vb.net - Generating a new random number for each iteration -


the following code attempting position pieces @ random positions on board:

function selectplayer()     dim rand new random()     dim player integer = rand.next(0, 3)     return player end function  function selectpiece()     dim rand new random()     dim piece integer = rand.next(0, 4)     return piece end function   sub randomiseboard(byref board(,) string)      dim players() string = {"w", "b", "  "}     dim pieces() string = {"g", "e", "n", "m"}      rankno = 1 boarddimension         fileno = 1 boarddimension             board(rankno, fileno) = players(selectplayer) & pieces(selectpiece)         next     next  end sub

the type of piece chosen array, containing character represents them, , combined player (b / w) uniquely define piece.

when executed, board generated, same piece positioned in every square.

each time code run, new piece generated , displayed. yet - not select unique piece each iteration.

why this? how can solve this?

initialize random-number generator.

randomize()

then generate random value

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.
