Code Explanation:

• The Column template class represents a DataFrame column capable of storing data of any type.
• The DataFrame class mimics the functionality of a Pandas DataFrame but uses a map to store column data as strings.
• The DataFrame::add_column member function template allows adding columns with different data types to the DataFrame.
• Internally, all data is converted to strings for uniform storage, but when retrieved through get_column, it’s converted back to the requested type.
• DataFrame::display prints out column names followed by their string-converted data.
• In the main function, a DataFrame object is instantiated, and columns of different types are added.
• The DataFrame is displayed to show the contents, and a single column is retrieved and manipulated (squared integers are printed).
• Exception handling is in place to catch and report errors, such as requesting a non-existent column.
