I am not sure what is wrong, my .bin comes out to gibberish and I think I did the chain incorrectly, but I could be wrong.
Code:#include <stdio.h>#include <stdlib.h> #include <string.h> #include <time.h> typedef struct flight_struct{ char flightNum[7]; char originAirport[5]; char destAirport [5]; int timestamp; struct flight_struct *next; } flightRec; int main(){ struct flight_struct *head; // unchanging first node. struct flight_struct *tail; //the conductor. FILE* binFile = fopen("acars.bin","r"); FILE* DataOut; struct flight_struct *p =(struct flight_struct*) malloc(sizeof(flight_struct)); //malloc the first struct fread(p,sizeof(flightRec),1,binFile); //read the file into it. head = p; //make head point to that struct tail = p; //make tail point to that struct // fclose(binFile); while (feof(binFile) ==0){ flight_struct *temp = (struct flight_struct*) malloc(sizeof(flight_struct)); //malloc a new struct fread(temp,sizeof(flight_struct),1,binFile); //read the next struct from acars.bin into the structure you malloc'ed temp -> next = NULL; // add that struct to your linked list using the next memeber of the struct tail -> next = temp; // set tail to point to the element you just added tail = tail -> next; } //while not eof on acars file tail = head; while(tail != 0 ){ int t; t = tail -> timestamp; time_t time = t; printf("%s, %s, %s, %s\n\n",tail -> flightNum,tail -> originAirport,tail -> destAirport,asctime(gmtime(&time))); tail = tail -> next; } //starting at head traverse the list printing the leemnts of each strucure }
