converting strings to char

Is there a way that you can convert a roman numeral to a decimal number? for example is there a way to break a string into 1 letter at a time so I can verify 1 letter at a time so I can put it in a casestatement

Sure, you can do that.

Code:

---

char *lpString = "Hello World";

char firstChar = *lpString;
char secondChar = *(lpString + 1);

switch( firstChar )
{
  case 'X':
  case 'x':

    // blah..
    break;
}

That code does nothing but you should get the idea how to walk through a string. You have a pointer to a series of characters. When you dereference the pointer you get a single character. So to get the second character I add one to the pointer address and then dereference. Hope that helped.

EDIT:
You'll want this in a loop and you'll want to check for the '\0' character because strings are null-terminated.

If you are using type string, you can use index operator [].

Code:

---

string str = "Hello Word!";

char first = str[0].

I was not aware you could use the index operator on a string type. I am glad I read this thread ;)

do a board search. Roman numeral conversions crop up quite often.
