Quick C++ Word Count Trick

Filed under: c — rcjp @ 2:19 pm

Probably not really useful in actual code but

#include <iostream>
#include <iterator>
#include <string>

typedef std::istream_iterator<std::string> in;

int main()
{
    std::cout << std::distance(in(std::cin), in());
}


will print the number of words piped in.
