How can you copy one array in to a different array?

How do you add a one more element to existing array?

To add one more element to an existing array, allocate a new array, copy the old elements to the new elements, and deallocate the old array; updating pointers as needed.

Is array is structure or not?

Array is not a struct. Array only has one datatype, struct has arbitrary different datatypes.

How do you merge two array without using function?

Take another array big enough to hold both array copy content of these two array into new one. You merged two array and haven't used a single function.!

Explain the Different types of array?

one dementional array and two dementional array

What is an array and how do you create one How do you access information or elements contained in an array?

An array is:simply a collection of similar objectsHow you create one: (I think)Basically you receive or copy an image and place it in an array and assign it an mage Areray name.How you access info and elementsIt can be accessed by means of a variable name and an index.

How can I double the size of an array efficiently?

To double the size of an array efficiently, you can create a new array with double the capacity, copy the elements from the original array to the new array, and then update the reference to the original array to point to the new array. This process ensures that the array is resized without having to individually resize each element.

How do you swap two arrays in c plus plus using string?

You can't. While a string is a character array, an array is not necessarily a string. Treating arrays as if they were strings simply to swap them is madness. The correct way to physically swap arrays A and B is to copy A to a new array, C, then copy B to A, then C to B. If the arrays are the same size this is not a problem. If they are different sizes, you can only swap them if they are dynamic (not static). This means you must reallocate them. To speed up the process, copy the smallest array to C, first. A much better approach would be to point at the two arrays and swap the pointers instead.

Java program to solve lucky number?

Look at the definition, http://en.wikipedia.org/wiki/Lucky_number , then create an array of integers and start working on it. The sieve method requires you to eliminate certain numbers; you can either replace the eliminated array elements with a marker, or move the non-eliminated elements towards the beginning of the array (overwriting the eliminated elements), or perhaps copy to a different array - depending on whether you want simplicity in programming (putting a marker, such as 0, is probably easier to program), or efficiency.Look at the definition, http://en.wikipedia.org/wiki/Lucky_number , then create an array of integers and start working on it.

How do you pass an array to a copy constructor in c plus plus?

You cannot pass an array to a copy constructor. A copy constructor only accepts a constant reference to the object being copied, which must be of the same class as the object being constructed. An array is not an object of any class, and therefore cannot be used in any copy constructor. Although you cannot pass an array to a copy constructor, you can pass an array to a non-trivial constructor. It is not recommended, however, as there's no way to bounds-check the array being passed, which could result in an invalid object being created -- which is never a good thing. Even if you pass the array and its dimension(s) to the constructor, how can you guarantee those dimensions are valid for the array being passed? And what will you do if they are invalid? After all, you cannot veto the construction of an object once you've called its class constructor. Not knowing why you want to pass an array to a copy constructor, or how you intend to initialise the members via an array, makes it somewhat difficult to determine the best solution for you. However, I would consider using mutators instead of constructors. There's still the problem with bounds-checking but at least you won't have to deal with it during the object's construction.

How is array different in C?

It isn't different.

What are 3 different ways to implement an array of order 4x8?

An array of order 4x8 can either be implemented as a one-dimensional array of order 32 or as a one-dimensional array of order 4, where each element is a one-dimensional array of order 8. In either case, the 32 data elements are allocated contiguously and there is no difference in performance. A third way is to implement the one-dimensional array of order 4 as an array of pointers to separately allocated one-dimensional arrays of order 8. The order 4 array is contiguous as are the order 8 arrays, however they need not be contiguous with one another other. This is the least efficient implementation due to the additional level of indirection required to navigate the array.

What is a sentence for array?

Alexia is looking for a different array at Kamaria's corner store.
