Question

I'm looking for a simple code to develop a" Magic Square 4*4" that uses two "dimensional arrays" and " loops"!! I have been working on one , but still stuck on that, it would not give me the right output !!

Help please!!

here is the question:

const int MAX = 4;

int sumRow (const int square[], int row);
// Precondition: square is an initialized matrix, MAX rows x MAX columns
// 0 <= row < MAX
// Postcondition: returns the sum of the values in row

bool unique (const int square[])
// Precondition: square is initialized with integers.
// Action: Inspects every value in square, checking that each one is a unique
// integer ranging from 1..MAX*MAX
// Postcondition: Returns true if each value is unique from 1..MAX*MAX,
// otherwise returns false
