{

unsigned short int x, y;

x = 7;

y = myFunc(x);

std::cout << “x: “ << x << “ y: “ << y << “\n”;

return 0;

}

int myFunc(unsigned short int x);

{

return (4*x);

}

5. Write a function that takes two unsigned shortinteger arguments and returns the
   result of dividing the first by the second. Do not do the division if the second num-
   ber is zero, but do return –1.


6. Write a program that asks the user for two numbers and calls the function you
   wrote in Exercise 5. Print the answer, or print an error message if you get –1.


7. Write a program that asks for a number and a power. Write a recursive function
   that takes the number to the power. Thus, if the number is 2 and the power is 4, the
   function will return 16.
