Using C$++,$Write a program to ask user to enter $20$ bytes of Hexadecimal number. $-$ Your program should run multiple time.

$-$ Your program should have error checking for non$-$hexadecimal number, illegal version, and illegal header size. Extract the input and display the following information in decimal:

$1.$ Version

$2.$ Header Length $($how many bytes$)$

$3.$ Total Length $($how many bytes$)$

$4.$ The size of Data $($how many bytes$)$

$5.$ Protocol

$6.$ Source IP address

$7.$ Destination IP address

For Example: An IP datagram has arrived with the following information in the header $($in hexadecimal$)$:

$4500005400030000200600007$C$4$E$0302$B$40$E$0$F$02$

The answer should be

Version: $4$

Header Length: $20$

Total Length: $84$

The size of Data: $64$

Protocol: $6$

Source IP address: $124\mathrm{.}78\mathrm{.}3\mathrm{.}2(7$C $4$E $0302)$

Destination IP address: $180\mathrm{.}14\mathrm{.}15\mathrm{.}2($B$40$E $0$F $02)$

$45$H$1005400030000200600007$C$4$E$0302$B$40$E$0$F$02$

The answer should be

Error: illegal digit for hexadecimal

$3500005400030000200600007$C$4$E$0302$B$40$E$0$F$02$

The answer should be

Error: Wrong version $($should be $4$ or $6)$

$4400005400030000200600007$C$4$E$0302$B$40$E$0$F$02$

The answer should be

Error: Illegal header size
