bitset::operator!=
方法會使用指定的bitset的不相等測試目標bitset。
bool operator !=(
const bitset<N>& _Right
) const;
參數
- _Right
要與不相等的目標bitset比較的bitset。
傳回值
true ,如果bitsets不同, false ,如果兩者相同。
備註
Bitsets必須是不要測試是否相等的相同大小是由成員運算子函式。
範例
// bitset_op_NE.cpp
// compile with: /EHsc
#include <bitset>
#include <iostream>
int main( )
{
using namespace std;
bitset<5> b1 ( 7 );
bitset<5> b2 ( 7 );
bitset<5> b3 ( 2 );
bitset<4> b4 ( 7 );
if ( b1 != b2 )
cout << "Bitset b1 is different from bitset b2." << endl;
else
cout << "Bitset b1 is the same as bitset b2." << endl;
if ( b1 != b3 )
cout << "Bitset b1 is different from bitset b3." << endl;
else
cout << "Bitset b1 is the same as bitset b3." << endl;
// This would cause an error because bitsets must have the
// same size to be tested
// if ( b1 != b4 )
// cout << "Bitset b1 is different from bitset b4." << endl;
// else
// cout << "Bitset b1 is the same as bitset b4." << endl;
}
