如何用c ++ win32写入文件？ （VS 2010）

Question

I'm using visual studio 2010 and I'm writing a c++ win32 application(not a console application). I need to know how to write to a file from this application. so far my application runs properly but when I tried to include iostream and fstream in my project the compiler gave me errors.

I need to know what libraries I should include so I can write to a file and I need to know what function I should use to do this task.

Another thing I need is how can I move from a character to another and from a line to another inside the file.

I am sorry for all the requests but I'm in desperate need to learn those things. Thank you...

Answer 1

You can use

1. C Libraries
   fopen , fputs , fwrite etc

2. C++ Libraries
   ofstream , fstream etc

3. You can use Windows APIs.
   CreateFile , WriteFile etc.

4. You can use POSIX like functions
   _open , _creat , _write etc.

Take a look at this example for how to work with file streams:

How to redirect cin and cout to files?

I'm not sure if by move through the file, you want a get version or a set version.

For getting:
Line : Use std::getline like in the example.
Character : Use file.get() to retrieve a single character.

For writing, just add std::endl to add a new line. You can alternatively use the escape character '\\n'
