Associative Array Template in C++

This repository contains a simple implementation of an associative array template in C++. It demonstrates how to define and implement a template class in C++ for creating and managing an associative array, which is a collection of key-value pairs. This project is structured into a header file, a template implementation file, and a main driver program.

Project Structure

  • associative_array.h: Header file containing the template class declaration for the associative array.
  • associative_array.tpp: Implementation file for the template class. This includes the definitions of the member functions declared in the header file.
  • main.cpp: Main driver program that demonstrates the usage of the associative_array template class with different operations.
  • Makefile: A simple Makefile to compile the project using g++ and generate an executable.

Features

The associative_array template class supports the following operations:

  • Insertion and retrieval of elements based on a key.
  • Automatic creation of a new element if the key does not exist when accessed.
  • Exception throwing if a non-existent key is accessed in a const context.

Compilation and Running

Ensure you have a C++ compiler that supports C++17 (or later) installed. This project was tested with the GNU compiler.

To compile the project, simply run:

make

This will generate an executable named associative_array. You can run this executable to see the associative_array class in action:

./associative_array

To clean up the compiled files, you can use:

make clean

Usage Example

The main.cpp file demonstrates how to use the associative_array class with std::string as the key type and int as the value type. It includes operations like inserting elements and attempting to access elements with both existing and non-existing keys.
