Question:
I am looking for a generic way to convert an intto a string. It cannot be platform- or compiler-specific in its implementation.
Answer:
The standard C++ library defines the classes std::istringstream andstd::ostringstream that can be used for manipulations on strings to accommodatevarious datatypes. The way to convert an integer to a string would be, for example:
std::string convertToString(int i){ ostringstream o; o << i; return o.str (); // returns std::string}Many compilers do not implement this version of the stream classesyet; if your compiler vendor does not, you can usethe older version, called strstream, in the exact same way.If all else fails you can always use the standard C library call sprintf todo the conversion. Here’s how:
void foo (){ char buf [10]; sprintf (buf,”%d”,10); puts(buf); // will print 10..}
