Auto in C++
// C++ program to demonstrate that we can use auto to // save time when creating iterators #include <bits/stdc++.h> using namespace std; int main() { // Create a set of strings set<string> st; st.insert({ "geeks", "for", "geeks", "org" }); // 'it' evaluates to iterator to set of string // type automatically for (auto it = st.begin(); it != st.end(); it++) cout << *it << " "; return 0; };
