Answer:

1.RGB: Best for projects intended to be used on the web or video

Explanation:

On websites or making project RGB combination of colors is used. This combination of colors is used to store images in electronic components.

2. CMYK: best for professional printing projects using process colors

Explanation:

Printing professional use CMYK combinations of color for better printing results.

3.) indexed:The only colors saved are the colors used in the image

To manage digital images we use Indexed mode of colors.

Explanation:

4.) bitmap: uses black and white

Explanation:

bitmap is the combination of the black and white colors. As the images are large in size so that, to reduce the size of the image we store image in bitmap to reduce the size.

5.) gray scale: uses different shades of grey

Explanation:

The different shades of gray colors are found in the gray scale. These shades are used to produce images.

Compare and contrast the role that business users play when software is developed using Waterfall and Agile software development

qaws [65]

Answer: Both Agile and waterfall model are software development models to deliver a final outcome in the form of a software product. Waterfall model is sequential process with the requirements beings rigid and defined before beginning the software development.

Agile method basically concerned with the requirements of the client. Here both testing and development is carried out at the same time.

Explanation:

More differences between the two include :

Waterfall model is easy to manage whereas in agile model as the the client requirements changes and wants more functionalities is becomes a bit more difficult to manage. the role of project manager is very crucial in waterfall model whereas the role of developers ans testers is more important in Agile model.

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;
}

Answer:

#include <iostream>

using namespace std;

int main()

{

char address[2];

int tag, firstBit, secondBit, setNumber;

int cache[4][2]={{1,5}, {2,4}, {3,2}, {6,0}};

cout << "Enter the address as hex(in small letters: "<

cin >> address;

for (int i < 0; i < 8; i++){

if (address[0] == '0'){

tag = 0;

firstBit = 0;

} else if (address[0] == '1'){

tag = 0;

firstBit = 1;

} else if (address[0] == '2'){

tag =1;

firstBit = 0;

} else if (address[0] == '3'){

tag = 1;

firstBit = 1;

} else if (address[0] == '4'){

tag = 2;

firstBit = 0;

} else if (address[0] == '5'){

tag = 2;

firstBit = 1;

} else if (address[0] == '6'){

tag = 3;

firstBit = 0;

} else if (address[0] == '7'){

tag = 3;

firstBit = 1;

} else if (address[0] == '8'){

tag = 4;

firstBit = 0;

} else if (address[0] == '9'){

tag = 4;

firstBit = 1;

} else if (address[0] == 'A'){

tag = 5;

firstBit = 0;

} else if (address[0] == 'B'){

tag = 5;

firstBit = 1;

} else if (address[0] == 'C'){

tag = 6;

firstBit = 0;

} else if (address[0] == 'D'){

tag = 6;

firstBit = 1;

} else if (address[0] == 'E'){

tag = 7;

firstBit = 0;

} else if (address[0] == 'F'){

tag = 7;

firstBit = 1;

} else{

cout<<"The Hex number is not valid"<< endl;

}

if(address[1]>='0' && address[1]<'8'){

secondBit = 0;

} else if(address[1]=='8'|| address[1]=='9'||(address[1]>='a' && address[1]<='f')){

secondBit = 1;

} else{

cout<<"The Hex number is not valid"<< endl;

return 0;

}

setNumber = firstBit * 2 + secondBit;

if(cache[setNumber][0]==tag || cache[setNumber][1]==tag){

cout<<"There is a hit";

} else{

cout<< "There is a miss";

}

return 0;

}

Explanation:

The C++ source code prompts the user for an input for the address variable, then the nested if statement is used to assign the value of the firstBit value given the value in the first index in the address character array. Another if statement is used to assign the value for the secondBit and then the setNumber is calculated.

If the setNumber is equal to the tag bit, Then the hit message is printed but a miss message is printed if not.
