Should I convert FORTRAN code to C?

Ok, what gives. Some else post the following code (not exact but close enough)

	real a(5,2)
	...
	call foo(a)
	...
	end

	subroutine foo(a)
	real a(10)
	...

Now doesn't the following c code work to do the same

	double a[2][5]        /* <-- note [2][5] not [5][2] */
	...
	foo(a)
	...
	}

	void foo(a)
	double a[10]
	{

If it is not the same, would someone please post or email a counter
example. I would like to see what is wrong.

Note there are problems if you dynamicly allocate arrays but you cannot
dynamicly allocate arrays in fortran so this is a void arguement.
