Problem Statement
Write a program that allows the user to repeatedly enter positive integers to be converted
into the Roman number system until the user enters -1 to exit the program.
The$Roman$number$system$has$digits:$
M 1000
D 500
C 100
L 50
X 10
V 5
I 1
Numbers$are$formed$according$to$the$following$rules:$
• Only$numbers$up$to$3999$are$represented.$
• As$in$the$decimal$number$system,$the$thousands,$hundreds,$tens,$and$ones$are$
expressed$separately.$
• The$numbers$1$to$9$are$expressed$as$
$I 1
II 2
III 3
IV 4
V 5
VI 6
VII 7
VIII 8
IX 9
As$you$ can$see,$ an$I$ preceding$a$ V$or$X$ is$subtracted$ from$the$ value,$and$ you$
can$never$have$more$than$three$I’s$in$a$row.$
$
• Tens$ and$ hundreds$ are$ done$ the$ same$ way,$ except$ that$ the$ letters$ X, L, C$
and$C, D, M$are$used$instead$of$I, V, X,$respectively.$
