The cell can hold three modes: (possible empty) text, a numerical value, or a formula. Its mode is stored in the cellMode field. It can hold the value TextMode, ValueMode, or FormulaMode.

HeaderWidth, HeaderHeight, ColWidth, and RowHeight are the size of the headers and cells of the spreadsheet. In order for the cell text to not overwrite the cell's borders, CellMargin is used. The spreadsheet is made up of ten rows and four columns.

Cell.h

extern const int HeaderWidth, HeaderHeight, 
                 ColWidth, RowHeight, CellMargin; 
 
#define Rows 10 
#define Cols 4

enum Alignment {Left, Center...
