Quotation marks and strings - in C

Hello,
I writing a program, and I don't know how to insert quotation marks in my code.
For example,

Code:

#include <stdio.h>

#include <stdlib.h>

#include <string.h>



int main()

{

        char url[100] = "http://www.google.com";



        printf("%s", url);

        printf("\n");



        return 0;



}

How would I get url, to store "http://www.google.com", and not http://www.google.com.

Any help would be appreciated.

You have to put in an escape sequence to get a literal double-quote:

Code:

char url[100] = "\"http://www.google.com\"";

Hello, I have a new problem, if anybody can help.

Code:

#include <stdio.h>

#include <stdlib.h>

#include <string.h>



int main()

{

        char url[35] = "\"http://www.google.com\"";





        execl("/usr/bin/wget", "wget", url, 0);





        return 0;



}

When I try to run this program, I get the following error.
--04:21:04-- ftp://%22http//www.google.com%22
=> `www.google.com"'
Resolving %22http... failed: Host not found.
Why is it adding %22 to my code. When I print it, it works. 22 in hex, is the quotation marks, why is it changing them. It compiles fine.

You wouldn't need the double quotes in the argument, would you?

Code:

[root@inet root]# wget http://www.google.com

--08:06:48--  http://www.google.com/

          => `index.html'

Resolving www.google.com... done.

Connecting to www.google.com[64.233.167.104]:80... connected.

[root@inet root]#

Try it without and see if that works.
