d. All coding questions should be answered using the C ++ syntax. You are allowed to use the Dev-C++ compiler to write and test your code. If you do so please remember to copy and paste your code into the examination solution area. (Do NOT share your

code; your colleague could get higher marks than you!!)

Q1. Marks : 10

Write the function definitions for the following: a) A function test() that would take three integer values x, y and z (as parameters), find the largest and return the result to the calling function. b) A function sum() that would take the one integer array myArray[ ] of size 10 (as parameter), calculate the sum of the elements of myArray[ ] and display the result. Note: The function sum() returns no value.

Q2. Marks : 6

Write a program that will create and display the following series: 65, 44, 27, 14, 5, 0, -1, 2, 9, 20. Hint:

The series is created by the formula 2x2 – 3x

for x=-5 to 4

The variable x is of type integer.

Q7. Marks : 10

What will be the output of the following programs?

1. Program1

#include <iostream> int main()

unsigned short x = 1;

for (int i = 0; i < 10; i++)

cout << x << endl; x = x << 1;

return 0;

b) Program2

#include <iostream.h> int main()

unsigned short x = 1024;

while(x>=1)

cout <<x << endl; x =x >> 1;

return 0;
