Check if character equals \ in C++

Question

I'm trying to see if a character c equals \

if (c == '\')
 //do something

I don't know exactly how this is called but everything after \ turns in a character string.

Answer 1

Backslash is used as the escape character in C++, as it is in many other languages. If you want a literal backslash, you need to use \\:

if (c == '\\') {

}

Answer 2

\ backslash is an escape character.

Escape sequences are used to represent certain special characters within string literals and character literals. Read here

So you should do:

if (c == '\\'){
}
