I have following code snap written in VC++ 6.0
if ( sscanf( p,"%02x",&ID ) != 1 )
printf("ID = %d\n",ID);
If p = tt or TZ or Za or R5 it returns error but 4T or 7G does not.
What change do I need to make to return error even for 4T and 7G?
That is, I want to return error if any of the character is non-numeric.
