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.

A useful way to remember this is that the tilde is sometimes called a twiddle, and the bitwise complement twiddles every bit: if you have a 1, it's a 0, and if you have a 0, it's a 1. 0, of course, is all 0s: 00000000 00000000. flight fare from shj to trv
