In C language...

Write a function named zBytes that takes one integer argument and returns the number of zero bytes in that integer. For the purposes of this exercise, assume that an integer is 32 bits. (So your function will return a number between 0 and 4.)

Examples:

3 has 3 zero bytes (0x00000003)

11259136 has 2 zero bytes (0x00abcd00)

-1 has 0 zero bytes (0xFFFFFFFF)
