C++ examples for STL:list
Demonstrate reverse(), merge(), and unique() on list
#include <iostream> #include <list> using namespace std; int main()/*from w ww .java 2 s . c o m*/ { int j; list<int> list1, list2; int arr1[] = { 40, 30, 20, 10 }; int arr2[] = { 15, 20, 25, 30, 35 }; for(j=0; j<4; j++) list1.push_back( arr1[j] ); // list1: 40, 30, 20, 10 for(j=0; j<5; j++) list2.push_back( arr2[j] ); // list2: 15, 20, 25, 30, 35 list1.reverse(); // reverse list1: 10 20 30 40 list1.merge(list2); // merge list2 into list1 list1.unique(); // remove duplicate 20 and 30 int size = list1.size(); while( !list1.empty() ) { cout << list1.front() << ' '; // read item from front list1.pop_front(); // pop item off front } cout << endl; return 0; }
