C++ :: Program That Uses Recursion To Find Longest Increasing Sequence From A Grid In File

Any examples of a c++ program that uses recursion to find the longest increasing sequence from a grid in a file. Like

2 4 6 8
10 12 14 16
18 20 22 24

I have to use a structure named Point and a structure named Sequence.

const int MAXROWS = 4;
const int MAXCOLS = 4;
const int MAXFILENAME = 255;
// Structure used to define a point (x,y) in the grid.
typedef struct {
int x, y;
