WebApr 1, 2024 · Since Bitwise Operators work on the bit level, we will convert the numbers into their binary form and then we will compare all the individual bits. Here x is 4 and y is 5, and say the size of int is 4 bytes (which you can check by sizeof(int) in c/c++). So, the binary representation of 4 would be: 00000000 00000000 00000000 00000100 WebBitwise and in C++ programming language is used as follows: &. Short description of bitwise and.
