#import<iostream>
int main(){char c;while(std::cin.get(c))std::cout<<c<<" ";}

Thanks to my father, who showed me a nifty trick for getting the characters directly from the input stream... and in turn almost halfed my byte count!

Old solution below using getline and joining substrings:

#import<iostream>
int i;int main(){std::string s,n;std::getline(std::cin,n);for(;i<n.size();i++){s+=n.substr(i,1)+" ";}std::cout<<s;}
