just a simple| simple QUESTION:)

i was just playing around with the web server and found that I did not know one thing.

When I declare a variable like this:

char buf[1000];

--
Now when I put this code in:

e = 0;
buf[e] = "\\";

--

Will

buf[e]

have the string "\\" ?

And if I do something like this

buf[e] = 0;

Will it erase the string already in buf[e] , which is "\\", or will it leave this string in there ?


Please, that is a kind of urgent, and I know that is just a little newbie answer for you:p

Code:

---

e = 0;
buf[e] = "\\";

---

This won't work because "\\" is a string. Try using '\\\\'. However, since buf[e+1] probably won't be '\0' anything that tries to print a string will fail.

OK something's gone screwy so the character to use is: ' \ \ ' (that's got double spaces in)

No, I am using "\\" (without any space between then)

It is working fine. The server can display the spcific file but because It was a tutorial, and I am not getting this code ( I am not understanding why and what it is doing)

Code:

---

  d=recv(wparam,aa,1000,0);
        abc(aa);
                        p=aa + 4;
                        e=0;
                        while(*p!=32)
                        {
                                if (*p=='/')
                                {
                                        buf[e]='\\';   
                                }
                                else
                                        buf[e]=*p;
                                if(buf[e]=='.')
                                        fn=1;
                                p++;
                                e++;
                        }
                      buf[e] = 0;  //PLEASE SEE BELOW
                                                `
                        if (strlen(buf)==1)
                                strcpy(filename,"c:\\website\\woo\\index.html");
                        else
                        {
                                strcpy(filename,"c:\\website");
                                strcat(filename,buf);

                                if(fn==0)
                                        strcat(filename,"index.html");
                        }

---

I am also confused at this line where I commented in red colour

buf[e] = 0

Why do I need put it back to 0?

-------------------

You are intelligent enough to know this parskie! Are not you:D

Ohh, Another thing in the code:

abc() is just function to write the given characters to a file:D

Since e has been incremented, it will ensure that the string is null-terminated :)
