rt.exe应用程序错误

1 病毒引起的：升级杀毒软件或下载专杀工具，清理恶意插件，对电脑全盘杀毒(建议使用金山毒霸sp6)。

2硬件引起的：

（1）可能是内存条出现的小问题，关机断电，把内存条拆下清理干净重新安装。必要时更换内存条。

（2）有些硬件配置过低，尤其是运行大型游戏时，不能正常运行。必要时升级电脑显卡、内存条等硬件。（硬件上一般不会出现该问题）

3软件引起的：

（1）安装的软件与系统或其它软件发生冲突，盗版或带病毒的软件，请慎重下载软件，最好使用正版。【这里主要说的是检查开机启动项，把没必要启动的启动项禁止开机启动】

（2）如果你的电脑中安装了两款或两款以上的同类软件，比如:两款杀毒软件、两款优化系统软件等，请卸载一款，以免发生冲突，以保持电脑稳定性。

（3）有些系统补丁下载安装了错误补丁，可能与您当前的系统或其它软件发生冲突，也会出现该问题。卸载该补丁，找到适合您电脑补丁，重新下载重新安装。

r 读取， t 文本文件，+ 可更新文件内容

mode

C string containing a file access mode. It can be:

"r"    read: Open file for input operations. The file must exist.  

"w"    write: Create an empty file for output operations. If a file with the same name already exists, its contents are discarded and the file is treated as a new empty file.  

"a"    append: Open file for output at the end of a file. Output operations always write data at the end of the file, expanding it. Repositioning operations (fseek, fsetpos, rewind) are ignored. The file is created if it does not exist.  

"r+"    read/update: Open a file for update (both for input and output). The file must exist.  

"w+"    write/update: Create an empty file and open it for update (both for input and output). If a file with the same name already exists its contents are discarded and the file is treated as a new empty file.  

"a+"    append/update: Open a file for update (both for input and output) with all output operations writing data at the end of the file. Repositioning operations (fseek, fsetpos, rewind) affects the next input operations, but output operations move the position back to the end of file. The file is created if it does not exist.  

With the mode specifiers above the file is open as a text file. In order to open a file as a binary file, a "b"character has to be included in the mode string. This additional "b" character can either be appended at the end of the string (thus making the following compound modes: "rb", "wb", "ab", "r+b", "w+b", "a+b") or be inserted between the letter and the "+" sign for the mixed modes ("rb+", "wb+", "ab+").

The new C standard (C2011, which is not part of C++) adds a new standard subspecifier ("x"), that can be appended to any "w" specifier (to form "wx", "wbx", "w+x" or "w+bx"/"wb+x"). This subspecifier forces the function to fail if the file exists, instead of overwriting it.

If additional characters follow the sequence, the behavior depends on the library implementation: some implementations may ignore additional characters so that for example an additional "t" (sometimes used to explicitly state a text file) is accepted.

On some library implementations, opening or creating a text file with update mode may treat the stream instead as a binary file.

Text files are files containing sequences of lines of text. Depending on the environment where the application runs, some special character conversion may occur in input/output operations in text mode to adapt them to a system-specific text file format. Although on some environments no conversions occur and both text files and binary files are treated the same way, using the appropriate mode improves portability.

For files open for update (those which include a "+" sign), on which both input and output operations are allowed, the stream shall be flushed (fflush) or repositioned (fseek, fsetpos, rewind) before a reading operation that follows a writing operation. The stream shall be repositioned (fseek, fsetpos, rewind) before a writing operation that follows a reading operation (whenever that operation did not reach the end-of-file).
