SpletHere, swapBitsNumber method is used to swap two bits of a number. It takes the number, first position and second position of the bits as the parameters and returns the new number by swapping the bits. firstBit is the first bit of the number at firstPosition and secondBit is the second bit of the number at secondPosition. Splet01. feb. 2024 · It is not allowed to change the bytes pointed to. Making the array static saves you from zeroing the first byte repeatedly. BTW, it is sufficient to provide the first byte, as all other bytes are zeroed automatically. However, the last bytes will be updated on each transfer. sizeof is an operator, not a function.
