Write the sequence of MOV instructions that exchange the upper and lower words i

Question

Write the sequence of MOV instructions that exchange the upper and lower words in the double word variable named three Show the order of individual bytes in memory (lowest to highest)for the following doubleword variable val 1 DWORD 89754321 Which flag is set when the result of a signed arthimatic operation is either too large or too small to fit imto the destination Which flag is set when an arithmetic or logical operation generates a negative result? Convert the hex number 2B9H to binar%/and decimal Add F34H+5D6H Implement the following arithmetic expression in assembly language- EAX = -val2 +7-val3+valL Assume that val1. val2, and val3 are 32-bk intern variables. What is the decimal representation of each of the following signed binary numbers 00101010,11001100 Write a program with a loop and indexed addressing that exchanged every pairsof values in an arras with an even number of elements. Therefore, item I will exchange with item i+1. and item i+2 will exchange with item i+3, and so on. Write a program that uses a loop to copy all the elements from an unsigned word (16 bit) array,into an unsigncd doubleivord (32 _Bjt)array

Explanation / Answer

Exchanging the pairs of array value

#include <stdio.h>
#define MAX 100
int main()
{
    int arr[MAX],n,i;
    int temp;
    
    printf("Enter total number of elements: ");
    scanf("%d",&n);
    
    //value of n must be even
    if(n%2 !=0)
    {
        printf("Total number of elements should be EVEN.");
        return 1;
    }
    //read array elements
    printf("Enter array elements: ");
    for(i=0;i < n;i++)
    {
        printf("Enter element %d:",i+1);
        scanf("%d",&arr[i]);
    }
    //swap adjacent elements
    for(i=0;i < n;i+=2)
    {
        temp    = arr[i];
        arr[i] = arr[i+1];
        arr[i+1]= temp;
    }
    
    printf(" Array elements after swapping adjacent elements: ");
    for(i=0;i < n;i++)
    {
        printf("%d ",arr[i]);
    }
    return;
}

Summing the Gaps between Array Values

#include <stdio.h>
#define MAX 100
int main()
{
    int arr[MAX],n,i;
    int temp;
   int sum=0;
    printf("Enter total number of elements: ");
    scanf("%d",&n);
    
   
    //read array elements
    printf("Enter array elements: ");
    for(i=0;i < n;i++)
    {
        printf("Enter element %d:",i+1);
        scanf("%d",&arr[i]);
    }
    
    for(i=0;i < n-1;i++)
    {
   sum+=(arr[i+1]-arr[i]);
    }
    printf("total difference between array elements %d",sum);
    return;
}
