data storage

when data is stored in RAM in  a c program is it stored without enclosing data type tags? (i.e. as opposed to how it would be stored in a html or xml document )

like if I have 

struct human 
{
 int hand;
 int foot;
 int ear;
};
human Friends[3];

  in memory that will end up as 

hand, foot, ear, hand, foot, ear,hand, foot, ear rather then

 human, hand, foot, ear,human, hand, foot, ear etc.
