wxString::Printf()

<< < (2/3) > >>

Balazs:
If printfs work, there is no reason to change.
Also, as a Hungarian, I can tell, that most often the whole sentence needs to be restructured often to get a meaningful translation, and with <<, this is impossible.

Besides, what would be the advantages of <<? Is it a 100-times faster or what? :roll:

The standard C printf is not type safe and you can crash your program by telling printf you are giving it one kind of variable and passing it another.  So the << operator makes this a compile time check instead of a run time crash.  I am not sure if wxString::printf, does the same.  I do know that Boost format allows printf like syntax with the same type safety and still giving you the translation benifits.  You can also add the << operator to your classes so you just do "cout << MyClassInstance;".

GCC checks for this at compile time.

And how do you solve translation?

Can you show me please?

--- Code: (cpp) ---#include <stdio.h>

int main()
{
  printf("%s %d %g", 1, 2);
  return 0;
}
