移除第一個項目。

    void pop_front();

備註

成員函式會移除受控制序列必須為非空白的第一個項目。您可以用它來縮短 deque 中最前面的一個項目。

範例

// cliext_deque_pop_front.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 contents " a b c" 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// pop an element and redisplay 
    c1.pop_front(); 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
    return (0); 
    }
