Re: [Dev-C++] Integer to std::string?

[Michael C. <jd...@ho...>]

Hi,

Try

---
#include <stdlib.h>
#include <iostream.h>
#include <string>

int main ()
{
  int myInt = 5;

  string str (ltoa(myInt));
  cout << str << endl;

  return 0;
}
---

NOTE: I did not write this on DevC++ but on HPUX 10.20.

Re: [Dev-C++] Integer to std::string?

Hi,

Sorry, ltoa is not part of the POSIX standard (but I have got an old book!), 
it is a vendor specific extension.

You would have to use one of the c string library functions as suggested to 
you by someone before.

You may want to look at the cout functions for precision as well.
