Stage 3: Sorting a binary data file [3 marks] In this stage you will sort files of binary data in a known format. This stage develops the following specific skills: Reading and writing binary data files. Opening and closing files. Working with pointers to structures. Memory allocation, dynamically sizing an array. Using system library routines (specifically, a system library sort routine) Writing code to compare structures with a lexical sort order. .Using a function pointer in C Resources filestruct-description.txt: Describes the members of the C data structure which correspond to fields in the records of the data file. . . filestruct-sort.txt: Specifies the sorting order. .input-*.bin: Sample binary input files. output-*.bin: Sample binary output files corresponding to the input files. The output files contain the same data as the input files, but the records are sorted Useful Unix commands You might find the following Unix system commands helpful. Ce od
