As we can see, age is an integer data type with a value of 34 hat was saved as hex value 22 00 00 00 since it is a 32 bit value stored in little endian format. Reading it as hex value 00000022 will give us 32 decimal. The string values for the first and last name are structures with default of 15 character array storage ( 0f000000 ) and a value that stores the current size of the used characters as an integer right before the size value. The floating point and boolean values are stored next. Unused available bytes are filled with a so called "garbage value", in this case, cc. There are 4 bytes before the string values that current state of this paper did not explore further at this time.
