It's urgent!!!! I want a help with this c++ program!!!

Write C++ statements that allow you to print part of the contents of the array, namely, the cells in the diagonal from bottom to up as shown using the arrow below. The array is a[max][max] is already declared and initialized with values in main(). For example if max = 0 and the array a has values in the diagonal as shown below, the C++ statements will print 8, 4, 3, 5, 6, 1
