vvitali / advanced-calculator-of-expressions-with-variables

Software project in C language: calculation of expressions ( Arithmetic: + - * /) with numbers and variables. Full execution and step-by-step tracing. Based on "Shunting-yard algorithm" with reverse polish notation. Program reads expressions, and variables from user-defined text-file, and write results to another user-defined text-file. Project has a text user interface with box-drawing character.

Advanced calculator of expressions with variables

Software project in C language: calculation of expressions ( Arithmetic: + - * /) with numbers and variables. Full execution and step-by-step tracing. Based on "Shunting-yard algorithm" with reverse polish notation. Program reads expressions, and variables from user-defined text-file, and write results to another user-defined text-file. Project has a text user interface with box-drawing character.

Program will ask you 2 things:

1. Input file: you can use standart text files (*.txt, or just *)
2. Output file: you can use any names what you want.

Also you have to choose execution mode:

1. Full execution - here you will see just a result of expression.
2. Tracing mode - in this case program will show you step-by-step process with intermediate results and values of variables.
