WebApr 6, 2024 · Conclusion: In summary, a custom assignment operator in C++ can be useful in cases where the default operator is insufficient or when resource management, memory allocation, or inheritance requires special attention. It can help avoid issues such as memory leaks, shallow copies, or undesired behaviour due to differences in object states. WebAug 13, 2024 · 1. A bitset stores bits (elements with only two possible values: 0 or 1). We can however get the part of a string by providing positions to bitset constructor (Positions are with respect to string position from left to right) 2. We can construct a bitset using the characters in the std::basic_string _str. WebALX23z • 2 yr. ago. Bitset usually uses some underlying default integer for containing data. So in your case bitset<1>, bitset<32>, bitset<64> will be of the same size. Using such an integer is definitely more efficient for larger bitset sizes - for variety of reasons - but I cannot say much for size of 8. flannery lisa moore summary
