C++标准程式库.pdf

详细讲诉了C++中的标准库式 // stl/mmap1.cpp #include <iostream> #include <map> #include <string> using namespace std; int main() { // type of the collection typedef multimap<int,string> IntStringMMap; IntStringMMap coll; // container for int/string values // insert some elements in arbitrary order // - a value with key 1 gets inserted twice coll.insert(make_pair(5,"tagged")); coll.insert(make_pair(2,"a")); coll.insert(make_pair(1,"this")); coll.insert(make_pair(4,"of")); coll.insert(make_pair(6,"strings")); coll.insert(make_pair(1,"is")); coll.insert(make_pair(3,"multimap")); /* print all element values * - iterate over all elements * - element member second is the value */ IntStringMMap::iterator pos; for (pos = coll.begin(); pos != coll.end(); ++pos) { cout << pos->second << ' '; } cout << endl; }
