validation on exact length of numeric field in laravel 5 -


i have numeric field want validate on exact fill 4 digits.

like: 1234, 4567,1245

but these invalid inputs: like: 123, 346, 45m6, 34567

what trying:

'last4digits'             => 'numeric|between:4,4',

you looking digits rule. from docs:

the field under validation must numeric , must have exact length of value.

'last4digits' => 'digits:4'

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.
