http://www.serc.iisc.ernet.in/ComputingFacilities/systems/cluster/xlf/html/xlfug/ug35.htm this says int is always 4 bytes and pointer is 8 bytes on 64 bit compiler.
so how does padding affect these structures because of the difference in size of int and pointer? I tried this program https://ideone.com/CRU6x#view_edit_box char always gets 4 bytes whenever it has int or double in the same struct irrrespctive of the order of the declaration of variables. I thought char should get size 8 when there is a double in the ame struct whereas it gets size 4 only. what is the problem here?
