C language function to calculate maximum contiguous points that can be placed in a pattern

I have a project that requires writing a C language function that will calculate the maximum contiguous points that can be placed in a 2D array of variable size. The maximum number of points to be placed in the pattern depends on the pattern. I'm looking for experienced coders who are skilled in C programming and can help me develop an effective function for this task. Please apply if you have the relevant experience and expertise. Thank you!
