Question

3. Show the stack with all activation record instances, including static and
dynamic chains, when execution reaches position 1 in the following
skeletal program. Assume bigsub is at level 1.
function bigsub() {
function a(flag) {
function b() {
***
a(false);
} // end of b
***
***
if (flag)
b();
else c();
} // end of a
function c() {
function d() {
<---
***
} // end of d
d();
} // end of c
***
2
a(true);
} // end of bigsub
The calling sequence for this program for execution to reach dis
bigsub calls a
a calls b
12

d();
} // end of c
MIM
a(true);
} // end of bigsub
The calling sequence for this program for execution to reach d is
bigsub calls a
a calls b
b calls a
a calls c
c calls d

Scala programming
Stack ADT Implement a program in C++ that has the following three parts and each does the following: 1. Implements in C++, the specification of a Stack ADT with all the Main and Helper behaviors (save the file as StackADT.h) 2. Implements in C++, all the necessary methods (behavior) of the StackADT (save the file as StackADT.cpp) 3. Implements in C++, a main function (the client or application program) that creates and uses Stack objects (save the file as StackMain.cpp). This main function should be able to do the following: a. It should be able to read a given text file as input, b. It should be able to get each input value from the input file (one word at a time) and store it (push) on the StackADT object until it stores all the words from the input file. c. It should be able to retrieve an item from the stack and 1) display it on the screen, as well as 2) write it to an output file, and then delete (pop) that item from the stack, and repeat this process until it retrieves all the…

What makes the restricted implementation of the stack different from the unbounded implementation of the stack?
Assume class StackType has been defined to implement a stack data structure as discussed in your textbook (you may also use the stack data structure defined in the C++ STL). Write a function that takes a string parameter and determines whether the string contains balanced parentheses. That is, for each left parenthesis (if there is any) there is exactly one matching right parenthesis later in the string and every right parenthesis is preceded by exactly one matching left parenthesis earlier in the string. e.g. abc(c(x)d(e))jh is balanced whereas abc)cd(e)(jh is not. The function algorithm must use a stack data structure to determine whether the string parameter satisfies the condition described above. Edit Format Table 12pt v Paragraph v |BIU A v ev T?
