WebFor scanf, you need to use %hu since you're passing a pointer to an unsigned short. For printf, it's impossible to pass an unsigned short due to default promotions (it will be promoted to int or unsigned int depending on whether int has at least as many value bits as unsigned short or not) so %d or %u is fine. 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);

WebFeb 13, 2011 · struct { unsigned short my_number : 16; }; In a typical case where short is 16 bits anyway, this won't impose any overhead -- and in the rare case that some extra code needs to be inserted to clamp the value to the right range, this handles that automatically.

Webbyte1 is a variable containing bit pattern 0xFF. If char is unsigned that value is interpreted as 255, if it is signed it is -128. When doing the calculation, C will extend the value to an int size (16 or 32 bits generally). This means that if the variable is unsigned and we will keep the value 255, the bit-pattern of that value as int will be ... WebJan 20, 2016 · As you can see, int-> short yields the lower 16 bits, as expected. Casting short to int yields the short with the 16 high bits set.
