我沒有編譯錯誤,但它崩潰上運行時, 這是我的相關代碼,首先它的結構:C指針,我做錯了什麼?
#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;
,之後有問題的區域:
void CommandsSwitch(FILE *input , FILE *output) {
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);
}
int main (int argc, char* argv[]) {
int i;
FILE *f , *input , *output;
for (i = 2; i < argc; i++) {

if (f == NULL) {
error("can't open file, might not exists");
}
else {
AddStation(f);
fclose(f);
}
}
if (argv[1] != NULL) {

if (input == NULL) {
error("can't open file, might not exists");
}
}
output = fopen("result.txt" , "w");
if (output == NULL) {
error("can't open file");
}
CommandsSwitch(input , output);
return 0;
}`
在CommandSwitch
函數調用堆棧指向* ptemp,說我不能使用它,因爲它沒有初始化或什麼... 我做錯了什麼?
請格式化你的問題,我無法理解的事情,因此,不能盡力幫助你。 – Juan 2010-11-15 21:40:31
有人可以編輯帖子嗎?謝謝。 – 2010-11-15 21:41:48
你將首先需要一個調試器 - 查明它在哪裏崩潰。 – 2010-11-15 21:42:11
