 Logical processing
 Dealing with Data types
 Writing and editing a C program

Guidelines
 Code should be properly aligned and well commented.
 Follow c/c++ rules while writing variables names, function names etc
 Use only dev-C++ for this assignment.
 Use appropriate c/c++ structure i.e. if-else, switch statement etc to get inputs from user.(Marks will be deducted if inappropriate structure will be used).


Assignment

Problem Statement: Sorting two matrices

You are required to write a program which takes two 3x3 matrix A and B containing 09 elements each and sort all these 18 elements in descending order and put it in one dimensional array and then display it.

Follow the following steps to code this program
1. Take two two-dimensional arrays as A[3][3]and B[3][3] and one-dimensional array C[] to keep the result.
2. Prompt the user to enter the elements of first matrix
3. Prompt the user to enter the elements of second matrix
4. Now take first element of first matrix and check in both matrix weather it is greatest or any other number is the greatest and put the greatest number at the first index of the one dimensional array. Follow this procedure for other elements and at the end one dimensional array would be in descending order
5. Display this one-Dimensional sorted array on the screen


Following is the sample program structure


2 3 5 2 8 7
A= 6 5 9 B= 0 1 1
1 0 2 4 7 9


Output should be like this

Please enter the Elements of First Matrix:

Please enter the Elements of second Matrix:

Sorted Values from Both the Matrices are:
-----------------------------------------------------------------
9 9 8 7 7 6 5 5 4 3 2 2 2 1 1 1 0 0

-----------------------------------------------------------------

Note:
Your assignment must be uploaded/submitted on or before May 2nd, 2011. Make it sure to submit only Cpp file of your Assignment. Assignment in notepad format or MS Word format will not be accepted.
