extracting a string from string when a string exist

Hi....

I want to do following......... I have a string... "service-name-you" I want to get string "you" extracted only if the "service" is the first item before the first "-"


following is the code I have so far.....

Code:

---

    for (loop = 0; loop < numEntries; loop++)
    {
        strsplit = strstr(entries[loop].name,"services-");
        strsplit = strstr(strsplit,"-");

        if((serviceName = strchr(strsplit,'-')) != NULL)
            strcpy(serviceName,serviceName+1);
        LOGINFO("Somiiii restrictions %s",serviceName);
    }

---

basically as an example..... entries[loop].name holds string such as....

"you-me-other"
"me-all-you"
"service-name-you"

numEntries = 3 in this case.

So when it hit "service-name-you" and has "service" in it I want to extract "you"
out of it

Please help me as I am struggling......

Thanks alot in advance

Code:

---

if( sscanf( buf, "%[^-]", word ) == 1 && strcmp( word, "service" ) == 0 )
    ptr = strstr( buf, "you" );

Code:

---

    if( sscanf( buffer, "%*[^-]-%*[^-]-%s", extract ) == 1 )
        printf("%s\n", extract );

Your example isn't checking to see if the first word is "service".

I was clearly on a illusion on showing the OP how to extract a sub string froma string. But wasn't intended in giving him a solution. Perhaps i could have included :)

Code:

---

ptr = strrchr( buf, '-' );
if( ptr )
    sscanf( ptr+1, "%s", word );

I believe it's your turn.

How about this :D

Code:

---

    if( sscanf( buffer, "service-%*[^-]-%s", extract ) == 1 )
        printf("%s\n", extract );

Thanks so much for helping kindly

I am commenting on the code so I could try to understand....I do not have C compiler right now so I can't test things.....hope you will understand and help me...

Code:

---

//This basically extract "service" and verify it has service in it.
if( sscanf( buf, "%[^-]", word ) == 1 && strcmp( word, "service" ) == 0 )
    ptr = strstr( buf, "you" ); //This pretty much get the pointer to the first char where it find the word you

---

but its is little more complected. there can be strings.....where

"service-name-you"
"service-name-you1"
"service-name-you2"
"service-name-you3"

I want to extract the last word...."you", "you1", "you2", "you3" when the submitted string has "service".
