C++ bitset reset()用法及代碼示例

bitset::reset()是C++ STL中的內置函數，用於重置參數中給定索引處的位。如果未傳遞任何參數，則所有位都將重置為零。

用法:

reset(int index)

參數：該函數接受參數索引，該索引指示必須將位重置為零的位置。如果未傳遞任何參數，則位集中的所有位都將重置為零。

返回值：該函數不返回任何內容。

下麵的程序演示了bitset::reset()函數。

示例1:

// CPP program to illustrate the 
// bitset::reset() function 
#include <bits/stdc++.h> 
using namespace std; 
  
int main() 
{ 
    // Initialization of bitset 
    bitset<4> b1(string("1100")); 
    bitset<6> b2(string("111111")); 
  
    // Function that resets all bits 
    cout << "Before applying reset() function: "
         << b1 << endl; 
  
    b1.reset(); 
    cout << "After applying reset() function: "
         << b1 << endl; 
  
    // Function that resets all bits 
    cout << "Before applying reset() function: "
         << b2 << endl; 
  
    b2.reset(); 
    cout << "After applying reset() function: "
         << b2 << endl; 
  
    return 0; 
}

輸出：

Before applying reset() function: 1100
After applying reset() function: 0000
Before applying reset() function: 111111
After applying reset() function: 000000

示例2:

// CPP program to illustrate the 
// bitset::reset() function 
#include <bits/stdc++.h> 
using namespace std; 
  
int main() 
{ 
    // Initialization of bitset 
    bitset<4> b1(string("1101")); 
    bitset<6> b2(string("111111")); 
  
    // Function that resets all bits 
    cout << "Before applying reset() function: "
         << b1 << endl; 
    b1.reset(2); 
    cout << "After applying reset(2) function: "
         << b1 << endl; 
  
    // Function that resets all bits 
    cout << "Before applying reset() function: "
         << b2 << endl; 
  
    b2.reset(3); 
    b2.reset(5); 
    cout << "After applying reset(3) and reset(5) function: "
         << b2 << endl; 
  
    return 0; 
}

輸出：

Before applying reset() function: 1101
After applying reset(2) function: 1001
Before applying reset() function: 111111
After applying reset(3) and reset(5) function: 010111
