operator!= (<stack>)
测试,如果运算符左侧的对象堆与右侧的堆栈对象不等于。
bool operator!=(
const stack <Type, Container>& _Left,
const stack <Type, Container>& _Right,
);
参数
_Left
类型 stack对象。_Right
类型 stack对象。
返回值
true,则堆栈或堆栈不相等;false,则堆栈或堆栈是否相等。
备注
在堆栈对象之间的比较基于元素的一种比较成对。 两个堆栈相等,如果变量具有相同数量的元素,它们各自的元素具有相同的值。 否则为不相等。
示例
// stack_op_me.cpp
// compile with: /EHsc
#include <stack>
#include <vector>
#include <iostream>
int main( )
{
using namespace std;
// Declares stacks with vector base containers
stack <int, vector<int> > s1, s2, s3;
// The following would have cause an error because stacks with
// different base containers are not equality comparable
// stack <int, list<int> > s3;
s1.push( 1 );
s2.push( 2 );
s3.push( 1 );
if ( s1 != s2 )
cout << "The stacks s1 and s2 are not equal." << endl;
else
cout << "The stacks s1 and s2 are equal." << endl;
if ( s1 != s3 )
cout << "The stacks s1 and s3 are not equal." << endl;
else
cout << "The stacks s1 and s3 are equal." << endl;
}
