BARES Project

Title came from Basic Arithmetic Expression Evaluator based on Stacks

Objectives

This project consists on the implementation of a simple expression calculator using concepts of stack and array in a real context application. The program needs to be able to recieve simple arithmetic expressions made of:

• Numeric constants (-32.768 to 32.767).
• Operators (+, -, /, *, ^, %), with their correspondant priority.
• Delimiters ((), [], {} ).

Dependencies

You need git to clone the repository, make and g++ to compile the program. To install these dependencies, you just have to use your package manager, such as a debian based distro:

sudo apt-get install g++ git make

Compile

To compile the project, first you need to clone the repository, enter in directory with

git clone https://github.com/felipecramos/bares.git; cd bares

And then, type make on project root.

Execute

You can execute bares by using std::cin or reading and writing expressions with shell streams.

Example on unix based systems:

./bares < input_file > [output_file]

And even execute and type successively expressions ended by <CR> and then press ctrl-d to stop reading and show the results.
