stack handles the calculations, displaying the result.

The Stack Data Structure

The first thing we need to understand when creating our Stack Calculator is the stack data structure. A stack is a basic data structure that follows the Last-In-First-Out (LIFO) principle. That is, whatever goes into the stack last will be the first to come out.

Creating the Stack Class

We will begin by implementing the Stack class. As mentioned earlier, a stack follows the LIFO principle, which is why we’ll use a linked list approach to implement the stack.The Stack class will have the following methods:

- Constructor (to initialize the stack)
- Destructor (to free up memory after the end of the program)
- Push (to insert an element into the stack)
- Pop (to remove an element from the stack)
- IsEmpty (to check if the stack is empty)
- Peek (to return the top element of the stack without removing it)

The Stack Implementation

Here’s how we can implement the Stack class:

```class Stack{private: struct Node { double data; Node* next; }; Node* top;public: Stack() { top = nullptr; } ~Stack() { while (!IsEmpty()) Pop(); } void Push(double x) { Node* newNode = new Node; newNode->data = x; newNode->next = top; top = newNode; } void Pop() { if (IsEmpty()) cout << Error: Stack is empty! << endl; else { Node* temp = top; top = top->next; delete temp; } } bool IsEmpty() { return (top == nullptr); } double Peek() { return top->data; }};```

We created a Node struct that holds the data and points to the next element in the stack. The `top` pointer keeps track of the head of the list. We then implemented each method by manipulating the pointers.

The main function

The next step is to put all this together in the main function. Here’s what the `main` function for our program should look like:

```int main(){ Stack S; string expression; getline(cin, expression); stringstream str(expression); string element; double operand1, operand2, result; while (getline(str, element)) { if (element == +) { operand2 = S.Peek(); S.Pop(); operand1 = S.Peek(); S.Pop(); result = operand1 + operand2; S.Push(result); } else if (element == -) { operand2 = S.Peek(); S.Pop(); operand1 = S.Peek(); S.Pop(); result = operand1 - operand2; S.Push(result); } else if (element == *) { operand2 = S.Peek(); S.Pop(); operand1 = S.Peek(); S.Pop(); result = operand1 * operand2; S.Push(result); } else if (element == /) { operand2 = S.Peek(); S.Pop(); operand1 = S.Peek(); S.Pop(); result = operand1 / operand2; S.Push(result); } else { double operand = stod(element); S.Push(operand); } } cout << Result: << S.Peek() << endl; return 0;}```

The program's main function works as follows:

1. We create a Stack object `S`.2. The user enters a mathematical expression that the program will evaluate.3. The program reads each element of the expression and checks if it is a number or an operator.4. If it’s a number, we convert it to a double and push it onto the stack.5. If it’s an operator, we pop two numbers from the stack and perform the operation on them. The result is then pushed back onto the stack.6. Finally, we display the result.

Conclusion

In this tutorial, you learned how to create a stack calculator in C++. You implemented the Stack class and the main function to handle the input and calculation of mathematical expressions using a stack data structure. Keep practicing this and other basic programs, and you’ll soon find yourself becoming comfortable with C++.
