variable: value type lives on the stack, reference type lives on the stack as a pointer to somewhere in heap memory where the actual memory lives
class/struct-field: value type lives inside the class, reference type lives inside the class as a pointer to somewhere in heap memory where the actual memory lives.

Also if any structure is declared in a function, the
function stack creates a heap from the stack. so these
structures in function allocates in heap.
