How to store a single "\"

[geenweb]

Close this question.
I see that it saves as "\\", but when it reads in the value is "\". I assume this must be JSON standard.

I need to have a single backslash as a value in a JSON file. When the following line of code is executed:
data["key_fields"][0]["1"]["char"] = "\";

It creates:

"key_fields": [
  {
    "1": {
      "char": "\\"

Is there any workaround for this?

Thanks

This is correct since backslashes need to be escaped. Try:

std::string slash = data["key_fields"][0]["1"]["char"];
std::cout << slash << std::endl;
