C++ examples for STL:vector
Compare two vector containers.
#include <iostream> #include <vector> using namespace std; void show(const char *msg, vector<char> vect); int main() {/*from w w w . j a v a 2 s. c om*/ // Declare an empty vector that can hold char objects. vector<char> v; // Declare an iterator to a vector<char>. vector<char>::iterator itr; // Obtain an iterator to the start of v. itr = v.begin(); // Declare a reverse iterator. vector<char>::reverse_iterator ritr; // Create another vector that is the same as the first. vector<char> v2(v); show("The contents of v2: ",v2); cout << "\n"; // Compare two containers. if(v == v2) cout << "v and v2 are equivalent.\n\n"; return 0; } // Display the contents of a vector<char> by using an iterator. void show(const char *msg, vector<char> vect) { vector<char>::iterator itr; cout << msg; for(itr=vect.begin(); itr != vect.end(); ++itr) cout << *itr << " "; cout << "\n"; }
