What is stack frame and local variable?
The stack is used for dynamic memory allocation, and local variables are stored at the top of the stack in a stack frame. A frame pointer is used to refer to local variables in the stack frame.What variables are in stack frame?
A stack frame is comprised of:
Local variables.Saved copies of registers modified by subprograms that could need restoration.Argument parameters.Return address.Can local variables be stored in stack?
Local variables (i.e. those that are declared inside methods) are stored on the stack. This means their values are stored on the stack, therefore meaning that local reference type variables have references stored on the stack and local value type variables have actual values stored on the stack.- The stack behaves as a space for temporal annotations. For example, when a function is invoked, its local variables are only active during its execution. When the function terminates, these variables do not exist any more.
