priority_queue::size (STL/CLR)
計數項目的數目。
size_type size();
成員函式會傳回受控制序列的長度。 您可以用它來判斷目前在受控制序列的項目數目。 如果您很在意是否該序列擁有非零值的大小,請參閱priority_queue::empty (STL/CLR)()。
// cliext_priority_queue_size.cpp
// compile with: /clr
#include <cliext/queue>
typedef cliext::priority_queue<wchar_t> Mypriority_queue;
int main()
{
Mypriority_queue c1;
c1.push(L'a');
c1.push(L'b');
c1.push(L'c');
// display initial contents " a b c"
for each (wchar_t elem in c1.get_container())
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
System::Console::WriteLine("size() = {0} starting with 3", c1.size());
// pop an item and reinspect
c1.pop();
System::Console::WriteLine("size() = {0} after popping", c1.size());
// add two elements and reinspect
c1.push(L'a');
c1.push(L'b');
System::Console::WriteLine("size() = {0} after adding 2", c1.size());
return (0);
