salamangkero thanks a lot.... and osknockout i don't know how to write this statements in programm ''Then character n+1 must have index less than or equal to i+2, say it has index j in the array. If j > i, then it is a standard roman numeral iff (if and only if) the preceding character was C,X, or I.'' ?? and i'm sorry for being such boring...

THANKS...but that's not enough...e.g. if i input XXXLCIM that isn't a roman number,but has characters from the set ''I,V,X,L,C,D,M''...so....?

hy.... i really need help... we have to make a programm that checks if input string is roman number...and i'm beginner in c/c++so i don't really know how to do this.... so if anyone can help me,please.... THANK YOU....
