Where (what memory location) is the data read from for the following code:

ORG $3000
LDAA #$C2

Answer:

false

Explanation:

-exec option is not mandatory for the find command.

find will still list out the identified files even in the absence of -exec option.

For example:

find . -name test -print

will print out files with the name 'test' in the current directory. Note that there is no exec option in this example.

Same holds true for find with no additional options at all.

For example:

find .

will list out all files in the current directory.

Answer:

The length of the ladder should be 277.85 meters long

Explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

I have created an illustration and attached it as a photo below to better help you understand the situation. As seen on the illustration the difference in height of Building B from Building A is,

[tex]350m-210m = 140m[/tex]

Now that we have the difference we need to find the length of the ladder which is the hypotenuse between the two buildings. We can calculate this by using the Pythagorean theorem which is the following

[tex]h^{2} = a^{2} +b^{2}[/tex]

Now we can plug in the values and solve for the hypotenuse (h)

[tex]h^{2} = 240^{2} +140^{2}[/tex]

[tex]h^{2} = 57,600 +19,600[/tex]

[tex]h^{2} = 77,200[/tex] ... square root of 77,200

[tex]h = 277.85m[/tex] .... rounded up

Therefore, the length of the ladder should be 277.85 meters long

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Answer:

public class average{

   public static float getAverageOfFours(int[] arr){

       int n = arr.length;

       float sum = 0;

       int count=0;

       for(int i=0;i<n;i++){

           if(arr[i]%4==0){

               sum = sum+arr[i];

               count++;

           }

       }

       float avg = sum/count;

       return avg;

   }

    public static void main(String []args){

        int[] array = {10, 48, 16, 99, 84, 85};

        float result = getAverageOfFours(array);

        System.out.println("The average is "+result);

    }

}

Explanation:

Create the function with one parameter and return type is float.

Declare the variable and store the size of array. Take a for loop for traversing in the array and and check the element is divisible by 4 or not by using if statement. If condition true take the sum and increment the count.

This process continue until the condition is true.

finally take the average and return it.

Create the main function for calling the function with pass the array as argument and also define the array.

After that print the result return by the function.

Shorthand Maxterms=M₃+M₂+M₄+M₆+M₇

Explanation:

For the full explanation of this question refer to the image attached which is of the k-Map of F.As we can see in the k-map that there are only 3 ones.by making 2 pairs of 1 we get the SOP expression.

Rest of them are zero from there we will get the POS expression.

The one's in the k-map represent the Minterms and 0's represent Maxterms and the number written in the box is their respective minterm and maxterm number.Minterms are represented by m and maxterms are represented by M.

Answer:

True: Merge Sort sorts a list using divide-conquer approach.

Merge_Sort(B,p,n)  //p is the starting index of array B and n is the last index.

1. if(p<n)

2.        q ← (p+n)/2    //divides the list into two sub-lists

2.        Merge_Sort(B, p, q) //sorts the left half

3.        Merge_Sort(B, q+1, n) //sorts the right half.

4.        Merge(B, p, q, n)

Merge(B, p, q, n)

1.l ← q-p+1.  //no. of elements in left half

2.m ← n-q  //no. of elements in right half.

3.for x ← 1 to l

4.      Left[x] = B[p+x -1] //The elements of left half are copied to Left array

5.for y ← 1 to m.

6.      Right[y]= B[q+y]  //The elements of right half are copied to right array

7. x ← 1, y ←1

8.for z ← p to n.

9.      if( Left[x] ≤ Right[y] ) // to merge the two lists Left and Right, the    //elements are compared.

10.     {   A[z] ← Left[x]   //smaller one comes to the merged list.

11.          x++. }

12.    else

13.      {   A[z] ← Right[y]

14.          y++ }

Explanation:

The Merge_Sort(A, p, n) algorithm first divides the whole array into two halves. Then again divides the sub-lists into it's halves and so on.

Then using merge algorithm it compares the elements of both halves one by one and keep it in sorted order.

Answer:

False

Explanation:

In a while loop we can increment the counter by any number that we wish. It is not that the counter can only be incremented by one each time through the loop.

Below is an example of a while loop with counter incremented by 5 each time.

int count=0;    //initialize count to 0

while(count<50){    //continue the loop till count is lesser than 50

  cout<<count;   //display the value of count

  count = count + 5;    //increment counter by 5 each time

}

Final answer:

The statement is false; a while loop can increment a counter by any amount based on the code within the loop's body.

Explanation:

The statement that a while loop is limited because the counter can only be incremented by one each time through the loop is false. In programming, a while loop can be used to increment or alter a counter variable by any amount, as dictated by the statements within the loop's body. The control of a while loop is based on a condition, and as long as the condition remains true, the loop will continue to execute.

For example:

int counter = 0;
while (counter < 10) {
   counter += 2; // Increment counter by 2
}

In this example, the counter variable starts at 0 and increases by 2 on each iteration of the loop. You can increment the counter by any number, or even apply other operations to change its value in complex ways.

Answer:

JAVA program to display the array elements both forward and backward is given.

public class MyProgram {

   public static void main(String args[]) {    

     int len = 5;

     int[] courseGrades = new int[len];      

     courseGrades[0] = 7;

     courseGrades[1] = 10;

     courseGrades[2] = 11;

     courseGrades[3] = 9;

     courseGrades[4] = 10;      

     System.out.println("The elements of array are ");

     for(int i=0; i<len; i++)

     {

         System.out.print(courseGrades[i]+" ");

     }  

// new line is inserted    

     System.out.println();      

     System.out.println("The elements of array backwards are ");

     for(int i=len-1; i>=0; i--)

     {

       // elements of array printed backwards beginning from last element

       System.out.print(courseGrades[i]+" ");

     }

// new line is inserted    

     System.out.println();  

   }

}

OUTPUT

The elements of array are  

7 10 11 9 10  

The elements of array backwards are  

10 9 11 10 7  

Explanation:

This program uses for loop to display the array elements.

The length of the array is determined by an integer variable, len.

The len variable is declared and initialized to 5.

int len = 5;

The array of integers is declared and initialized as given.

int[] courseGrades = new int[len];

We take the array elements from the question and initialize them manually.

First, we print array elements in sequence using for loop.

for(int i=0; i<len; i++)

To display in sequence, we begin with first element which lies at index 0. The consecutive elements are displayed by incrementing the value of variable i.

The array element is displayed followed by space.

System.out.print(courseGrades[i]+" ");

Next, we print array elements in reverse sequence using another for loop.

for(int i=len-1; i>=0; i--)

To display in reverse sequence, the last element is displayed first. The previous elements are displayed by decrementing the value of variable i.

At the end of each for loop, new line is inserted as shown.

System.out.println();

The length and elements of the array are initialized manually and can be changed for testing the program.

Loops are used to perform operations that would be repeated in a certain number of times; in other words, loops are used to perform repetitive and iterative operations

The loop statements are as follows:

for(int i = 0; i<sizeof(courseGrades)/sizeof(courseGrades[0]);i++){

       cout<<courseGrades[i]<<" ";

   }

cout<<endl;

   for(int i=sizeof(courseGrades)/sizeof(courseGrades[0]) - 1; i >=0; i--){

       cout<<courseGrades[i]<<" ";

   }

cout<<endl;

The flow of the above loops is as follows

The bootstarp loader is also know as bootstrapping a bootstrap loader is usually located in EPROM (erasable programmable read only memory). It is a non volatile memory. The booststrap loader is automatically exicuted by the processor when we turn on the computer.Non volatile memory is that memory in which retain their content even when the power is swithed off.

Answer: Bootstrap program is generally found in the ROM (read only memory) else EEPROM (Electrically erasable programmable read-only memory)

Explanation:Bootstrap loader or program is referred as the program that gets into action or execution when there is the rebooting process in the operating system and it initializes it. It is usually located in EEPROM of the system. After the restarting of the computer system , all the loaded data gets transferred into the RAM(Random access memory).

   printf("Enter till where we want to find prime number: ");

   scanf("%d", &n);

   for(i=2; i<=n; i++)

   {

       prime = 1;  

       for(j=2; j<=i/2; j++)

       {

           if(i%j==0)

           {

               prime = 0;

       }

       if(prime==1)

       {

           printf("%d, ", i);

       }

   }

   return 0;

Explanation:

A number  which is divisible by 1 and itself is called prime number. Here in the program we start by taking number from 1 to n , where n is the last number till which we are required to find prime numbers. Then we start the loop by taking two for loops one for running the numbers from 1 to n and the inner for loop to check whether the number is divisible other than 1 and itself. We take the current number as prime =1. If the number is still not divisible by number other than 1 and itself we consider that number to be prime and print it.
