| | Observation: string.h is a standard C header file -- rename yours to something else to avoid filename clashes. In MS-Windows file names are not case sensitive like they are in *nix, so String.h is the same file as string.h, which is clearly not what you want because your program is … |

| | std::string's find() method then use std::string's substr() method to extract the string. IMO its better than strtok() because it doesn't modify the original string. If you were using c++/CLR then it's String class has a Split() method, but that isn't standard c++ and works only with Microsoft compilers. |
| | The new c++ standards, which will not be released for some time yet, is supposed to allow arrays to be allocated like that: [icode]int ay[size][/icode] where size is not a const integer. A few compilers may already support it, but if they do it is compiler-specifc. |
