Overview

This project implements a calculator application with support for basic arithmetic operations, matrix math, and probability distributions.

Main Components

text.h/.cpp

Contains Text class with methods to print menus and execute math operations.

• matrix_menu() - Prints menu for matrix operations
• matrix_sum() - Adds two matrices
• matrix_diff() - Subtracts two matrices
• matrix_prod() - Multiplies two matrices
• matrix_transpose() - Transposes a matrix
• matrix_scale() - Multiplies a matrix by a scalar
• matrix_det() - Calculates determinant of a matrix
• basic_menu() - Prints menu for basic arithmetic
• bye() - Prints goodbye message

matrix.h/.cpp

Contains Matrix class to represent matrices and perform operations.

• inputMatrix() - Inputs matrix values from user
• printMatrix() - Prints matrix contents
• transpose() - Returns transpose of matrix
• scaleMatrix() - Returns matrix multiplied by scalar
• determinant_2_2() - 2x2 determinant
• determinant_3_3() - 3x3 determinant
• determinant_4_4() - 4x4 determinant
• fill() - Fills matrix from vector
• inverse_2_2() - Finds inverse of 2x2 matrix
• operator+ - Overloaded + for matrix addition
• operator- - Overloaded - for matrix subtraction
• operator| - Overloaded | for matrix multiplication
• operator[] - Overloaded [] for element access

crammer.h/.cpp

Implements Cramer's rule for solving a system of linear equations.

• get_ratio() - Parses equation string into coefficient ratios
• is_correct() - Checks format of equation
• start_crammer() - Implements Cramer's rule

probSolver.h/.cpp

Computes probability mass functions for various discrete distributions.

• factorial() - Computes factorial
• bernoulli() - Bernoulli distribution PMF
• poisson() - Poisson distribution PMF
• laplace_local() - Localized Laplace distribution PMF

main.cpp

Entry point and main application loop.

• Sets up signal handler for keyboard interrupt
• Prints operation menus and reads user input
• Calls appropriate functions based on input
• Loops until the user quits

The code demonstrates good practices like separating interface and implementation (text vs matrix), overloading operators, and using const correctness. Overall, it provides a useful set of math utilities in an easy-to-use application.
