This is not the right answer bro, I'm 100% sure the answer of Q10 is C not A

If the size of one integer was *always* 4 bytes, then the answer would be A) 400 bytes. The C11 standard (nor any C standard) does not specify sizeof(int) to always be 4. For what reasons might sizeof(int) *not* be 4?

Not OP but would it be because it depends on the bits (i.e. 32-bit or 64-bit) where 32-bit is 4 bytes per integer but something like 16-bit will give 2 bits so it'll be value of 200. That's why the answer is B. Because the value/byte of each object is dependent on the operating system and compiler ?
