Create sets with string elements
#include <set> #include <iostream> #include <string> using namespace std; template <class T> void print(T& c){ for( typename T::iterator i = c.begin(); i != c.end(); i++ ){ std::cout << *i << endl; } } int main() { set<string> first; first.insert("r"); first.insert("T"); first.insert("s"); }
