Programming Assignment 1: IP Address AnalyzerPurpose:
The main purpose of this programming assignment is to revise the
topics covered in the first
three weeks including fundamentals of C programming, conditional
statements and
repetitive statements.
Description:
In this project you will analyse the structure of an IP address
(IPv4). You will need to use bitwise
operations and practice different numbering systems. You will
write a C program that
accepts an IP address, as well as subnet-mask in in decimal
format (base 10). The program
will convert the IP address as well as the subnet mask to
binary. The program will have options
to show the class of the address and to calculate the number of
available host addresses.
Programming Requirements
a. When you enter to the program your program will first prompt
for the IP address and thesubnet mask as follows:
Please enter the IP Address:
192.10.10.2
Please enter the Subnet Mask:
255.255.255.192
b. Then your program needs to display a menu to the user for
asking about the analysis tobe performed. Please note that the
program will keep on prompting the menu unless option
6 is chosen.
1. Convert IP address to binary2. Convert subnet mask to
binary3. Specify the class of the IP address4. Specify the number
of host addresses available5. Provide new IP Address and subnet
mask6. Exit
c. In case the user choses option 1, the IP address will be
converted to binary by convertingeach octet individually. You are
not allowed to use data structures such as arrays to store
values for the conversion operation. For the given example your
program will work as follows:
Binary representation of IP Address:
11000000.00001010.00001010.00000010
d. In case the user choses option 2, the subnet mask will be
converted to binary byconverting each octet individually. You are
not allowed to use data structures such as arrays
to store values for the conversion operation.For the given
example your program will work as
follows:
Binary representation of Subnet Mask:
11111111.11111111.11111111.11000000
e. In case the user choses option 3, the binary format of the IP
address will be used to specifythe class of the address using the
following table.
