Q. The order in which the return addresses are generated and used is
✅ Correct Answer: (A)
lifo
Explanation: that is the routine called first is returned first.
Q. In case of nested subroutines the return addresses are stored in
✅ Correct Answer: (C)
processor stack
Explanation: in this case, there will be more number of return addresses it is stored on the processor stack.
Q. The appropriate return addresses are obtained with the help of in case of nested routines.
✅ Correct Answer: (D)
stack-pointers
Explanation: the pointers are used to point to the location on the stack where the address is stored.
Q. When parameters are being passed on to the subroutines they are stored in
✅ Correct Answer: (D)
all of the mentioned
Explanation: in the case of, parameter passing the data can be stored on any of the storage space.
Q. The most efficient way of handling parameter passing is by using
✅ Correct Answer: (A)
general purpose registers
Explanation: by using general purpose registers for the parameter passing we make the process more efficient.
Q. The most Flexible way of logging the return addresses of the subroutines is by using
✅ Correct Answer: (B)
stacks
Explanation: the stacks are used as logs for return addresses of the subroutines.
Q. The private work space dedicated to a subroutine is called as
✅ Correct Answer: (C)
stack frame
Explanation: this work space is where the intermediate values of the subroutines are stored.
Q. If the subroutine exceeds the private space allocated to it then the values are pushed onto
✅ Correct Answer: (A)
stack
Explanation: if the allocated work space is exceeded then the data is pushed onto the system stack.
Q. pointer is used to point to parameters passed or local parameters of the subroutine.
✅ Correct Answer: (B)
frame pointer
Explanation: this pointer is used to track the current position of the stack being used.
