我發現我在整個程序中反覆使用相同的代碼。爲了提高工作效率等,我決定啓用一個文件處理類,它允許我與所有文件進行交互。C++文件處理類
在創建這個 - 我得到奇怪的錯誤,我不能解碼。例如:
Error 11 error LNK1169: one or more multiply defined symbols found C:\Users\JG\Desktop\ProjectWork\ConsoleApplication1\Debug\ConsoleApplication1.exe 1 1 ConsoleApplication1
和
Error 8 error LNK2005: "bool __cdecl bolFileExist(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >)" ([email protected]@[email protected][email protected]@[email protected]@[email protected]@[email protected]@[email protected]@@Z) already defined in Draw.obj C:\Users\JG\Desktop\ProjectWork\ConsoleApplication1\ConsoleApplication1\Player.obj ConsoleApplication1
我只能把這個下來的代碼在Filez.h
文件註釋所有它建立並運行良好的相關代碼。我已經對此做了一些重新研究,並且悲傷地畫了一個空白。
我非常感謝這段代碼的一些反饋 - 以及一些關於我做錯了什麼的指針。
string getFinalLineOfFile(string FileLoction)
{
//http://bit.ly/1j6h6It
string line = " ";
string subLine;
ifstream readFile(FileLoction);
string found_DrawID; //Username in the file;
while (getline(readFile,line)) {
stringstream iss(line);
//We are only Interested in the First Value
iss >> subLine;
}
//The Value at CurrentDrawID will be the final value in the file;
return subLine;
}
bool bolFileExist(string FileLocation)
{
//If that Exists. Return it.
ifstream readFile(FileLocation);
return readFile;
}
bool itemExistLineOne(int find, string FileLocation)
{
string line = " ";
//ifstream readFile(".//Draws//Draws.txt");
ifstream readFile(FileLocation);
string foundID; //Username in the file;
while (getline(readFile,line)) {
stringstream iss(line);
iss >> foundID;
//Covert the Integer input to a String for comparison.
if (to_string(find) == foundID) {
return true;
}
}
return false;
}
void CreateNewFileLine(string Location, string text){
ofstream output_file(Location, ios::app);
if (!output_file.is_open()) { // check for successful opening
cout << "Output file could not be opened! Terminating!" << endl;
}
else{
output_file << text;
output_file << endl; //Create new line at the end of the file.
output_file.close();
}
}
非常感謝,
確保這些功能定義在一個CPP文件不在標題中。 – drescherjm
