Can I build an array using a loop in Ruby? -

-

i started learning ruby/rails, , trying write program builds array, formats new array.

it works second while, and, if have array built, second part works well. there leaving out? 

chap = [] page = [] linewidth = 80 x = 0 n = chap.length.to_i puts 'chapter?' chapter = gets.chomp while chapter != ''   chap.push chapter   puts 'page?'   pg = gets.chomp   page.push pg   puts 'chapter?'   chapter = gets.chomp end puts ('table of contents').center linewidth puts '' while x < n  puts ('chapter ' + (x+1).to_s + ' ' + chap[x]).ljust(linewidth/2) +(' page ' + page[x]).rjust(linewidth/2)  x = x + 1 end

thanks help!

simple pilot error: called

n = chap.length.to_i

too early. have length of chap list after put things in it. move line here:

    ...     puts 'chapter?'     chapter = gets.chomp end n = chap.length.to_i  puts ('table of contents').center linewidth

and works fine.

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.
