Brut [27]

Answer:

oid changeCase (char char_array[], int array_size ) {

__asm{

mov eax, char_array;

mov edi, 0;

readArray:

cmp edi, array_size;

jge exit;

mov ebx, edi;

shl ebx, 2;

mov cl, [eax + ebx];

check:

//working on it

cmp cl, 0x41;

jl next_indx;

cmp cl, 0x7A;

jg next_indx;

cmp cl, 'a';

jl convert_down;

jge convert_up;

convert_down:

or cl, 0x20; //make it lowercase

jmp write;

convert_up:

and cl, 0x20;

jmp write;

write:

mov byte ptr [eax + ebx], cl

next_indx:

inc edi;

exit:

cmp edi, array_size;

jl readArray;

mov char_array, eax;

}

Explanation:

Move char_array to eax as it is base image .
Use ebx as offset .
Use ecx as the storage register .
check if cl is <= than ASCII value 65 (A) .

Suppose we have two String objects and treat the characters in each string from beginning to end in the following way: With one

Simora [160]

Answer:

If all the character pairs match after processing both strings, one string in stack and the other in queue, then this means one string is the reverse of the other.

Explanation:

Lets take an example of two strings abc and cba which are reverse of each other.

string1 = abc

string2 = cba

Now push the characters of string1 in stack. Stack is a LIFO (last in first out) data structure which means the character pushed in the last in stack is popped first.

Push abc each character on a stack in the following order.

c

b

a

Now add each character of string2 in queue. Queue is a FIFO (first in first out) data structure which means the character inserted first is removed first.

Insert cba each character on a stack in the following order.

a b c

First c is added to queue then b and then a.

Now lets pop one character from the stack and remove one character from queue and compare each pair of characters of both the strings to each other.

First from stack c is popped as per LIFO and c is removed from queue as per FIFO. Then these two characters are compared. They both match

c=c. Next b is popped from stack and b is removed from queue and these characters match too. At the end a is popped from the stack and a is removed from queue and they both are compared. They too match which shows that string1 and string2 which are reverse of each other are matched.

Write a program to read a list of exam scores given as integer percentages in the range 0-100. Display the total number of grade

Tju [1.3M]

Answer:

import java.util.Scanner;

public class Program

{

public static void main(String [] Args)

{

int totalAGrades = 0, totalBGrades = 0, totalCGrades = 0, totalDGrades = 0, totalFGrades = 0, counter=0,maximum = 0, minimum = 9999, num, total = 0,smallest = 0,largest = 0;

Scanner in = new Scanner(System.in);

System.out.println("Enter exam percentage: ");

System.out.println("Enter a negative examScore: ");

int examScore = in.nextInt();

while(examScore > 0)

{

counter++;

if(examScore < 0){

break;}

else if(examScore > maximum){

maximum = examScore;}

else if(examScore < minimum) {

minimum = examScore;}

total = total + examScore;

if(examScore <= 50 && examScore>0)

smallest = examScore;

if(examScore > 90 && examScore <=100)

largest = examScore;

if(examScore>=90 && examScore<=100)

totalAGrades++;

else if(examScore>=80 && examScore<=89)

totalBGrades++;

else if(examScore>=70 && examScore<=79)

totalCGrades++;

else if(examScore>=60 && examScore<=69)

totalDGrades++;

else if(examScore>=0 && examScore<=59)

totalFGrades++;

examScore = in.nextInt();

}

System.out.println("Total number of scores is = " + counter );

System.out.println("Total Number of each Letter grade : " + counter);

System.out.println("Percentage of total for each letter grade : ");

System.out.println("Total number of A grades = "+ totalAGrades);

System.out.println("Total number of B grades = "+ totalBGrades);

System.out.println("Total number of C grades = "+ totalCGrades);

System.out.println("Total number of D grades = "+ totalDGrades);

System.out.println("Total number of F grades = "+ totalFGrades);

System.out.println("Lowest exam Score is :"+smallest);

System.out.println("Highest exam Score is :"+largest);

System.out.println("Average exam Score = "+ (total / counter));

}

Explanation:

Get the exam information from user as input and run a while loop until examScore is greater than zero.
Use conditional statement to check the scores of students and increment the relevant grade accordingly.
Finally display all the information including grades and scores.

A document with a horizontal dimension greater than its vertical dimension is in _____ orientation.

Juli2301 [7.4K]

The answer is Portrait, or Option Choice C.

Diagonal can be relative to any shape

Sideways can be relative to any shape

Portrait is usually more vertical than horizontal because it is used to depict a person, usually stopping at the bottom of the torso

By process of elimination, Landscape is the answer. Also, its because Landscape is usually used to depict the Land scape. What a surprise. And as you know, their is only so far you can paint vertically , but there is much more to paint horizontally. Making the canvas more horizontal than vertical.<span />
