I'm actually working on a library doing just that! It's still in very (very) early development, but maybe someone may find it to be interesting. [GitHub](https://github.com/jenspots/libwheel).

[Here](https://github.com/jenspots/libwheel/blob/main/include/wheel... the implementation of a vector. [Here](https://github.com/jenspots/libwheel/blob/main/tests/impl/st...) is a test file implementing a vector of strings.

const int myarray[mysize];

* Good news: C can do compile time constant structs and array with deep self-references.

Yes, in C you can define and fully declare complex data structures that are accepted as compile-time constants, including pointers to parts of itself.

See "self-contained, statically allocated, totally const data structure with backward and forward references (pointers)?" for a previous example at https://stackoverflow.com/questions/47037701/can-c-syntax-de...

-----------------

I used this for a game on a retro machine where such a data structure avoids code which would have been several times (perhaps 10 times) bigger: https://github.com/cpcitor/color-flood-for-amstrad-cpc/blob/...

Here's another take showing two variant: where overall construct is an array then a struct: https://gist.github.com/fidergo-stephane-gourichon/792c194e1...
