php - Addition of two matrix using loop -


these 2 matrices in 4 arrays:

array (     [0] => array         (             [0] => 1             [1] => 2         )      [1] => array         (             [0] => 4             [1] => 5         )  ) array (     [0] => array         (             [0] => 1             [1] => 2         )      [1] => array         (             [0] => 4             [1] => 5         ) )

how can add these matrices using loop?

try this:-

<?php  $a1 = array('0' => array('0' => 1,'1' => 2),'1' => array('0' => 4,'1' => 5));   $a2 = array('0' => array('0' => 1,'1' => 2),'1' => array('0' => 4,'1' => 5));  $sumarray = array();  $result = array(); for($i=0; $i<=1; $i++) {     for($j=0; $j<=1; $j++) {         $result[$i][$j] = $a1[$i][$j] + $a2[$i][$j];     } } echo "<pre/>";print_r($result); ?>

output:- http://prntscr.com/75hoqi

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.
