Python Input Function -

-

i wondering if tell me wrong code, when run code shows nothing if take out "elif" work.\

first=input("what first name? "); middle=input("what middle name? "); last=input("what last name? "); test = [first, middle, last]; print (""); print ("firstname: " + test[0]); print ("middlename: " + test[1]); print ("lastname: " + test[2]); print (""); correct=input("this information input, correct? "); if (correct == "yes" or "yes"):     print ("good!") elif (correct == "no" or "no"):     print ("sorry there must error!");

here's problem:

if (correct == "yes" or "yes"):     # ... elif (correct == "no" or "no"):     # ...

it should be:

if correct in ("yes", "yes"):     # ... elif correct in ("no", "no"):     # ...

notice right way make comparison involving several conditions this:

correct == "yes" or correct == "yes"

but gets written this, shorter:

correct in ("yes", "yes")

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
