Comparing two elements in different arrays of structs?

[spacecow]

I have two files, `cars.txt` and `reservation.txt`, both of the files have `resID` in common.

I want the user to enter a date, use that date to see the cars that are **unavailable**, then print them (through `resID`).

car.txt:
(From left to right: `reservationID`, `carID`, `carYOM`, `carMake`, `carModel`, `carFuel`, `catagory`.)

    R001;V001;2003;Toyota;Camry;Petrol;Budget
    R002;V002;2005;Toyota;Prius;Petrol;Economy
    R003;V003;1999;Ford;Falcon;Petrol;Midsize
    R004;V004;2007;Ford;Territory;Diesel;Fullsize
    R005;V005;2010;Ferrari;599;Petrol;Fullsize
    R006;V006;1998;Holden;Comadore;Diesel;Midsize
    R007;V007;2008;Honda;Civic;Petrol;Budget
    R008;V008;2000;Mazda;MX5;Petrol;Economy

reservation.txt:
(From left to right: `reservationID`, `customerID`, `reservationStartDate`, `reservationStartTime`, `reservationEndDate`, `reservationEndTime`.)

The code in question:

    #include <stdio.h>
    #include <string.h>
    #define MAX_CAR 100
    #define MAX_RES 100
    
    int main(){
        
        typedef struct{					//car struct
        	char reservationID[20];
        	char carID[20];
        	char carYOM[20];
        	char carMake[20];
        	char carModel[50];
        	char carFuel[20];
        	char catagory[20];
        } car_t;
        
        typedef struct{					//res struct
        	char reservationID[20];

        } res_t;
        
        car_t car[MAX_CAR];				//car array
        res_t reservation[MAX_RES];		//res array
        FILE *carHandle;
        FILE *resHandle;
        char line[100];
        char *item;
        int rescount = 0;
        int carcount =0;
        int k;
        int i;
        int option;
        char choice[20];    
        
        resHandle = fopen("reservation.txt","r");    
        
        while (fgets(line, 99, resHandle)){
          //cut up the reservation file line by line and put the bits into the res array.
            item = strtok(line,";");
            strcpy(reservation[rescount].reservationID,item);
            item = strtok(NULL,";");
            strcpy(reservation[rescount].customerID,item);
            item = strtok(NULL,";");
            strcpy(reservation[rescount].reservationStartDate,item);
            item = strtok(NULL,";");
            strcpy(reservation[rescount].reservationStartTime,item);
            item = strtok(NULL,";");
            strcpy(reservation[rescount].reservationEndDate,item);
            item = strtok(NULL,"\n");
            strcpy(reservation[rescount].reservationEndTime,item);
            rescount++;
        }
        
        fclose(resHandle);
        
        carHandle = fopen("car.txt","r");    
        
        while (fgets(line, 99, carHandle)){
            //cut up the car file line by line and put the bits into the car array.
            item = strtok(line,";");
            strcpy(car[carcount].reservationID,item);
            item = strtok(NULL,";");
            strcpy(car[carcount].carID,item);
            item = strtok(NULL,";");
            strcpy(car[carcount].carYOM,item);
            item = strtok(NULL,";");
            strcpy(car[carcount].carMake,item);
            item = strtok(NULL,";");
            strcpy(car[carcount].carModel,item);
            item = strtok(NULL,";");
            strcpy(car[carcount].carFuel,item);
            item = strtok(NULL,"\n");
            strcpy(car[carcount].catagory,item);
            carcount++;
        }
        
        fclose(carHandle);
        
        printf("Enter todays date (in YYYY/MM/DD format):");
        scanf("%s", choice);
        for (k=0;k<=rescount; k++){
        	if (strcmp(choice,reservation[k].reservationStartDate)>=0 && strcmp(choice,reservation[k].reservationStartDate)>=0){
        		for (i=0;i<=carcount; i++){
        			if (strcmp(car[i].reservationID,reservation[i].reservationID)==0){
        				printf("\nreservationID: %s\nreservationStartTime: %s\ncustomerID: %s\ncarid: %s\nyom: %s\nmake: %s\nmodel: %s\nfueltype: %s\ncategory: %s\n\n", car[k].reservationID, reservation[i].reservationStartTime, reservation[i].customerID, car[k].carID, car[k].carYOM, car[k].carMake, car[k].carModel, car[k].carFuel, car[k].catagory);
        				goto outofloop;
        			}
        		}
        	}else printf("\nall the cars are available\n");
        	break;
        }
        outofloop:
    
    	return(0);
    }

Currently the code only works with input strings '2012/02/12' to '2012/03/15' (i.e the first line of the reservation file)

Any other input string will not get past the first if statement.

Any help would be very appreciated!
