Bits field
WebIn C language structure and union support a very important feature that is the bit field. The bit field allows the packing of data in a structure or union and prevents the wastage of memory. Note: The layout of the bit-fields is implementation-defined that is the reason a lot of people are avoiding the use of bit-filed. Web4. Bitwise AND your integer with the mask having exactly those bits set that you want to extract. Then shift the result right to reposition the extracted bits if desired. unsigned int lowest_17_bits = myuint32 & 0x1FFFF; unsigned int highest_17_bits = (myuint32 & (0x1FFFF << (32 - 17))) >> (32 - 17);
