QuickCalc

A terminal-based calculator program was made using flex, bison, and C++.

Features

Basic Arithmetic Operations: Addition, subtraction, multiplication, and division are supported.
Built-in Functions: The calculator includes a variety of built-in functions such as trigonometric functions (sin, cos, tan), logarithmic functions (log, log10), exponential functions (exp), square root (sqrt), and more.
Reusing the previous answer: The calculator keeps track of the previous answer and allows users to reference it in subsequent calculations using _. If you want to access the previous answer, use _ in the calculation. If you want to use the answer two calculations ago, just use __ (2 times _)
Error Handling: Comprehensive error handling for invalid input and mathematical errors.
