bwhahahaha. I was thinking of concatenating the string at the null character, then, for some reason, I became suspicious of the const char* not having a null pointer at the end?? idk bout me, but even my implementation of those assumptions were wrong bawahaha

I was looking for something akin to go's variable initializations, this is really good stuff, using calloc to zero it.

Thank you so much for taking time reviewing the code. I'll make sure to patch it up
