I a bit of code I've been writing I've got some structs. (Normally I use classes, but this code is in c and not c++.)

And at one point in my code I have code like this (simplified to shorten explanation):


But not everything gets shunted on and off the stack correctly. I realize arrays like 'c' should not, but some values like 'd' and 'e' just don't for some reason. What I mean is, when I use '=' to transfer the structs values a and b might copy but d and e won't. It's weird, because it's always the same items in the struct but they appear to be initially chosen at random. I'm not sure why.

I'm gonna make a function to copy my structs, but I'm curious why this is happening.

Thank!

There's nothing inherently wrong with the code you've posted. The assign will do an exact bitwise copy (likely actually call memcpy with a struct that large). Even the content of C will be copied, since no pointers are involved.

Weird, I must have modified my values wrong or something.

Thanks!
