Question

Assembly Language:

5) What is the output of the following assembly code segment? How would the code be written in a higher-level language?

       mov x, 25
       mov y, 3
       mov ax, x
       cmp ax, y
       je One
       cmp y, 0
       jnl Two
       jmp Next
One: imul y
        jmp Next
Two: mov Num, 10
        imul Num
Next: call PutDec

Explanation / Answer

Question 5)

Output: +250

High level language Code(Java):

class Problem5{
   public static void main(String a[])
   {
       int x=25;//mov x, 25
       int y=3;//mov y, 3
       int ax=x;//mov ax, x       ax is accumulator
       if(ax==y)//ax is equal to y
       {
           //One label code
           //al is lower 8 bits in ax.Here ax=25=al
           int al=ax;
           ax = al*y;//imul y
           //Next label code
           System.out.println(ax);//call PutDec
       }
       else if(y>=0)//y is not less than 0
       {
           //Two label code
           int Num = 10;//mov Num, 10
           int al=ax;//al is lower 8 bits in ax.Here ax=25=al
           ax = al*Num;//imul Num
           //Next label code
           System.out.println(ax);//call PutDec
       }
       else
       {
           //Next label code
           System.out.println(ax);//call PutDec
       }
      
   }
}

Question 6)

Output: +25

High level language Code(Java):

class Problem6{
   public static void main(String a[])
   {
       int x=5;//mov x, 5
       int y=5;//mov y, 5
       int ax=x;//mov ax, x       ax is accumulator
       if(ax==y)//ax is equal to y
       {
           //One label code
           //al is lower 8 bits in ax.Here ax=5=al
           int al=ax;
           ax = al*y;//imul y
           //Next label code
           System.out.println(ax);//call PutDec
       }
       else if(y>=0)//y is not less than 0
       {
           //Two label code
           int Num = 10;//mov Num, 10
           int al=ax;//al is lower 8 bits in ax.Here ax=5=al
           ax = al*Num;//imul Num
           //Next label code
           System.out.println(ax);//call PutDec
       }
       else
       {
           //Next label code
           System.out.println(ax);//call PutDec
       }
      
   }
}
