Write a program whose input is an email address, and whose output is the username on one line and the domain on the second. example: if the input is:

pooja@piazza. com

then the output is

username: pooja

domain: piazza. com

the main program is written for you, and cannot be modified. your job is to write the function parseemailaddress defined in "util. cpp" the function is called by main() and passed an email address, and parses the email address to obtain the username and domain. these two values are returned via reference parameters. hint: use the string functions .find() and .

main. cpp is a read only file

#include
#include

using namespace std;

// function declaration:
void parseemailaddress(string email, string& username, string& domain);

int main()
{
string email, username, domain;

cout < < " enter a valid email address> ";
cin > > email;
cout < < endl;

parseemailaddress(email, username, domain);

cout < < "username: " < < username < < endl;
cout < < "domain: " < < domain < < endl;

return 0;
}

/*util. cpp*/ is the todo file

#include
#include

using namespace std;

//
// parseemailaddress:
//
// parses email address into usernam and domain, which are
// returned via reference paramters.
//
void parseemailaddress(string email, string& username, string& domain)
{
//
// todo: use .find() and .substr()
//

username = "";
domain = "";

return;
}
