Sir using size of operator in case of dynamic memory allocation is good practice ? Because size of is a compile time process so when i move the executable to another different machine will there be any issues

sir, is it compiler optimization? or memory padding? 4:15

The structure taking up 8 bytes is a requirement imposed by Microsoft. More specifically:
"The alignment of the beginning of a structure or a union is the maximum alignment of any individual member. Each member within the structure or union must be placed at its proper alignment... which may require implicit internal padding, depending on the previous member."
"Structure size must be an integral multiple of its alignment, which may require padding after the last member. Since structures and unions can be grouped in arrays, each array element of a structure or union must begin and end at the proper alignment previously determined."
