deque::clear (STL/CLR)
移除所有項目。
void clear();
備註
成員函式有效地呼叫 deque::erase (STL/CLR)( deque::begin (STL/CLR)(), deque::end (STL/CLR)())。 您會用它來確保受控制序列是空的。
範例
// cliext_deque_clear.cpp
// compile with: /clr
#include <cliext/deque>
int main()
{
cliext::deque<wchar_t> c1;
c1.push_back(L'a');
c1.push_back(L'b');
c1.push_back(L'c');
// display initial contents " a b c"
for each (wchar_t elem in c1)
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
// clear the container and reinspect
c1.clear();
System::Console::WriteLine("size() = {0}", c1.size());
// add elements and clear again
c1.push_back(L'a');
c1.push_back(L'b');
for each (wchar_t elem in c1)
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
c1.clear();
System::Console::WriteLine("size() = {0}", c1.size());
return (0);
}
