Bit fields can't be used in union
WebBit-fields and unions may be combined in a way that permits programmers to pack and unpack bits in an integer. Unions allow programmers to circumvent C++'s strong typing rules while bit-fields allow programmers to access the … WebMay 5, 2024 · Setting the bits is done by multiplying the byte by two (left shift 1 bit is fastest way) which moves the saved current pin state (in bit 0) into the previous pin state position (bit 1) and the bit that was the previous state into bit 2 then masking off the high 6 bits (byte = byte & 3) to erase that bit and then adding the current pin state …

WebBit fields can be defined just like a normal member in a structure or union, except you will add a colon after the bit field variable name and then a bit field width. Here's an example of where we declared a structure with bit fields x, y and z, with respective bit sizes of three, two and one bits. WebBit fields CANNOT be used in union. True False Answer: Option Explanation: The following is the example program to explain "using bit fields inside an union".
