Answer:

Your arms should be comfortable at your side, forming a 45° angle with your upper arms, and your forearms should be parallel to the floor.

Position the keyboard directly in front and close to you so you don't have an excessive reach.

If you are working for a long period of time, alternate between sitting and standing. Take breaks to stretch.

Keep your shoulders, arms, hands and fingers relaxed.

Position your wrists straight or in neutral position while typing.

Adjust your chair height and position so your feet rest flat on the floor, or add a footrest to compensate for a higher chair.

Adjust the keyboard height so that your shoulders can relax and your arms are straight in front of you.

Keep the wrist in a neutral position: parallel to your desk and the middle finger must be in line with the wrist and forearm.

Don't rest your wrist while typing, let it float. Only rest your wrist while you are NOT typing.

Use a light touch when pressing keys.

Don't stretch your fingers to reach for faraway keys. Instead move your arm to position your finger over the key and then hit it.

Do not hold your thumbs rigid or your pinkies up. Curve your fingers.

Don't use two fingers of one hand for two-key combinations. Use one finger of one hand to hold Shift, Ctrl, or Alt down, and then hit the second key with a finger from the other hand. this is the way of typing :)

You are writing a program that defines a variable within a loop, and then tries to use that variable outside the loop. However,

Law Incorporation [45]

Answer:

The Variable is out of scope

Explanation:

In programming variables exists with scopes This could be local or global. When a variable is declared as a global variable it is available to all methods and procedures in the program. Java programming language as well as C++ and several others use the open and close braces to define the scope in programs. consider the following example

public class ANot {

public static void main(String[] args) {

int i = 0;

while ( i<10){

int sum = 0;

sum = sum+i;

}

}

In this example, the variable i is global and can be assessed within the while loop but the variable sum is local to the while loop and cannot be assessed outside of it

<h3>What is a Key Combination?</h3>

This refers to the procedure that is used to combine two or more keys on the keyboard to execute a task.

Hence, we can see that the procedure that can be used to carry out the operation is:

Enter the screen you want to capture and print
Press the Function key, followed by the PrtScr. Please note this can vary slightly, depending on the keyboard.

Program 4 - Pick color Class Create a class that randomly pick a color from an array of colors: string colors[7]; Have the color

xxMikexx [17]

Answer:

#include<cstdlib>

#include<bits/stdc++.h>

#include<time.h>

using namespace std;

class Colors{

string colors[7];

public:

void setElement(int,string);

void printAllColors();

void printRandomColor();

};

void Colors::setElement(int index,string color){

colors[index] = color;

}

void Colors::printAllColors(){

cout << "Printing all the colors:\n";

for(int i=0;i<7;i++){

cout << colors[i] <<"\t";

}

void Colors::printRandomColor(){

srand (time(NULL));

int index = rand() % 7;

cout<< "\n\nThe random picked color:";

cout << colors[index] << endl;

}

int main(){

Colors color;

color.setElement(0,"red");

color.setElement(1,"orange");

color.setElement(2,"yellow");

color.setElement(3,"green");

color.setElement(4,"blue");

color.setElement(5,"indigo");

color.setElement(6,"violet");

color.printAllColors();

color.printRandomColor();

}

to get the random color we are using srand and rand function. we are using time as seed to srand() function,because every time the time is changed. And based on that we are using rand() function and doing mod with 7 with the random number to get the index between 0 to 6, as ut array size is 7(0 to 6).

In the setElement(int index,string color) method we are inserting the value of colors in the colors array based on index.

In the printAllColors() function we are printing all the colors in the array.

In the printRandomColor() er are printing any random color based on rand() function.

and in main() we are initializing the string array with colors and calling the functions.
