Answer:

c. StringBuilder

Explanation:

An alternative to the String class would be the StringBuilder Class. This class uses Strings as objects and allows you to mix and match different strings as well as adding, removing, implementing,  and modifying strings themselves as though they were similar to an array. Unlike the string class StringBuilder allows you to modify and work with a combination of strings in the same piece of data as opposed to having various objects and copying pieces which would take up more memory.

Write a method swaparrayends() that swaps the first and last elements of its array parameter. ex: sortarray = {10, 20, 30, 40} b
Alexus [3.1K]
In the C programming language, you can't determine the array size from the parameter, so you have to pass it in as an extra parameter. The solution could be:

#include <stdio.h>

void swaparrayends(int arr[], int nrElements)
{
int temp = arr[0];
arr[0] = arr[nrElements - 1];
arr[nrElements - 1] = temp;
}


void main()
{
int i;
int myArray[] = { 1,2,3,4,5 };
int nrElements = sizeof(myArray) / sizeof(myArray[0]);
swaparrayends(myArray, nrElements);

for (i = 0; i < nrElements; i++)
{
printf("%d ", myArray[i]);
}

getchar();
}

In higher languages like C# it becomes much simpler:

        static void Main(string[] args)
        {
            int[] myArray = {1, 2, 3, 4, 5};
            swaparrayends(myArray);
            foreach (var el in myArray)
            {
                Console.Write(el + " ");
            }

            Console.ReadLine();
        }

        static void swaparrayends(int[] arr)
        {
            int temp = arr[0];
            arr[0] = arr.Last();
            arr[arr.Length - 1] = temp;
        }

The implementation stage of the SDLC _____.
Karolina [17]

Answer:

d. involves analyzing end-user business requirements in order to refine project goals

Explanation:

In the software development life cycle, the implementation stage is the stage where the computer programmers begin the actual coding of the application required by the end-user. At this stage, the developer takes into account the needs and specifications of the customer.

For example, if the end-user wants a software application that can track payment records, the researcher at this stage begins using the right software to code programs that can effect this function.
