[問題] run-time input string as file name
開發平台(Platform): (Ex: VC++, GCC, Linux, ...)
Dev-C++
問題(Question)：
開啟程式之後輸入檔名
開啟該檔案
餵入的資料(Input)：
filename.csv
預期的正確結果(Expected Output)：
看到filename.csv
錯誤結果(Wrong Output)：
無法開啟該檔案
file open error // 自訂的 error message
程式碼(Code)：(請善用置底文網頁, 記得排版)
#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
using namespace std;
int main()
{
string inputName;
cout << "input fileName with extension\n? ";
cin >> inputName;
fstream ioFile( inputName.c_str(), ios::in | ios::out );
if( !ioFile )
{
cerr << "file open error" << endl;
system("pause");
exit(1);
}
system("pause");
return 0;
}
inputName.c_str() 是爬文時看到的
但好像沒有用...
