c# - Get all nodes in a tree -


i have little issue following program

internal ienumerable<t> getitems<t>(string nodename) t : root, new() {     var node = new t();     return getitems(nodename, node).cast<t>(); }  public ienumerable<root> getitems(string nodename, root root) {     // }

i know how change c++ code. have tried

template<class t> list<t> getitems(string nodename) {     auto node = new t();     return getitems(nodename, node); }  list<root> getitems(string nodename, root root) {     // }

now mess little 

typedef shared_ptr<root> root_ptr; class smallroot:public root{}; list<root_ptr> getitems(string nodename, root_ptr rootptr) {     //do , return list of share pointers       }

then stuck @ how redesign template getitems feed smallroot classes

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.
