This simple code should be able to get the string starting from the 7th character until the 18th

character and copy it to DUP that we created.. please help me to complete this code by using loop..

org 100h

mov ah,ds:[abc]

loop1 :

xor cx,cx[7] ; cx-register is the counter, set to 0

nop ; Whatever you wanna do goes here, should not change cx

inc cx ; Increment

cmp cx,18 ; Compare cx to the limit

jle loop1 ; Loop while less or equal

ret

abc DB 'hellokjgknvkgnkvnasdkfnsdk\0'

def DB 100 DUP(?)

str DB 7

fin DB 18

I have created two classes..

one of them has the main class, which is the AverageTest..

the other one has the Average method, which is the Average Class

I'm writing some numbers in the AverageTest class by using new Objects to call the

Average method.. by taking an int parameter in the main class. I'd like to read those numbers

written as parameters and then by calling the Average Method the calculation starts and prints out the

average of the numbers ..

ActivityRoom activityroom = new ActivityRoom(0, 0, 0); //this is a new object created

activityroom.acceptAPerson(55); //the numbers are read from the parameters as shown

activityroom.acceptAPerson(45);

activityroom.acceptAPerson(35);

activityroom.calculateAverageAgeOfPeople();

the acceptAPerson is a method in the Average class..

please help ! I tried everything

In how many ways can a teacher distribute 12 different science books among 16 students if a) no student gets more than one book,

b) the oldest student gets two books but no other student gets more than one book?

How many solutions are there to the equation

x1 + x2 + x3 + x4 + x5 + x6 = 29

, where xi, i = 1, 2, 3, , 4, 5, 6, is a nonnegative integer such that

a) xi ≥ 2 for i = 1,2,3,4,5,6?

b) x1 ≥1, x2 ≥2, x3 ≥3, x4 ≥4, x5 >5 and x6 ≥6?

c) x1 ≤ 5? (HINT: consider all cases and subtract those cases where x1 > 5)

d) x1 < 8 and x2 > 8? (HINT: again consider all possible values of x1, and subtract those cases with x1 ≥ 8)
