Challenge: Type-Based Addition and Type Information

Apply the knowledge you gained in this section to solve the type-based addition and type information challenge.

We'll cover the following

Problem statement

Handling operations on similar types in a type-safe manner is critical for building robust applications. You’re tasked to implement a function called type_based_addition that performs addition based on the types of its arguments. The function should be able to handle a variety of input types, including integers, floating-point numbers, strings, etc. Additionally, implement a function get_type_info that takes a variable and tells the type of that variable. To achieve this, you need to use the knowledge you have gained so far, especially the type traits and conditional compilations.

Note: Create or reuse any auxiliary functions needed to solve the challenge.


We can extract the following information from the problem statement:

  • The type_based_addition function is expected to have the following behavior:

    • The function should return the sum if the input arguments are integers, floating-point, or double numbers.

    • The function should concatenate the input arguments if they are strings.

    • If the input arguments are pointers of types convertible to std::string, then the function should concatenate the dereferenced pointers.

  • The get_type_info takes variables of any type and prints their types, values, and the output of their sum on the console.

Let’s use the illustration below to exemplify the required functionality.
