// The "TwoDimensionalArrayTable" class.

//NAME: CLINTON SHEPLEY

//DATE: SEPTEMBER 18

//PROGRAM DESCRIPTION: Two dimensional array are tables with rows and columns

//from page 361 in the java book, adapt the program to use r for the

//first loop and c for the second loop change the nested loop for marks input

//Improve page 361 by adding a single dimension array for names.

 

 

//assign values to the array
