How to disable the escape sequence in C++

Question

我用C ++来处理很多文件，我必须在源代码中写这样的文件名： "F:\\\\somepath\\\\subpath\\\\myfile" ，我想知道如果有什么方法可以摆脱键入“\\ \\“在字符串文字上下文中获取一个字符'\\'，即我希望我只能写出"F:\\somepath\\subpath\\myfile"而不是无聊的字符。

Answer 1

Solutions:

1. use C++11 string literals: R"(F:\\somepath\\subpath\\myfile)"

2. Use boost::path with forward slashes: They will validate your path and raise exceptions for problems.

    boost::filesystem::path p = "f:/somepath/subpath"; p /= "myfile"; 

3. just use forward slashes; Windows should understand them.

Answer 2

If you have C++11, you can use raw string literals:

std::string s = R"F:\somepath\subpath\myfile";

On the other hand, you can just use forward slashes for filesystem paths:

std::string s = "F:/somepath/subpath/myfile";

Answer 3

Two obvious options:

1. Windows understands forward slashes (or rather, it translates them to backslashes); use those instead.

2. C++11 has raw string literals. Stuff inside them doesn't need to be escaped.

    R"(F:\\somepath\\subpath\\myfile)"
