Program structure and design: (Write a C Program to compile in linux) Create a structure type called:
struct address_t
with components for the four integers of an IPv4 address along with a fifth component in which to store an associated alias of up to 10 characters.
Read the file CS222_Inet. txt in order to count the number of records in the file. Provide error checking in order to ensure that each integer portion of the IP address falls within the range [0..255]. If a record contains an illegal IP address, that record is written to the file
222_Error_report and excluded from the 222_Locality_Report
Once the record count has been established, rewind() the file.
Dynamically allocate the proper amount of memory (using malloc()) to store a dynamically allocated array of address_t structures based on the record count.
Dynamically allocate the proper amount of memory (using malloc()) to store a dynamically allocated array of address_t structures based on the record count.
Reread the file and store the data within the dynamically allocated array of address_t structures. Once the array of structures has been populated,
close the CS222_Inet. txt file.
Conditions to write program:
For this exercise you may have a maximum of 2 global variables.
Include at least the following UDFs (You may define your own prototypes):
a) readDataFile
b) generateLocalityRpt
c) getDateAndTime
remember: Max 2 global variable
