Calculator

A beginner calculator C application

---

I made this program to retrive my C skills, To remember the basics of C

Features

• Power calculation
• Basic math (+, -, *, /)
• Calculating the square root of numbers
• Rounding (upwards and downwards)
• Garbage code, not organized at all
• Use this if you hate your life

How to compile this program?

NOTE: There is already a compiled version in this repository, but if you want to compile it yourself for whatever reason, This is how)

First install gcc

Arch: sudo pacman -S gcc

Debian: sudo apt install build-essential If it doesn't work try sudo apt update first

Fedora: sudo dnf install gcc

Termux (untested): pkg install clang

Then download the C code from this repository, And run gcc -o calc1 calc1.c -lm After that run ./calc1

NOTE: For termux or if you want to use CLANG please run: clang calc1.c -o math1 -lm and then ./calc1 normally

To verify the installation of gcc

Run: gcc --version

For termux and CLANG run: clang --version

How to use this program?

You will first be greeted with some NOTES:

"Type the letter "p" when asked for the type of calculation for calculating the power of something The letter "s" is for square root, While the letter "r" is for rounding (either upwards or downwards)" * Sign is for multiplication / is for division

How to use (format): ./calc1 [OPERATION (+, -, /, r, p, s, *] [FIRST NUMBER] [SECOND NUMBER]

Usage examples

1. Let's say you're studying, You came across a math problem. So you open your terminal and just type ./calc1 and you can easily calculate the problem

2. You are at the store, You aren't sure if you're correct about the calculation, But you have compiled the program on Termux (a sand-boxed linux-ish enviroment on your phone) So now you can use the program on your phone (un-tested, if there is any problems open a bug in this repo)

Thank you for reading, I will make some actual projects soon
