Study the wonderful C Tutorial linked at the top of this forum. It has all the info you will need for a much better understanding of C - including C array declaration syntax.

I already know the syntax, but in this question I am not getting

Its the question which I came across while solving MCQ, its not the question given by my instructor

The question is about the number of elements you can store in that array.

So, how many elements are in the first dimension (-1...m)?
How many elements are in the second dimension (1...m)?

If you know both numbers it shouldn't be hard to declare the array in valid C-Syntax.

A(-1..2 , 1..2 )

I am still confused about the declaration , how to run this and know the output

It's a psuedo code declaration. The first index of A goes from -1 to +2 and the second index of A goes from +1 to +2. So how many elements are there in A?

Thanks a lot you solved my query answer is m(m+2), you had given me the hint that I was looking for, thanks once again
Solution if m=2 then -1,0,1,2 and 1,2 so we get Two dimensional array A[4][2], so there are 2(2+2)= 8 elements in array

I think I am 100% right but if somebody thinks that I am WRONG somewhere then they can correct me
