Convert String containing several numbers into integers

by

I assume you want to read an entire line, and parse that as input. So, first grab the line:

std::string input;
std::getline(std::cin, input);

Now put that in a stringstream:

std::stringstream stream(input);

and parse

while(1) {
   int n;
   stream >> n;
   if(!stream)
      break;
   std::cout << "Found integer: " << n << "\n";
}

Remember to include

#include <string>
#include <sstream>
