security - Object of curretUser - Is it safe -


i sitting programming "atm/internetbank" school assignment , wondering "safety" of creating object save currentuser. "atm" should able run @ laptop. "atm" assignment there related database. when log-in matching username , password saves info balance user object currentuser. question is, how safe password , balance. possible manipulate info outside program. thinking of getting balance when needed directly database , directly updating balance when new has happened. in advance.

first atms , web banks different in atms assume physical security of client while web sites have little physical security.

that said, server need data. feel free keep data in server side session object. guess during data in memory on client safe there isn't need.

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.
