The answer for the first one is "return 0x07 & x". I just don't understand how to get there

4 Problem 4: 14 Points The following table defines seven bit fields within a 32 bit word. Each field has a name, bit indices that compose it and its length in bits Name Bits length vall 00 023 bits val2 03- 075 bits val3 08 -092 bits val4 10- 178 bits val5 18-247 bits val6 25 -25 1 bits val7 26-316 bits Where bit 00 corresponds to the least signficant bit and bit 31 to the most significant eg. The 32 bit word layout is [b31b30b29.. .bo2bo1 boo] Assuming the following two typedefs typedef int Word; typedef unsigned char Val; Complete the following functions that each take an int and extract the field corresponding to the function's name returning the field value as an unsigned char. Val vall (Word x) return Val val2 (Word x) return
