Let’s go through a few examples using C’s sizeof operator. First, we’ll cover the unsurprising behaviors of arrays. In this example, we allocate the the array and reference it by the name under which it was declared. C voiddirect_reference(){uint8_t example_array[10];printf("%lu\...

Here, the size of the Complex struct is 12 bytes. The char takes 1 byte, the short takes 2 bytes, and the int takes 4 bytes. However, padding is added to align the int and short properly in memory. The layout in memory would look like this: 1 byte for c 3 bytes of padding 4 ...
