Code:

int k=1;
while (k==1)

{
 
    if(d1 && d2 && d3 <= ra && rb && rc)
    {
      cerr << "Circles A B and C contain point (" << xq << " ," << yq << "). " << endl;
      exit (10);
    }

    else if (d1 && d3 <= ra && rc && d2 >= rb)
    {
      cerr << "Circles A and C contain point (" << xq << " ," << yq << "). " << endl;
      exit(20);
    }

    else if (d3 >= rc && d2 && d2 <= ra && rb)
    {
      cerr << "Circles A and B contain point (" << xq << " ," << yq << "). " << endl;
      exit(30);
    }

  else if (d1 >= ra && d2 <= rb && d3 <= rc)
    {
      cerr << "Circles B and C contain point (" << xq << " ," << yq << "). " << endl;
      exit(40);
    }

      exit(50);
    }

  else if (d1 && d3 >= ra && rc && d2 <= rb)
    {
      cerr << "Circle B contains point (" << xq << " ," << yq << "). " << endl;
      exit(60);
    }

  else if (d1 && d3 >= ra && rc && d2 <= rb)
    {
      cerr << "Circle C contains point (" << xq << " ," << yq << "). " << endl;
      exit(70);
    }
   
  else if (d1 && d2 && d3 >= ra && rb && rc)
    {
      cerr << "No circle contains point (" << xq << " ," << yq << "). " << endl;
      exit(80);
    }
 
 }

The loop does not exit because k is never changed (or referenced) inside the loop. Your code had several problems. Note the read areas. You MUST COMPILE with WARNINGS enabled! Correct code has ZERO warnings. At a minimum, assuming the logic is correct. The code you posted could not have compiled without warnings. You still need to set k to zero somewhere in the loop code.

drop_text_search_template

DROP TEXT SEARCH 
TEMPLATE(7)				  PostgreSQL 9.2.7 Documentation			      DROP TEXT SEARCH TEMPLATE(7)

NAME

       DROP_TEXT_SEARCH_TEMPLATE - remove a text search template

SYNOPSIS

       DROP TEXT SEARCH TEMPLATE [ IF EXISTS ] name [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP TEXT SEARCH TEMPLATE drops an existing text search template. You must be a superuser to use this command.

PARAMETERS

       IF EXISTS
	   Do not throw an error if the text search template does not exist. A notice is issued in this case.

       name
	   The name (optionally schema-qualified) of an existing text search template.

       CASCADE
	   Automatically drop objects that depend on the text search template.

       RESTRICT
	   Refuse to drop the text search template if any objects depend on it. This is the default.

EXAMPLES

       Remove the text search template thesaurus:

	   DROP TEXT SEARCH TEMPLATE thesaurus;

       This command will not succeed if there are any existing text search dictionaries that use the template. Add CASCADE to drop such
       dictionaries along with the template.

COMPATIBILITY

       There is no DROP TEXT SEARCH TEMPLATE statement in the SQL standard.

SEE ALSO

       ALTER TEXT SEARCH TEMPLATE (ALTER_TEXT_SEARCH_TEMPLATE(7)), CREATE TEXT SEARCH TEMPLATE (CREATE_TEXT_SEARCH_TEMPLATE(7))
