This is a simple interpreter to calculate arithmetic expression referenced from Ruslan's Blog.
$ make main
- This interpreter can execute mathematical expressions like '34+7-5+3' or '2 * 52 / 8', etc.
- The supported operations are addition (+), subtraction (-), multiplication (*), division (/), power (^)
- The operations are executed from left to right, i.e. the interpreter doesn't give priority to multiplications, etc.
- Support Precedence and Parentheses.
- Number in the interpreter is handled with integer, so error exists when expression has float-point operation.
