javascript - Object in class set as variable -


here javascript:

var error_msg = error_data.validation_msg; if(error_msg) {      for(var i=0; i<5; i++)      {           var answer_exact = 'answer_exact_'+i;           var error = error_msg.answer_exact;      }          }

how can call objects in error_msg class like:

error_msg.answer_exact_0; error_msg.answer_exact_1; error_msg.answer_exact_2; ....

you need use bracket notation property using dynamic key(where property name stored in variable).

var error = error_msg[answer_exact];

your code tries read property named answer_exact object error_msg

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.
