Need codes for sorting array on the screen

You are required to write a program which takes two 3×3 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 whether 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.

Sample is here

   2 3 5                  2 8 7

   A=6 5 9             B=0 1 1

   1 0 2                  4 7 9
