Advanced Calculator

Advanced Calculator is a comprehensive C++ application developed during my graduation, offering 40+ mathematical operations across 5 domains. Designed for students and professionals, it combines academic rigor with practical utility through object-oriented design and precision-focused algorithms. Feature Breakdown
1. Arithmetical Operations

• Basic: Addition, Subtraction, Multiplication, Division

• Advanced:

  • Statistical: Average, Mean, Correlation

  • Number Theory: Prime checks, Even-Odd detection

  • Combinatorics: Permutations (nPrnPr​), Combinations (nCrnCr​)

  • Algebraic:

    • Quadratic equation solver

    • Factorials (n!n!), Square roots (xx​), Powers (xnxn), Roots (xnnx​)

2. Geometrical Computations

• 2D Shapes: Square, Rectangle, Circle, Triangle, Rhombus, Parallelogram, Trapezium

• 3D Solids: Cube, Cuboid, Sphere, Hemisphere, Cone, Solid/Hollow Cylinder

3. Financial Tools

• Simple & Compound Interest

• Profit/Loss Analysis

4. Trigonometric Functions

• Angle calculations via diagonals:

  • sin⁡θ

  • cos⁡θ

  • tan⁡θ

5. Technical Architecture

• C++ implementation with modular class design

• Error handling for division-by-zero/invalid inputs

• Double-precision floating-point accuracy

This tool bridges theoretical math with practical computation, reflecting both academic foundations and professional-grade engineering principles from my software development career1
