Notation Converter

Class for converting from one arithmetical notation to another.

Notation types

• Prefix
• Infix
• Postifx

Installation and testing

It is one header class, so just include appropriate file named notation_converter.h in inculde/ directory.

To run the tests(assuming you are in the root repository directory):

mkdir build  # or mybuild
cd build
cmake ..
make
./run_tests

Using in your project

From previous step you can find static library generated in build directory. File named libnotaconv.a is a static library. So you should link this to your cpp-program and also add an include path which is include folder in the project's root.

Manually

// use.cpp

#include "notation_converter.h"

#include <iostream>

using namespace notaconv;

int main() {
    NotationConverter nc {"+ 1 1", ArithmeticNotation::PREFIX};
    std::cout << nc.convert(ArithmeticNotation::INFIX) << '\n';
}

And compile-link-run it like this(gcc example):

> g++ use.cpp -I"${PROJECT_DIR}/inculde" ${PROJECT_DIR}/build/libnotaconv.a -o use
> ./use
> 1 + 1

Where ${PROJECT_DIR} is a path to this project's directory.

CMake

Add this lines to your CMakeLists.txt:

include_directories(${NOTACONV_PROJECT_DIR}/include)
link_directories(${NOTACONV_PROJECT_DIR}/build)
...
...
...
target_link_libraries(executable notaconv)

Where ${NOTACONV_PROJECT_DIR} is a path to this project's directory, and executable is your target specified in add_executable(executable ${SOURCES}) function call.

How to

For user there are to main classes in this project:

1. NotationConverter
2. ArithmeticNotation

Second one is just enum class denoting one of types of notation. And the second is a converter. Use it like this:

#include <iostream>
#include <string>

#include "notation_converter.h"

using namespace notaconv;

std::string expr {"1 + 2 * ( 3 - 2 )"}; // necessary to have a space between two items
NotationConverter nc {expr, ArithemticNotation::INFIX};

std::cout << nc.convert(ArithemticNotation::PREFIX) << '\n';    // "+ 1 * 2 - 3 2"
std::cout << nc.convert(ArithemticNotation::INFIX) << '\n';     // "1 + 2 * ( 3 - 2 )"
std::cout << nc.convert(ArithemticNotation::POSTFIX) << '\n';   // "1 2 3 2 - * +"

This repository is a pet-pet project to learn TDD.
