Bitset flip c++

WebOct 21, 2024 · I found the the following example in the C++ Primer book: #include #include std::bitset<32> bitvec(1U); bitvec[0].flip(); // flip the value of the bit at position 0 ~bitvec[0]; // equivalent operation; flips the bit at position 0 The book claimed that the last two lines of codes are equivalent and why is that true? I thought ...WebUse the bitwise OR operator ( ) to set a bit. number = 1UL << n; That will set the n th bit of number. n should be zero, if you want to set the 1 st bit and so on upto n-1, if you want to set the n th bit. Use 1ULL if number is wider than unsigned long; promotion of 1UL << n doesn't happen until after evaluating 1UL << n where it's undefined ...
