Question 3: Two-dimensional Array Given that Sale(NUM-ROWNUM-COLUMN] is a two dimensional array of float-point type and the two constants are defined as follows: #define NUMROW 4 #define NUMCOLUMN 4 - - float Value(NUM.ROWNUM.COLUMN] = 5.1, 5.2,5.3,5. 1.9, 2.0, 2.1,2.2, 2.1, 2.2, 2.3, 2.4 Write a C++ main function that computes and prints out the following information about this 2d array: (1) The mean of all the array elements. (2) The local difference values of a the array elements. For instance, the local difference value at position i,j- max(Value[i-1]i], Valuei+1]], Valuei,Valueij- min(Value[i-1]j], Value[i+1]i, Value[i],Value[i]i-1], where max() and min) are two functions that return the maximum and minimum of four arguments. If (iH) > NUM-ROW-I or (i-l )
