php - How to select data between dates where the checkin and checkout field type is in varchar? -


this question has answer here:

i want select data between dates table

for eg:guestrocordtransac(tbl name)

id,roomno,roomtype, checkin,       checkout  1  101      baywatch  05/17/2015 05/24/2015  2  102      baywatch  05/10/2015 05/16/2015

when tried writing query 1 roomno 101

select roomno guestrocordtransac checkin between "05/14/2015" , "05/29/2015"

the correct answer fix data date values stored date/times. better use native database types values.

the second best thing (and remote second best) conversion on fly:

select roomno guestrocordtransac str_to_date(checkin, '%m/%d/%y') between '2015-05-14' , '2015-05-29';

when using date constants, use iso standard format of yyyy-mm-dd.

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.
