I'd generally do things a bit differently. Right now, you have a (mildly
messy) if statement in the inner loop. Unless it's crucial that there
NOT be an extra space after the final string, I'd just add a space after
the end of each string, which would simplify the code considerably.
yes, you are right but someone mentioned it on the newsgroup, IIRC.
I didn't see it, but I may (easily) have missed a post...
#include <iostream>
#include <iterator>
#include <algorithm>
int main() {
std::copy(std::istream_iterator<std::string>(std::cin),
std::istream_iterator<std::string>(),
std::ostream_iterator<std::string>(std::cout, " "));
return 0;
}
this code runs but it prints everything as sson as i press "Enter". i
think the problem wants us to print the input only when EOF is
encountered.
Yes -- rather than storing the data, it simply processes data and
produces output immediately.
int main() {
std::ostringstream temp;
std::copy(std::istream_iterator<std::string>(std::cin),
std::istream_iterator<std::string>(),
std::ostream_iterator<std::string>(temp, " "));
std::string data = std::string(temp.str(),
0,
temp.str().length()-1);
std::cout << data;
return 0;
}
this gives error at line: "std::ostringstream temp;"
Try adding:
#include <sstream>
up toward the beginning of the file and see if it doesn't help.
