C/C++ :: Writing And Sorting Student Report

I'm trying to write a table (2D array) with a string of random chars in one row for the student names, six other rows for the project numbers and random numbers for the grades.Then calculate the averages of grades per student and per project, add them as the last row and the last column. And write a menu of 4 options:

1- sort per student names (alphabetical order)
2- sort per student grades (in increasing order)
3- sort per project grades ( in increasing order)
4- exit

The program must continue execution after displaying any report, need to use an infinite loop, it exits only if the chosen 'exit'.

Here's what I have:

#include <ctime>
#include <string>
#include <iomanip>
#include <iostream>
using namespace std;
ints=12,p=6;
stringnames[20];

[Code] ....

And then, I need to show interactively the same report with all types of sorting:

sort table by any row, (user enters the row number)

sort table by any column. (user enters the col number)

sort table sorted by student names as well.
