Sure...

VB Code:

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
Function sumFirstLast(number As Integer) As Integer
 
Dim numberString As String
 
numberString = Abs(number) & ""
 
sumFirstLast = Val(Mid(numberString, 1, 1)) + Val(Mid(numberString, Len(numberString), 1))
 
End Function
Function sumFirstLast(number As Integer) As Integer

Dim numberString As String

numberString = Abs(number) & ""

sumFirstLast = Val(Mid(numberString, 1, 1)) + Val(Mid(numberString, Len(numberString), 1))

End Function

what? WHAT?

or, in C++,

 C++ Syntax (Toggle Plain Text) 
int sumFirstLast( int n )
{
    char s[32];
    return ((n % 10) + (*itoa(n,s,10) - '0')); // itoa converts an int into a string
}
int sumFirstLast( int n )
{
    char s[32];
    return ((n % 10) + (*itoa(n,s,10) - '0')); // itoa converts an int into a string
}
