Answer / vikraman85
In the first its simply structure,by declaring structure
variable accessors we can access those elements inside the
structure..
eg.struct x1 a,b,c;
In the next one the x2 acts as a datatype..
b'coz of the typedef function..
we can use x2 as datatype for the further calculations like
int,float which are predefined datatypes,but this is
manually defined datatype..
