What are the main features of arrays. How are arrays used and created?

AnswerWhat is an array: In programming languages, an array is a way of storing several items (such as integers). These items must have the same type (only integers, only strings, ...) because an array can't store different items. Every item in an array has a number so the programmer can get the item by using that number. This number is called the index. In some programming languages, the first item has index 0, the second item has index 1 and so on. But in some languages, the first item has index 1 (and then 2, 3, ...).


What is dimentions arrays in java?

You can make arrays with any number of dimensions (depending on RAM limitations, of course). However, internally, a two-dimensional array (for example) is stored as an array of arrays; that is, each first-level array contains an array of the second level. Similarly with higher dimensions.


What is the difference between C plus plus and the D language?

D essentially evolved from practical usage of C++ and added features found in other languages including C#, Eiffel, Java, Python and Ruby. D has garbage collection, design by contract, unit testing, true modules, first class arrays, associative arrays, dynamic arrays, array slicing, nested functions, inner classes, closures, anonymous functions, compile time function execution, lazy evaluation, a re-engineered template syntax and integrated inline assembler.


What is the use of auxiliary array in merge sort?

In merge sort the whole is divided into two sub arrays. (This way of solving problem is called Divide and conquer algorithm) These sub arrays are called auxiliary arrays. First an array A is divided into two auxiliary arrays A1 and A2. Now these auxiliary arrays are further divided until we reach a stage with an auxiliary array of 2 elements. These 2 elements are arranged in incremental order and merged with the previous divided arrays. So we can say that auxiliary array is used to implement the basic principle of merge sort.


Is the First Generation Language machine dependent?

Yes. Both first and second generation languages are machine-dependent. The first generation of languages were machine code, while the second were assembly languages. Non-machine dependency came about with the advent of the third-generation of languages, all the high-level languages.

What are first position mortgage notes?

First position mortgage notes are a secure real estate contract that indicates an amount owed on a property. The position is an indicator of who has first rights of foreclosure should the payor default on the loan. In the private cash flow notes business most investors are interested in first position notes and second or other (3rd, 4th) position notes are not as valuable due to the risk involved of possibly losing the investment in a foreclosure situation. the lower position notes would have to pay off the first or stand to lose their investment entirely.

What is the median of two arrays when combined into a single array?

To find the median of two arrays when combined into a single array, first merge the arrays and then calculate the median by finding the middle value if the total number of elements is odd, or by averaging the two middle values if the total number of elements is even.


How are entire arrays passed from one method to another?

In some programming languages, like C, you can pass the new method (or function) an address pointer to the first element in the array. As long as you don't leave the scope of the method the array was created in, the array will remain valid. In other languages that don't support memory addresses, like FORTRAN, it must be done by making the array global.
