Advanced calculator with graph plotting, and financial tools using QT

SmartCalc v2.0

Welcome to the SmartCalc v2.0 repository, an advanced C++ calculator implementing object-oriented programming principles.

Overview

SmartCalc v2.0 is an OOP modification of the SmartCalc v1.0 , now including the ability to calculate complex arithmetic expressions, utilize the variable x, and graph functions. This version also introduces credit and deposit calculators as additional features.

Features

• Expression Calculation: Supports basic arithmetic, mathematical functions, and variable usage.
• Graph Plotting: Ability to graph functions using the variable x.
• Credit Calculator: Special mode for calculating various credit-related metrics.
• Deposit Calculator: Functionality to calculate deposit profitability.

Technical Specifications

• Language: C++ (C++17 Standard)
• GUI: QT
• Directory: Source code in src folder
• Coding Style: Google C++ Style Guide
• Namespace: s21
• Testing: Comprehensive testing with GTest
• Build System: Makefile with standard GNU-program targets

MVC Pattern

The Model-View-Controller (MVC) pattern is central to the application's design, ensuring a clear separation between business logic (model), user interface (view), and interaction logic (controller).

Functionalities

• Dijkstra's Algorithm: For converting expressions to reverse Polish notation.
• Arithmetic Operations: Includes basic operations and mathematical functions like sine, cosine, logarithm, etc.
• Variable x Usage: For expressions and graph plotting.
• Graph Plotting: With coordinate axes, scale marks, and an adaptive grid. Domain and codomain are within -1000000 to 1000000.
• Expression Length: Supports up to 255 characters.
• Precision: Accuracy up to 7 decimal places.
• Arithmetic and Mathematical Functions: Comprehensive support for various operations and functions in different notations.

Bonus Features

• Credit Calculator: For calculating monthly payment, total overpayment, and total payment based on various inputs.
• Deposit Calculator: To compute accrued interest, tax amount, and total deposit value at the end of the term.
