sql - How can I change this query into a subquery - 


select c.name, c.tel customer c, vehicle c, hire h c.cid=h.cid , v.vid = h.vid , (dropoff-pickup) > 1 , v.make = 'suzuki'

dropoff , pickup date fields 

select c.name, c.tel customer c join hire h on c.cid = h.cid join vehicle v on h.vid = v.vid v.make = 'suzuki'  , (h.dropoff-h.pickup) > 1

not answer question don't need subquery here please structure query make more obvious trying (you getting customer name , telephone number vehicles make suzuki length of hire longer 1 day right?)

structuring queries make more readable people don't know trying , make finding mistakes in query logic easier or others

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.
