Question

How can I transfer uint64_t value to std::string?
I need to construct the std::string containing this value
For example something like this:

void genString(uint64_t val)
{
      std::string str;
      //.....some code for str 
      str+=(unsigned int)val;//????
}

Thank you

use either boost::lexical_cast or std::ostringstream

e.g.:

str += boost::lexical_cast<std::string>(val);

or

std::ostringstream o;
o << val;
str += o.str();
