Re: [Boost-users] [string] HowTo: equiv of printf("%.5s\n",myBuf10);

10 Apr 2006


      This seems to work ok using boost::format:

#include <iostream>
#include 
void main(void)
{
   std::string myBuf10("1234567890");
   std::cout << "Put truncated: "
          << boost::format("%|.5s|\n") % myBuf10
          << " part of " << myBuf10 << std::endl;
}

I've been puzzled about doing the equivalent of:
printf("%.5s\n", myBuf10);
and also:
printf("%.*s\n", 5, myBuf10);
Note: newbie with std::string ... using Microsoft vc7.1 compiler
Thanks.
string isn't a Boost library. You're unlikely to get any help here. Try
