How to parse comma delimited integers from a string in c++

Question

I have a function recieving a string, which is a pair of comma delimited integers in a fashion such as \"12,4\". How can I parse the integers out of this string?

Answer 1

Depends whether or not you can depend on the incoming data being valid. If you can, I'd do:

#include 
#include 
#include 

std::pair split(std::string const& str)
{
    int const a = std::atoi(str.c_str());
    int const b = std::atoi(str.c_str() + str.find(',') + 1);
    return std::make_pair(a, b);
}
