File Processing using structure and functions
Help! I am totally stuck. I need to open a file, then bubble sort it according to manufacturer. Plus I think my program is all screwed up form the functions on down. I must use this setup or I fail the program. Any help with the functions and the sort and search would be great. I have to sort by manufacturer and M.S.R.P. and also do a linear search for them. Thanks!
Code:
#include <stdio.h>

void printfFile(FILE *);

void searchManu(record);
