Programming Exercise 1: Passing a Two-dimensional Array
Write a program that will read in 12 integer values into a 3 x 4 two-dimensional array (i.e., an array of 3 arrays of 4 integers). The values should be entered via standard input. The main program should then call a function sum that will calculate the sum of the values and return this sum back to the main program. The main program will output the sum. This program shows that you can successfully pass a two-dimensional array in C.

Programming Exercise 2: Inner Product of Two Arrays
Write a program that will input two arrays of information. Each array will contain exactly 4 floating point values. Your program will enter these values from standard input. Once the values have been read in, your program should call a function that will compute the inner product of these two arrays. The function should return the value back to the main program. The main program will then print out the value. You should not print the value out inside the inner product function. The inner product of two arrays is a single number obtained by multiplying corresponding elements and then adding up their sums.

E.g., if array u = (5, 1, 6, 2) and array v = (1, 2, 3, 4) then the inner product is 33
because (5 * 1) = 5 (1 * 2) = 2 (6 * 3) = 18 (2 * 4) = 8
and 5 + 2 + 18 + 8 is 33.

Your main function will call a function called inner that has the following declaration:
float inner ( float u[], float v[], int size ) ;

Programming Exercise 3: Unfilled Box
Your task is to read a pair of positive integers, L and H (in this order), from standard input. Both L and H will be less than 21. Your program then prints out an empty box of asterisks with L horizontal stars and H vertical stars. The box is empty. For example, if the input data is 6 and 4 then the output should be:

******
*       *
*       *
******
The minimum values of H and L will be 1. Your program must output a 1 × 1 box correctly when prompted.
