# 🧮 **Mega Matrix Mania** — Advanced Terminal Matrix Calculator in C
A robust matrix manipulation program written in **pure C**, designed to perform essential and advanced linear algebra operations including determinant, inverse, rank, row echelon form, scalar multiplication, and more — right from your terminal interface with **safety-first input mechanisms** and **vibrant ANSI-styled output**.
> 🛠️ This project was developed as a part of **B.Tech (Engineering)** coursework at **Shah & Anchor Kutchhi Engineering College**, Mumbai by **Anvay Mayekar** for subject **Problem Solving and Programming with C** **(FE - Sem II)**, with a focus on modular design, efficient matrix handling, and real-world C programming principles.
---
## 📌 Highlights & Safety Notes
> ⚠️ All input is thoroughly validated via dedicated functions (`get_choice`, `get_scalar`) that prevent segmentation faults, malformed input like `3..3`, alphabets, or overflow issues.
> 🧠 All floating-point values are **truncated with a warning**, not rounded.
> 🔂 **Row Echelon Form** logic is **purely iterative** — no recursion used, ensuring memory safety and performance.
> 🖥️ Terminal outputs are color-coded for better readability.
> 💡 **Tip:** For operations on larger matrices, increase the value of `MAX` in [`utils.h`](./utils.h).

## 🔐 Input Safety Features
✔️ **get\_choice()**
→ Accepts 1 or 2 inputs like `3` or `3 3`
→ Rejects alphabets, symbols, and malformed input (`3..2`)
→ Provides truncation warnings for decimals (e.g., `2.7` → `2`)
→ Validates value range (`1–10`) or custom via `del` variable
✔️ **get\_scalar()**
→ Accepts any real number input (e.g., `-2.5`, `0`, `123`)
→ Rejects invalid or non-numeric entries safely
✔️ **input\_matrix()**
→ Only triggered after valid dimension entry
→ Ensures each matrix element is a valid number (float)
✔️ **Row Echelon**
→ Uses pure **iteration**, not recursion, for efficiency and safety
