How to test whether stringstream operator>> has parsed a bad type and skip it

Question

Answer 1

If you like concision - here's another option that (ab?)uses && to get cout done only when a number's been parsed successfully, and when a number isn't parsed it uses the comma operator to be able to clear() stream error state inside the conditional before reading a character to be ignored...

#include 
#include 
#include 

int main()
{
    std::istringstream iss("2.832 1.3067 nana1.678 x-1E2 xxx.05 meh.ugh");
    double num = 0;
    char ignored;
    while (iss >> num && std::cout << num << '\n' ||
           (iss.clear(), iss) >> ignored)
        ;
}
