does what you expect it
to.
Question 1: [30 marks/
Use the following function interface:
void rev erse_stack(stackint>& S. stackini>& St slackcint>& 82).
and
write a C++ function that rev erses the order of elements on stack S using two additional
slacks SI and S2. Do not use the assignment
operator anywhere in your code. A
good format for testing your function is the following:
slackcint> S, SI . 52:
Sp S.push(2),
soul « he top element of S -« S.top0 « endl:
rev erse stack(S. St. S2);
tout «’The top element of S is now ‘ «
StopQ « endl;
Submit only the code for this function (no drivers please) in a file called assignment3 function scc.
Question 2: pc,
marks(
Use the function interface:
double sum(int n).
to write a recursive function (i.e., no loops are to be used) to add the first n
terms of the series
I+
1
2
3
4

and return the value of that sum. Make sure to test that your function
gives the correct outpud
Submit only the code for this function (no drivers please) in the file assignment3 functions.cc.
as for Question
1.
Question 3: [40 marks(
Consider the following function:
void iterative_callQ
int call = 1:
string statement = This was written
by call number
4
5
and return the value of that sum. Make sure to test that your function gives the correct output! Submit only the code for this function (no drivers please) in the file assignment3 functions-cc. as for Question I. Question 3: (40 marks] Consider the following function: void iterative_call() int call = 1; string statement = Thiswaswritten by call number for (; call != 5; ++cal0 tout « statement « call « endl; statement = “+ + statement; 11 adds leading white space ) for (– call; call I= 0; –call) cout « statement erase(0.1) « call « endl; // removes leading white space Rewrite this as a recursive function (i.e., no loops are to be used) using the function interface: void recuisive_call(int call = 1). so that calling recursive call() gives exactly the same output as calling iterative call° Note that the default argument will be set to call = 1 in the first function call. You might find the keyword static to be useful. Submit the code for this function in assignment3 functions.cc. as for Questions 1 and 2.
