Is there are an easier way of serializing a vector attribute of an object in c++ using sqlite3?

I can serialize an object if it's class definition has attributes. So if I have an object whose class does not have attributes, do I serialize the attributes importedi in it's class definition? For example; suppose I have the following class, #ifndef BREAD_H #define BREAD_H #include "EGGS.h"; #include "FLOUR.h"; class …

So I'm trying to remove 2 brackets from lines I'm reading from a file. For some reason when I run my program the characters in between the delimeters is removed. for example `greetings pe()ple` would end up as `greetings pe` I'm using a char array of delimiters. `char delimiters[] = …

The sign-extend unit works for I-type instructions, what would be it's output for R-type instructions? 32 zeros?

Are these two instructions equivalent, i.e do they both do the exact same thing? `addi $s0,$s0,0` and `add $s0, $s0, $zero`

I recently moved both my eclipse and Android folder into the same location. I didn't know that this would mess up eclipse. My themes are gone and eclipse can no longer locate the Android SDK. I've looked for ways to fix this online but most of the answers involve reinstalling …

I'm trying to create a list stack that implements some interface called SomeList The list stack should only use stack with no links. the itnerface has a number of methods that I would like to implement. So for SomeList I have something like public interface SomeList<T>{public void plus(T something);public E …

This method is supposed to reverse a stack by making a new stack and pushing popped items from this stack to the revertStack and then returning the reverted stack. When I run some tests, it returns an empty stack in stead. Any clues? public LinkedStack<E> reversed() { LinkedStack<E> revertStack = …

Reverse method won't work This method is supposed to return a copy of a this object, reversed. So it creates a new stack called that such that when all the items from this are popped onto that, this will reference that and the `reversed()` method will return this. When this …

I'm having trouble pinpointing the exact definition of a generic linkedstack class Suppose I have public class LinkedStack<T> { //some variables //would this be right LinkedStack(){ } //for a generic constructor of type T for the LinkedStack class of type T? }

I have a stack method that's supposed to return a reversed *copy* of the this object. I need this to link this to that, the reversed copy of the this stack. Thanks public FancyStack<E> reversed() { FancyStack<E> that= new FancyStack<E>(); if(this.isEmpty()){ return this; } else{ while(top!=null) { revertStack.push(pop()); } } …

I have a generic LinkedStack class with a LinkedStack reversed method It creates a new LinkedStack say newLinkedstack and pushes items from the current stack by popping them. So at the end of the operation the current stack is left empty and newLinkedStack contains the same items/elements that were in …

Hi I'm trying to write a toString() method for a generic LinkedStack but I'm having trouble My class has two push methods. One pushes elements of some type onto the stack. It takes in some generic element and pushes it onto the stack. The other method takes in some generic …

Suppose I have a class with a constructor that takes in two strings is it okay to write the constructor this way? public class box{ private String s1; private String s2; public box(**String str1,String str2**){ s1=str1; s2=str2; } } Or can I just say public box(String str1,str2)?
