• False

What do you understand by:

• update is a method that takes structure type variable as parameter

• Error, we cannot pass structure variable as pointer to a function

• update takes pointer argument but it cannot return void

Local variables are stored in an area called____________

• Heap

• Permanent storage area

• Stack

• Free memory

The size of both stack and heap remains the same during run time.

• True

• False
