Create a new string before using strcpy?

A little chunk of code:
ClassGFX already has a char *Name;.

Code:

---

ClassGFX::ClassGFX(const char *NewName, int Num)
{
  char TempString[50]="GFX/";
  Name=new char[strlen(NewName)];
  strcpy(Name, NewName);
  strcat(TempString,NewName);
}

---

Is the command to create a new string for Name necessary, or will strcpy take care of that? Also, is that TempString correct, or do I have to add a /o after it to end it? (btw, I'm going to do some more with the TempString later)

>Is the command to create a new string for Name necessary, or will strcpy take care of that?

you must do it! strcp() expects there to be enough space!

>Also, is that TempString correct, or do I have to add a /o after it to end it?

when you initialize it that '/0' is added automatically, most of the std library functions that act on strings add the '\0' themselves but explicitly adding if your not sure is not bad practice.

>Is the command to create a new string for Name necessary, or will strcpy take care of that?
Yes.

> Name=new char[strlen(NewName)];

This should be:
Name=new char[strlen(NewName)+1];

OK, I got it.
Thanks!
