无法打开文件n C ++ [英] Unable to open file n C++

问题描述

hi


我正在尝试用c ++编写/读取文件。写入文件的函数如下：

hi
I'm trying to write/read from a file in c++. The function which writes to a file is as follows:

const char * EncQR = Extract_ClientPublicKey_Encrypt_QRcode(str, ClientCert_String);

ofstream myfile1;
myfile1.open("ram.txt");
if (myfile1.is_open())
  {
	   myfile1 <<EncQR<<"\n";
  }
else
   cout<<"Unable to open file";

前面的代码工作正常，并写入txt文件。但问题在于下一个函数，它尝试从文件中读取：

The previous code works fine, and write into a txt file. But the problem is with the next function, which tries to read from a file:

int _tmain(int argc, _TCHAR* argv[])
{
   string line;
  // reading a text file
  ifstream myfile1("ram.txt");
  if (myfile1.is_open())
  {
   while(! myfile1.eof()) {
			getline(myfile1, line);
			std::cout << line << "\n\n";}
  }

  else cout << "Unable to open file";
  getch();
  myfile1.close();
  return 0;
}

我不断收到无法打开文件。我尝试过另一个由一行组成的文件，它正在运行。但是使用ram.txt文件，它由多行组成，它不起作用。

我甚至试图将文件复制到我的项目所在的目录中，而且，没有工作。



需要帮助pleeeeease



问候。

Where i keep getting "Unable to open file". I've tried another file consisting of a single line, and it was working. but with the "ram.txt" file, which consists of multiple lines, it doesn't work.
I even tried to copy the file into the directory in which my project is located, and still, didnt work.

Need help pleeeeease

Regards.

推荐答案

正在创建的文件在哪里？



您可以尝试：



打开（。\\ram.txt）
两个函数的


。我想你会觉得它有用。

Where is the file being created?

You might try:

open(".\\ram.txt")

for both functions. I think you'll find it works.
