Astrodynamic / Line-calculator-with-graph-output-in-CPP-Qt

Engineer, credit and debit calculator. GUI implementation, based on any GUI library with Qt API for C++17. It allows arithmetic calculations, graph plotting, and variable calculation.

Line calculator with graph output

General Information

Calculator v1.0 is a command-line based and GUI scientific calculator developed in C++17. It allows users to perform arithmetic calculations, plot graphs of functions, and calculate the values of variables. The program is built using the Model-View-Controller (MVC) pattern, and its classes are implemented within the SmartCalc namespace. The calculator can handle both integers and real numbers with a dot, and allows input of numbers in exponential notation.

Build

The program can be built using the Makefile provided. The following targets are available:

• all: builds the program and runs the install target.
• build: installs the program.
• rebuild: removes any existing installation of the program, builds it, and installs it.
• install: installs the program.
• unistall: removes the program from the system.
• clean: removes any existing installation of the program and cleans up any build artifacts.
• cppcheck: runs the cppcheck tool to check for errors in the code.
• clang-format: runs the clang-format tool to format the code.
• tests: builds and runs the unit tests for the program.

To build the program, run the following command:

make all

Usage

After building the program, run it using the following command:

./Calculator

This will launch the GUI-based calculator. The program will accept input of arithmetic expressions and plot graphs of functions.

Dependencies

The program depends on the following libraries:

• GTest
• Qt 6

Development

The code for this project is located in the sourse folder. Classes are implemented within the SmartCalc namespace. The project follows the Google style guide for C++ code.

Examples of Usage

• To perform arithmetic calculations, simply enter an arithmetic expression into the calculator and press =. The result will be displayed in the output area.
• To plot a graph of a function, enter an expression in infix notation with the variable x. Then click on the Plot Graph button. The graph will be displayed in the output area.
• To calculate the value of a variable, enter an expression in infix notation with the variable x, and then click on the Calculate button. The result will be displayed in the output area.
