2.1) The program in Figure 2 performs certain task. Compile the program and answer the following
questions:
a)
2.2)
b)
d)
What is the value of d?
What is the value of d if num[] is stored with {33,44,55,77,66,55,44,99,22,11}?
(2 marks)
c) What is the value of d if num[] is stored with the numeral digits of your student number?
(for example BK20123456, will be stored as 2,0,1,2,3,4,5,6)
Based on the values of d, what does the Mystery function do?

Write another program that can perform the same task. The program should be different from the
one given in Figure 2. *Copy and paste your program AND output.
int Mystery(int array[], int a, int b);
int main()
{
int a1,a2,d;
int num[] = {17,0,-61,12,200,10,69,-55,77,123,-29};
a1 = 0; a2 = sizeof(num)/sizeof(num[0])-1;
d = Mystery (num,a1,a2);
cout << "The value of d is " << d;
return 0;
