Basic string manipulation question

[Vijjuuu]

find the @ character position , copy the string from that position to end of the actual string

[Jose David Pujo]

Simple function:

int GetDomain (const char /*IN*/*email, char /*OUT*/*domain)
{
if (!email || !domain) return -1; // err 1
char *c= strchr ((char*)email, '@');
if (!c) return -2; // err 2
strcpy (domain, c+1);
return 0;
}

...

char a[100]="";
int e= GetDomain ("sample@domain.es", a);

const char * getDomain(const char szMail)
{
const char * szDomain;
if (! szMail ) return NULL;

szDomain = szMail +strlen(szMail);
while (szDomain-- != szMail )
{
if (*szDomain == '@') break;
}

if (szDomain==szMail) return NULL;

return ++szDomain;
}

I'm leaving error checking and other dodgy stuff to you as an exercise. :-\

const char *szEmail= "myname@mydomain.com";
std::cout<< strstr(szEmail, "@")+1 <<std::endl;

Output: mydomain.com

Good try, i've got another one:

char *email="myemail@mail.com";
char *domain= strchr(email,'@')?strchr(email,'@')+1: 0;

Its simple using CString class

CString sEmail, sDomain;
sEmail = "random@mail.com";
int nPos = sEmail.Find("@");
sDomain = sEmail.Mid(nPos + 1, sEmail.GetLength());
