Hello everybody,
      I am develloping  a Graphical User Interface in X-Windows using C++.
I have to finish my program by the beginning of august. I have the following
problem :
      If we have a float variable ie a which holds the value lets say 12.34
how can i create a char pointer which will point to the string "12.34" ?
It would be extremely important for me if i could get an answer as soon as
possible.

Thanks very much in advance.

Hello everybody,

      I have the following problem:
I have a float variable:
float a=12.34;
and i would like to ask if it's possible to create a char pointer b
which will point to the float number as a string,in other words could i
have a pointer whichh will point to the string: "12.34"?
It's extremely important to me to get an answer as soon as possible.
thank you very much in advance

If you can't even manage this I don't fancy your chances of finishing by the
beginning of August - you've onlt got 4 days to go ... ;-)

Well :
#include <iostream.h>
#include <strstream.h>

main()
{
  float a = 12.34;
  char *toto;
  ostrstream TheStr;

  TheStr << a;

  toto = TheStr.str();

  cout << toto;
  return 0;
}

That's all I have to say.
