bool (lowercase, built-in type) has an unspecified size, but is typically 1 byte. When in doubt, use sizeof( <type> ) to determine the byte count of any data type.

There are 8 bytes in a double
sizeof (long) and sizeof (short) often 4 or 8 for long, and 2 for short
16 bit and 32 bit are the most common values. See sizeof.
When you dereference a pointer you "read" the number of bytes determined by the pointer's type. That is, a char pointer dereferences a single byte while an int pointer dereferences 4 bytes (assuming a 32-bit int) -- regardless of the type actually stored at that address. However, note that a pointer can only actually point at a single byte since it only has storage for a single memory address. How many additional bytes are dereferenced is entirely dependant on the type of the pointer. To determine how many bytes are actually allocated to an address, use the sizeof operator, passing a dereferenced pointer (the pointer must point at the start of the allocation). If the pointer points at several elements of the same type (an array), then divide the total bytes by the size of the pointer's type to determine the number of elements in the array.
The total number of bytes allocated to the union will be the same number as would have been allocated if instead of the union was declared the largest member of the union. For example, if you declared: union myUnion { char c; int i; double d; } u;, then the space allocated to u will be the size of a double.

The padding needs to make the size of the data section 46 bytes. If the data received from the upper layer is 42 bytes, we need 46 − 42 = 4 bytes of padding.

A stick of 512 megabytes of RAM can hold about 512 megabytes of data. It cannot, however, store it for long because it is volatile and is not designed to store data.
