Integer and struct are value types in .net.Integer has 
fixed range of values hence they are going to be stored in 
the stack memory.so,what ever is stored in stack memeory is 
a value type.struct is similar to a class(1.e, it contains 
dataitems of different datatypes) but the only difference 
is that struct is a value type ,class is a reference 
type.struct is a value type because the values in struct 
can be accesed with the help variable created for the 
struct i.e,Dot operator appended to the struct variable can 
be used to access each of the individual data items in the 
struct class.
