Programming C

Two dimensional Arrays, String, Passing Two dimensional array as argument to function, loops

Problem Description:

Write a program that assigns the following data to a two dimensional Array then displays the Array with average of each row in a table format and the total of all element and total of elements in both diagonals.

Program first must ask for a code to continue. The code is A23bc5, case sensitive. The program must keep asking for code until the correct code is entered.

23.5 30.1 56.2 11.9

45.1 8.9 77.3 54.1

6.6 7.7 8.8 2.2

9.9 8.9 7.8 23.6

Sample output:

Avg.

23.5 30.1 56.2 11.9 30.4

45.1 8.9 77.3 54.1 .

6.6 7.7 8.8 2.2 .

9.9 8.9 7.8 23.6 ..

Total of both diagonals is: 171.6

Total of element in list: ????

Requirement

Must use two dimensional Array

Must create constants for size of the array

Must have 3 functions, one to calculate the total of all elements and one to calculate total of both diagonals (Must pass the two dimensional array to each function to do the calculation), and one to check for the correct code.

I've got this far, now im stuck
