operator<= (<stack>)
測試,如果左側的堆疊物件小於或等於右邊的堆疊物件。
bool operator<=(
const stack <Type, Container>& _Left,
const stack <Type, Container>& _Right
);
參數
_Left
型別 stack物件。_Right
型別 stack物件。
傳回值
true ,如果左側的堆疊小於或等於堆疊在運算子的右邊,否則 false。
備註
堆疊物件之間的比較可能會依據其項目比較配對方式。小於或等於兩個堆疊物件之間的關聯性會在第一次對的比較不相等的項目。
範例
// stack_op_le.cpp
// compile with: /EHsc
#include <stack>
#include <iostream>
int main( )
{
using namespace std;
// Declares stacks with default deque base container
stack <int> s1, s2, s3;
s1.push( 5 );
s1.push( 10 );
s2.push( 1 );
s2.push( 2 );
s3.push( 5 );
s3.push( 10 );
if ( s1 <= s2 )
cout << "The stack s1 is less than or equal to "
<< "the stack s2." << endl;
else
cout << "The stack s1 is greater than "
<< "the stack s2." << endl;
if ( s1 <= s3 )
cout << "The stack s1 is less than or equal to "
<< "the stack s3." << endl;
else
cout << "The stack s1 is greater than "
<< "the stack s3." << endl;
}
