Difference between struct an pointer array

So lets say i have a pointer array and a struct, what in C makes struct different or they are working just the same way under the hood?

Anyway they're about the same ``under the hood'' as any other construct. Using the address of a variable just works the same way. Calling a function pointer just works the same way.
Under the hood, it's all just memory offsets.

You know there is an overhead with structs vs raw pointers vs  variables vs constants.
