Thread: program that offers choice of tool width

I need help writing this program:

1)The program will offer a choice of a tool width of:
A 0.1 mm
B 0.3 mm
C 0.5 mm
D 1.0 mm

2) Request the input of a position in 2D within the boundaries of -10000<=X<=+10000 and 0<=Y<=3000

3) Print the XY coordinates in steps of the chosen tool width to plot the first letters of your first and family name within a rectangle of X=200 and Y=100. Make sure not to violate the boundaries of (3).
