Answers:
1. whenever a 'const' qualifier is added previously to a variable
declaration it means that the value of the variable is automatically
initialized to '0'(because of the 'auto' type of the const variable) and
cannot be changed in any of the following assignment statements to the const
variable.
2.
Here for the structure struct s1 since the entire structure is ending within
8 bytes no padding is done which means
s1: [char a]
1byte
but for the structure struct s2 consider the following:
s2: [ char a
1byte
------ int a-------
------4bytes----]
so here the concept of padding comes to make all the variable aligned in
even boundaries and so the structure after aligning will look as:
s2: [ ------ char b----
------4byte-----
------ int a-------
------4bytes----]
so the size of strcut s2 will be 8bytes..........
