Calculator 🖥️

This C progam functions as a calculator and performs 
some popular calculator arithmetic operations, 
as well as a few advanced ones. 

---

Running

• For ubuntu systems (i.e sandbox or vagrant) run the executeable file

 $- ./calculator {operation} {argument1 argument2 ...}

• For others: Run the x.sh to compile the file for your machine, then run the executeable.

 $ cat x.sh
 #!/bin/bash
 gcc calc.c -L. -lm -larithmetic -o calculator
 $ ./x.sh
 $ ./calculator {operation} {argument1 argument2 ...}

It may also be necessary to run full_compile.sh

 $ cat full_compile.sh
 #!/bin/bash
 clear
 ls
 gcc -c addition.c converter.c division.c factorial.c multiplication.c powers.c quadratic.c root.c simultaneous.c subtraction.c
 ls
 sleep 2
 ar -rcs libarithmetic.a *.o
 rm *.o
 clear
 ls
 ar -t libarithmetic.a
 sleep 2
 gcc calc.c -L. -larithmetic -o calculator
 clear
 $ ./full_compile.sh

Input Rules

To input information, follow these rules.

• Do not use a wrong data type.

 $ ./calculator root x
a

• Operations that require multiple input are seprated with a space.

 $ ./calculator add 2 3 4 5 6 7 8 9 0 13 53 75 86

• When a value is not specified as an argument, the program will exit with an error.

Functions 💻

• addition.c: A function that adds numbers, can support 2 or more numbers to be added.
  ./calculator add 2 3 4 5 ...
• division.c: A function that divides numbers. Numbers are divided using the first as numerator, and subsequent arguments are used to break it down. (i.e $ ./calculator divide 100 10 2 divides 100 by 10, then the result by 2 to give 5.
• multiplication.c: A function that multiplies two or more numbers.
  ./calculator multiply 2 3 4 5 ...
• subtraction.c: A function that subtracts a numbers.
  ./calculator subtract 131 13 12 56 1 ...
• factorial.c: A function that finds the factorial of a number(s). ./calculator factorial 2 3 4 5 ...
• powers.c: A function that finds the result of a number raised to the power of another. ./calculator power 2 3
• silmultaneous.c: A function that solves a silmultaneous equation. ./calculator simultaneous a b c d e f
• quadratic.c: A function that solves a quadratic equation.
  ./calculator quadratic a b c
• converter.c: Three functions that together convert from one base to another. (Only works for base 1-10)
  ./calculator base num current_base destination_base

Undocumented Features

• Repetition in while loop (scanf, printf, last else statements){resolved}

- Collect input(done), 
- Loop the exit and options(done, has extra features). 
- Also find a way to collect and store two return values (pending)
- Add last result (done, doesnt work for quadratic and simultaneous equations yet)
- x.sh for compiling faster
- Github actions
