As stated, you know his key is of the form (in hex): 000000000000000000000000000000xx (for unknown xx).
What is the plaintext that Bob encrypted? Answer in ASCII or hex (but note the hex decodes to ASCII).

all component of array have same type, two different types doesn't use in single array

if array are store 10 quantities its index value varies from 0 to 9.

it stores 1st quantity value in index value 0 and this process will same till index value 9.

the answer is d. computer programmer
