“I need a C class that has a constructor for a tuple”

I would hope Claude would be like “Hold on man…”

Hm. That was interesting, so I ran it as prompt to Qwen3-Coder (which I run locally). It spat out a bunch of C functions together with a C struct and commented:

  This implementation provides:
  Generic Tuple Structure: A flexible tuple that can hold different types of elements (int, double, string, float)
  Constructor Function: tuple_create() initializes a new tuple with specified size
  Type-Safe Setters:
    tuple_set_int(), tuple_set_double(), tuple_set_string(), tuple_set_float()
  Type-Safe Getters:
    tuple_get_int(), tuple_get_double(), tuple_get_string(), tuple_get_float()
  Memory Management: Automatic memory allocation and deallocation
  Utility Functions:
   tuple_print() for displaying tuple contents
   tuple_destroy() for cleanup

I asked ChatGPT to make a system of macros that would generate a struct with given fields (for example: int a, bool b, char *c) and a function that would print the struct contents. Instead of refusing it started inventing recursive macros that were never going to work. It seems LLMs are especially bad with C macros.

If you have access to state-of-art coding assistants, try asking this. You can additionally add a requirement to generate a destructor function (that would free dynamically-allocated fields).

| I'll create a simple C++ class with a constructor that takes a tuple. Here's an example...

| C doesn't have classes or constructors - those are C++ features. In C, you would use a struct and create an initialization function. Here's how you'd handle a tuple-like structure:
