Hello, i've to submit this assigment in few hours and i'm very nervous,
it's sort of Gas Station managing programs, handeling input files, and printing results...
it's only 1 .c file and that's my first code lines, which defines the structs:
Code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
struct Gas_Station *pgasStationHead = NULL;
typedef struct Gas_Station {
char *name;
double octan95SS;
double octan95FS;
double octan98SS;
double octan98FS;
double gasSoldTotal;
double gasSoldSS;
double gasSoldFS;
struct Gas_Station* pgasStationNext;
struct Client_List* pclientHead;
} Station;
typedef struct Client_List {
char carID[10];
char gasType[3];
double gasAmount;
char serviceType[12];
struct Client_List* pclientNext;
} Client;
and those are the problematic functions and the main :
Code:
void CommandsSwitch(char *orders) {
FILE *input , *output;
input = fopen(orders, "rt");
output = fopen("result.txt" , "wt");
if (input == NULL) {
error("can't open file, might not exists");
}
else if (output == NULL) {
error("can't open file");
}
else {
do {
int i;
char *ptemp, *pfuncNum, *pcarID , *pstationName;
ptemp = fgets(ptemp , 80 , input);
if (ptemp[0] != '#') {
pfuncNum = strtok(ptemp , ",");
i = (int)pfuncNum[0];
switch (i)
{
case 1:
HowMuchGasPerStation(output);
break;
case 2 :
pstationName = strtok(pstationName , ",");
AverageGasInSpecieficStation(output , pstationName);
break;
case 3 :
HowMuchGasInAllStations(output);
break;
case 4 :
HowMuchGasFSInAllStations(output);
break;
case 5 :
pcarID = strtok(ptemp , ",");
HowMuchGasSoldByCarID(output , pcarID);
break;
case 6 :
pcarID = strtok(ptemp , ",");
pstationName = strtok(pstationName , ",");
HowMuchGasSoldByStationPerCarID(output , pcarID , pstationName);
break;
case 7 :
pcarID = strtok(ptemp , ",");
StationsWithClientByCarID(output , pcarID);
break;
case 8 :
pcarID = strtok(ptemp , ",");
pstationName = strtok(pstationName , ",");
HowMuchClientSpentByStation(output , pcarID , pstationName);
break;
case 9 :
pcarID = strtok(ptemp , ",");
HowMuchClientSpentInTotalByCarID(output , pcarID);
break;
case 10 :
pstationName = strtok(pstationName , ",");
ClientDetailsBySpecieficStation(output , pstationName);
break;
}
}
}while(!feof(input));
}
fclose(input);
fclose(output);
}
static void error(char *msg) {
fprintf(stderr , "Error: %s\n", msg);
exit(1);
}
int main (int argc, char* argv[]) {
int i;
FILE *f;
char *orders = argv[1];
for (i = 2; i < argc; i++) {
f = fopen(argv[i] , "rt");
if (f == NULL) {
error("can't open file, might not exists");
}
else {
AddStation(f);
}
fclose(f);
}
CommandsSwitch(orders);
}
now the error points to the " static void error(char *msg) " function but before that it pointed to " void CommandsSwitch(char *orders) " , the CommandsSwitch give the same error.
plz try to help and guide me, i'm confused.
tnx.
