Expert Solution & Answer
Chapter 5, Problem 11RQ
Explanation of Solution
Static-dynamic variable:
A variable that is allocated statically and the lifetime of which extends across the entire runtime of the program is called a static variable.
Stack-dynamic variable:
A stack-dynamic variable is bound to the machine memory after the declaration statement has been executed and is deallocate after the procedure returns.
Advantages and disadvantages of stack-dynamic variables:
Memory from the run-time stack is allocated for stack dynamic variables. ALGOL 60, FORTRAN 77 and FORTRAN 90 use stack-dynamic variables. In C and C++ all local variables are by default stack-dynamic variables.
Explicit heap-dynamic variables:
Explicit heap-dynamic variables are anonymous memory locations in the machine memory that are allocated or deallocate by the explicit instructions from the programmer. These are generally referenced through a pointer or a reference.
Advantages of explicit heap-dynamic variables:
Explicit heap-dynamic variables make it more convenient to construct dynamic structures, such as linked lists and trees, whose elements grow and decrease during execution of the program...
