What you actually need? Its not clear. You need to create a string by concatenating two char* variable content?

Solution 1

Allocate a area of memory big enough for both the two character arrays, and use strcpy[^] - don't forget to remove any trailing null from the first, and make sure there is a null after / at the end of the second.

And why not simply use strcat()?

And C strings do not have a trailing null. It's a char with the value zero, That may sound like nitpicking, but long ago I learned that it is not safe to assume that null, NULL or whatever really equals zero.

Habit: I'm used to a char '\x00' being an ASCII null... :laugh:

Well, the new C++ standard will have you change your habits. Finally the null value is defined as part of the language.

Is there a NULLorette patch available to wean me off gently? I've been using ASCII for a very long time...:laugh:
