功能描述：
对list容器的大小进行操作 #include <iostream> #include <list> using namespace std; void printList(const list<int>& l) { for (list<int>::const_iterator it = l.begin(); it != l.end(); ++it) { cout << *it << " "; } cout << endl; } void test01() { list<int>l1; l1.push_back(10); l1.push_back(20); l1.push_back(30); l1.push_back(40); if (l1.empty()) { cout << "l1为空" << endl; } else { cout << "l1不为空" << endl; cout << "l1的大小为： " << l1.size() << endl; } l1.resize(10); printList(l1); l1.resize(2); printList(l1); } int main() { test01(); return 0; }
