Question

Stackoverflow users!
I am using Borland C++ Builder 6 for creating my program. Yes, I know that it is outdated for last two millon years, however, I have to use this IDE. I have a String which I need to split. So I use the following method:

void Orders::split(TStringList* lout, char* str, const char* separator) {
  for(char* tok = strtok(str, separator); tok!=NULL; tok = strtok(NULL, separator))
      lout->Add(tok);
}

Also, I have a separator defined as a preprocessor constant:

#define SEPARATOR ':'

Then I call the split method

split(ords, input.c_str(), SEPARATOR);

And I get the following error:

[C++ Error] File3.cpp(47): E2034 Cannot convert ‘int’ to ‘const char *’

On the line, where I call the split method. Casting to const char* leads to the same result. Is there a bug in the IDE or am I just too dumb to see my own error in code?
Thanks in advance!

Answer 1

strtok is looking for a const char* as delimiters. Try defining it like this instead:

#define SEPARATOR ":"

This is because you can specify a set of delimiters, so that strtok stops if any of those characters is found.
