我正在加載的文本文件位於下面代碼的註釋部分。我無法讓sscanf()
像我認爲應該那樣工作。必須有一種方式,幾乎是這個優雅而不必使用指針,通過每個角色中去,爲循環等解析C中的管道分隔線條
//Apex City Hotel|4|61 Grassmarket|Edinburgh|EH1

代碼:
int main(void)
{
char inputArray[NUM_OF_CHARACTERS];
FILE *fp = fopen("OpenChampionshipHotels.txt", "r");
fgets(inputArray, NUM_OF_CHARACTERS, fp);
if (fp == NULL)
{
printf("Error Reading File\n");
exit(1);
}
// copy lines from text file to array
char hotelName[lineCount][NUM_OF_CHARACTERS];
char hotelRating[lineCount][NUM_OF_CHARACTERS];
char hotelStreetAddress[lineCount][NUM_OF_CHARACTERS];
char hotelCity[lineCount][NUM_OF_CHARACTERS];
char hotelPostalCode[lineCount][NUM_OF_CHARACTERS];
lineCount = 0;
while(fgets(inputArray, sizeof(inputArray), fp) != NULL)
{
sscanf(inputArray, "%[^|]|%[^|]|%[^|]|%[^|]|%s",
hotelName[lineCount],
hotelRating[lineCount],
hotelStreetAddress[lineCount],
hotelCity[lineCount],
hotelPostalCode[lineCount]);
printf("%s\n", hotelName[lineCount]);
printf("%s\n", hotelRating[lineCount]);
printf("%s\n", hotelStreetAddress[lineCount]);
printf("%s\n", hotelCity[lineCount]);
printf("%s\n", hotelPostalCode[lineCount]);
lineCount++;
}
fclose(fp);
return 0;
}
*「我無法讓sscanf()像我認爲應該那樣工作。」*您認爲它應該如何工作?你得到了什麼結果?你有什麼試圖調試或解決問題? (詢問** 101 **的問題) – abelenky
'「錯誤讀取文件」是無用錯誤消息的典型示例。包括文件名和原因! 'man perror' –
請注意,您應該檢查'sscanf()'的返回值以確保該行的格式正確。如果您獲得完整的郵編(EH3 9JX),則需要修正'%s'轉換規範。 –
