Human centered technology often recommends best practices to computer designers and manufacturers, ...............

Human-Computer Interaction is a study that particularly focuses more on the design of computer technology and the interaction between humans and computers. Since the 1980s when HCI surfaced, it has become a crucial tool in popularizing the idea that the interaction between a user and a computer should resemble a human-to-human, open-ended dialogue. When HCI is done well, a human-centered approach powers the creation of products that resonates more deeply with a certain audience. This will ultimately drive engagement and growth.

Display all the natural numbers from 1 to 100 that are exactly divisible by 3 and 7 using FOR … NEXT. Without using Mod
Tcecarenko [31]

Answer:

FOR i% = 1 TO 100

 IF ((i%\3) = i%/3) AND ((i%\7) = i%/7)  THEN

   PRINT i%

 END IF

NEXT i%

Explanation:

Of course using MOD would be cleaner, but another way to check if a number is integer divisable is to compare the outcome of an integer division to the outcome of a floating-point division. If they are equal, the division is an integer division.

The program outputs:

)Dynamically allocate an object of Banana, using the pointer variable daco.
zepelin [54]

Answer:

d) daco = new Banana;

Explanation:

Dynamically allocated variables have their memory allocated in the heap memory.We declare a dynamical variable like this:-

int *a=new int ;

It means a pointer a is created on the stack memory which hold the address of the block that hold the value of variable a in heap memory.

We already have the pointer daco. We just have to initialize with keyword new.

It will be like daco=new Banana; which matches the option d.
