What should I use instead of sscanf?

Question

I have a problem that sscanf solves (extracting things from a string). I don't like sscanf though since it's not type-safe and is old and horrible. I want to be clever and use some more modern parts of the C++ standard library. What should I use instead?

Answer 1

Try std::stringstream:

#include <sstream>  ...  std::stringstream s("123 456 789"); int a, b, c; s >> a >> b >> c; 

Answer 2

For most jobs standard streams do the job perfectly,

std::string data = "AraK 22 4.0"; std::stringstream convertor(data); std::string name; int age; double gpa;  convertor >> name >> age >> gpa;  if(convertor.fail() == true) {     // if the data string is not well-formatted do what ever you want here } 

If you need more powerful tools for more complex parsing, then you could consider Regex or even Spirit from Boost.
