Answer / poornakala
you ca implement stack with union datatype... u may think
of structures.. but struct use storin of all values and mem
allocated for all in each.. but in union only one at a
time... this is right i think...

Answer / krishan
We can use a struct containing "void * " in it and an
unsigned int to store the datatype which "void *" will store
(can be set at time of storing the value). To store a value
of any type we can dynamically allocate the space and set
the unsigned int to some pre-determined constants. Like
1 for int type.
2 for char.
3 for char string.
4 for any other type. say some user datatype.

Answer / sudipto ghosh
yes it is possible to insert different types of element in a
stack.
insted of defining the member as int or float or so on. we
will define each element as a union which will be consisting
of all types of data type and only one can be used at a
time. in order to determine which type of element is being
pushed or poped we will define a flag with in union which
keeps the track of data type being used.
