In C how do I find the '\' character in a string?

Question

Suppose I have a string entered by the user `asdfgh\hj`, and I wish to find out the index of `\` character in a String. How I can do it in C? I tried `strchr()` function as `strchr("asdfgh\hj",'\')` but compiler throws an error. Then I used `==` operator but same problem with it — again the compiler throws an error.

That's the right function! The reason you get an error is because `\` is a special "escape" character. It is used to define "special" non-printable characters, such as newline `
`. That is why the backslash itself `\` needs escaping, like this:

```
strchr("asdfgh\hj",'\')
```
