Sample Qustion 10

Write a C++ program to display
             a. Smallest value in each column
             b. Smallest value in each row
             c. Largest value in each column
             d. Largest value in each row
             e. Overall smallest value and largest value
             f. Column name of the overall largest       
                     value
                               Use the give 2D array.
