Question

Suppose we number the bytes in a w-bit word from 0 (least significant)
to w/8 −1 (most significant).
Write code for the following C function, which will return an unsigned
value in which byte i of argument x has been replaced by byte b:
unsigned replace byte (unsigned x, int i, unsigned char b);
Examples:
replace byte(0x12345678, 2, 0xAB) → 0x12AB5678
replace byte(0x12345678, 0, 0xAB) → 0x123456AB

(4) [8] Suppose we number the bytes in a w-bit word from 0 (least significant)
to w/8 – 1 (most significant).
Write code for the following C function, which will return an unsigned
value in which byte i of argument x has been replaced by byte b:
unsigned replace_byte (unsigned x, int i, unsigned char b);
Examples:
replace_byte(0x12345678, 2, OXAB) → 0×12AB5678
replace_byte (Ох12345678, 0, ОХАВ) Ох123456AВ
