我在使用數組的東西時遇到了問題。我收到以下錯誤使用cstring數組有問題
In function ‘int main(int, const char**)’:
75: error: cannot convert ‘char*’ to ‘char (*)[81]’ for argument ‘1’ ion(char (*)[81], OneItem*, int&, int&)’
In function ‘void parseInformation(char (*)[81], OneItem*, int&, in
164: error: ISO C++ forbids comparison between pointer and integer
166: error: incompatible types in assignment of ‘const char [2]’ to
169: error: ISO C++ forbids comparison between pointer and integer
174: error: ISO C++ forbids comparison between pointer and integer
174: error: ISO C++ forbids comparison between pointer and integer
176: error: invalid conversion from ‘char*’ to ‘char’
代碼沒有與行號對齊。我嘗試了多種Google搜索方式,有些東西還沒有找到解決方案。
const int MAX_CHARACTERS = 80;
const int MAX_INVENTORY = 12;
typedef char OneLine[MAX_CHARACTERS + 1];
struct OneItem
{
char product[MAX_CHARACTERS + 1];
int quantity;
float unitPrice;
float totalPrice;
};
int main(const int argc, const char* argv[])
{
OneLine fileName;
ifstream inFile;
OneLine readLine;
OneItem inventory[MAX_INVENTORY];
int readLineIndex;
int structureCounter = 0;
int averageQuantity;
float averagePrice;
float averageTotalPrice;
displayIntroduction();
getFileName(argc, argv, fileName);
if (!inFile)
{
cout << "File not found: " << fileName << endl;
}
else
{
inFile.open(fileName);
while(!inFile.getline(readLine, MAX_CHARACTERS, '\n').eof())
{
if (structureCounter < MAX_INVENTORY)
{
parseInformation(readLine,inventory, readLineIndex, structureCounter);
}
}
void parseInformation(OneLine readLine[],OneItem inventory[], int & readLineIndex, int & structureCounter)
{
int tempIndex = 0;
int valueCounter = 0;
OneLine tempArray;
while(readLine[readLineIndex] != '\n')
{
tempArray = "\0";
while(readLine[readLineIndex] == ' ')
{
readLineIndex += 1;
}
while(readLine[readLineIndex] != ' ' && readLine[readLineIndex] != '\n')
{
tempArray[tempIndex] = readLine[readLineIndex];
tempIndex += 1;
readLineIndex += 1;
}
if(valueCounter == 0)
{
for(int i = 0; i <= strlen(tempArray); i++)
{
inventory[structureCounter].product[i] = tempArray[i];
}
valueCounter += 1;
}
else if(valueCounter == 1)
{
inventory[structureCounter].quantity = atoi(tempArray);
valueCounter += 1;
}
else
{
inventory[structureCounter].unitPrice = atof(tempArray);
structureCounter += 1;
}
}
return;
把錯誤信息進入了一個問題,純文本,而不是一個鏈接到稻毛。 – Barmar
「parseInformation」的第一個參數應該是一個「OneLine」數組,但「readLine」不是一個數組。 – Barmar
@Barmar現在不會使'fileName'不是一個cstring數組?它使用相同的typedef,但是當我使用'fileName'使用strncopy時,我沒有任何錯誤。 – AdversaryCSGO
