callback function as the name suggest is basically a
function which gets called at the run time. it is a
reference to the executable code or a part of executable
code which is passed as an argument to another function.
for e.g if we want to forcefully terminate a program but if
there is some essential data which will get lost if program
gets terminated instantly.in that case writing a callback is
always a good deal.
---before writing a callback function you must have
knowledge of function pointers.
