deque::clear (STL/CLR)

移除所有項目。

    void clear();

備註

The member function effectively calls deque::erase (STL/CLR)( deque::begin (STL/CLR)(), deque::end (STL/CLR)()).您可以用它來確定受控制的序列是空白。

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); 
    }
