I am trying to print a parenthesis using: printf("\)"); However, it is giving me the following warning: warning: unknown escape sequence '\)'

I can't seem to find a clear explanation anywhere on how to fix this. I realize it's just a warning, but since it's still treating that as a parenthesis it's throwing off all my other parentheses and giving me errors so that the code does not compile.

EDIT: Treating it as a regular character and just saying printf(")") is not working. It's still mismatching all the parentheses and I have gone through multiple times to make sure I'm not actually missing any.

    Parentheses are not special characters in C string or character literals, they don't need to be escaped. – Some programmer dude Mar 06 '16 at 07:04

    Drop the escape sequence. Use just `")"`. See http://stackoverflow.com/a/34958449/434551 for valid escape sequences. – R Sahu Mar 06 '16 at 07:05
  • I was treating it as a regular character and it was still throwing off all of my parenthesis, that's why I tried escaping it. – user5799707 Mar 06 '16 at 07:07
  • I'm not getting any warnings/errors on my computer... (http://rextester.com/MTOR1328) – Idos Mar 06 '16 at 07:17
  • Nevermind, I'm stupid and was recursively calling a function by the wrong name, which gave me errors related to parenthesis so I assumed it had to be the print statement. – user5799707 Mar 06 '16 at 07:23
  • Happens to the best of us... Anyways cheers for figuring it out – Idos Mar 06 '16 at 07:24

The warning is coming from the C compiler. It is telling you that \ is not a known escape sequence in C. You need to double-escape the slash, like so: \\

Edit: if you just want to print the parenthesis, i.e. the ) then drop the slash altogether and use:

printf(")");

try this:

#include <stdio.h>

int main()
{
  printf("Printing quotation mark \")\" ");
}

you need to add an escape character to get the quote to print which in this case is \"

This will result in Printing quotation mark ")"

just write parenthesis in double quote " " ,because parenthesis is not a escape character .

try this :

 #include<stdio.h>
 int main(){
 printf( "(  )" ); // print  parenthesis here
 }

Hope this helps.

Using variables seems to be a viable solution using my compiler.

#include <stdio.h>

int main() {
    char var = ')';
    printf("Hello, World!\n");
    printf("Success :%c",var); //As you can see this is one way to go about the problem
    return 0;
}
