Can anyone give me somewhere to start if
I have to convert from Roman Numeral to decimals?
M - 1000
D - 500
C - 100
L - 50
X - 10
V - 5
I - 1
that if the user inputs CD - 400
MD - 1500
IX - 9
MXIII - 1013
I just need a rough guide on how to do this.
All I know is if the digit's value before is smaller, then subtracts and if not, just keep adding. any example would help me greatly. thanks.
PS: how do I also make the scanf determine the number of letters input?
