Trying to design a program in c$++$ that starts with a menu of what type of number is being inputed.

B$=$binary

D$=$decimal

G$=$grey code

H$=$HEXA

O$=$octal

A$=$ AscII

$1=1\text{'}$s compliment

$2=2\text{'}$s compliment

the goal of the program is then to take the input of the option selected, write in the input. Then generate a table of the conversions with the input at the left hand side. Sorry just trying to make sure i have things right.
