This is an unpacked structure, so even though the size of char is generally 8 bits, it will be padded up to 32 on a 32-bit architecture and 64 on a 64-bit one.
so the size of the structures would be:
64 on 32-bit
128 on 64-bit
so the size of the structures would be:
64 on 32-bit
128 on 64-bit

64-bit: 64 for pointer + 8 for char = 72 bits
The size of the car can very from system to system, the important part is that you can explain why you say a number.
