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

Question

Suppose I have a string entered by the user asdfgh\hjand I want to find out the index of the character \in String. How can I do this in C?

I tried the strchr()function as strchr("asdfgh\hj",'\'), but the compiler throws an error.

Then I used the operator ==, but with the same problem with it - again, the compiler throws an error.

In C, backslashes are used for hard typed characters, such as \n. Therefore, you need to write \\for yourself \:

char *backslash = strch("some text containing \\ ...", '\\');

Please note that the line you provided \must also be written \\, otherwise it will be considered \hwhich does not matter.
