### C Program to sort the matrix rows and columns.

C Program to sort the matrix rows and columns. This C program accept a order MxN Matrix, and sort all rows of the matrix in ascending order and all columns in descending order . In this program, we use the for statement to read two dimension arrays. Read more about C Programming Language .
