=====front===== Syntax: #include TYPE& front(); const TYPE& front() const; The front() function returns a reference to the first element of the vector, and runs in [[/complexity|constant time]]. For example, the following code uses a vector and the sort()_algorithm to display the first word (in alphabetical order) entered by a user: vector words; string str; while( cin >> str ) words.push_back(str); sort( words.begin(), words.end() ); cout << "In alphabetical order, the first word is '" << words.front() << "'." << endl; When provided with this input: now is the time for all good men to come to the aid of their country ...the above code displays: In alphabetical order, the first word is 'aid'.
