say have elements <country>, , elements have lots of subelements <name>, <population>, <cities>, of have own subelements. if call

for $x in doc("myfile.xml")/world return <country> { $c/country } </country>

then i'll of countries, of subelements, subelements, , on. however, want select of cities in country, including subelements of cities. how can this?

you use xpath expressions select elements in xquery.

  • $x/country/* selects child elements of country.
  • $x/country/cities selects <cities/> child elements
  • $x/country/(name|population|cities) selects specified child elements (| union operator, , parenthesis create sequence)

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
