"sum += *(arr+i*seconLength+j);"

This solved the problem.. Thanks... But I still dont get what part i*seconlength+j takes in this code.

As I understand, in the first round of the first loop and, the first round of the second loop..

arr+i = arr[0] element
arr+i*seconLength = arr[0] element
arr+i*seconLength+j = arr[0] element..

As I see, this line doesn't care about the 2nd dimension of the array..
Can u please explain some further how this retrieve values from the arr[0] and arr[1] array ?

Thanks..

Value-specific class bodies
In addition to defining a class body for the enumerated type itself, you can also
provide a class body for individual enumerated values within the type. We’ve seen
above that we can add fields to an enumerated type and use a constructor to
initialize those fields. This gives us value-specific data. The ability to define class
bodies for each enumerated value means that we can write methods for each one:
this gives us value-specific behavior. Value-specific behavior is useful when
defining an enumerated type that represents an operator in an expression parser or an opcode in a virtual machine of some sort. The Operator.ADD constant might
have a compute() method that behaves differently than the Operator.SUBTRACT
constant, for example.

To define a class body for an individual enumerated value, simply follow the value name and its constructor arguments with the class body in curly braces. Individual values must still be separated from each other with commas, and the last
value in the list must be separated from the type’s class body with a semicolon: it
can be easy to forget about this required punctuation with the presence of curly
braces for class and method bodies.
