Description

The C++ function std::bitset::reset() reset single bit of bitset to zero.

Declaration

Following is the declaration for std::bitset::reset() function form std::bitset header.

C++98

bitset& reset (size_t pos);

C++11

bitset& reset (size_t pos);

Parameters

pos − Position of the bit whose value is reset.

Return value

Returns this pointer.

Exceptions

Throws out_of_range exception if pos is greater than or equal to bitset size.

Example

The following example shows the usage of std::bitset::reset() function.

#include <iostream>
#include <bitset>

using namespace std;

int main(void) {

   bitset<4> b("1111");

   cout << "Before reset operation b = " << b << endl;

   b.reset(0);

   cout << "After reset operation b = " << b << endl;

   return 0;
}

Let us compile and run the above program, this will produce the following result −

Before reset operation b = 1111
After reset operation b = 1110
