Answer:

a. ArrayList values = new ArrayList();

Correct way: ArrayList<Type> values = new ArrayList<>();

b. ArrayList values = new ArrayList();

Correct way: ArrayList<Type> values = new ArrayList<>();

c. ArrayList values = new ArrayList;

Correct way: ArrayList<Type> values = new ArrayList<>();

d. ArrayList values = new ArrayList();

for (int i = 1; i <= 10; i++) {

values.set(i - 1, i * i);

}

Correct way:

ArrayList<Integer> values = new ArrayList<>();

for (int i = 1; i <= 10; i++) {

*At this point size of the array is 0*

values.set(i - 1, i * i);

* "set()" method is used to set an element in an ArrayList object at the specified index and in this line is wrong bcz u have no objects added in your ArrayList. *

}

e. ArrayList values; --> You have to initialize the ArrayList

for (int i = 1; i <= 10; i++) {

values.add(i * i); }

Correct way:

ArrayList<Integer> values = new ArrayList<>();

for (int i = 1; i <= 10; i++) {

values.add(i * i); }

A user logs in to a virtual world and creates an animated character representing themselves, which they then use to move through

Romashka [77]

A type of animated character that represents a user in the virtual world, which is used to move throughout the world and interact with other characters and objects is called an <u>avatar</u>.

<h3>What is an avatar?</h3>

An avatar can be defined as a type of animated character that is designed and developed by a software developer to represent a user or player in the virtual world, which is used to move throughout the world and interact with other characters and objects.

In gaming technology and software development, an avatar is typically used to denote a user's (player's) character in the gaming world, virtual world or computer-simulated environment, either in two-dimensional (2D) or three-dimensional (3D).

One subtask in the game is to roll the dice. explain why is roll the dice an abstraction.

LUCKY_DIMON [66]

Answer:

A game is built from a combination of sub-tasks in order to provide the best experience to the user and make sure that the interface is comprises of only the results of the ongoing sub-tasks to provide a higher degree of data abstraction.

Data abstraction refers to the process of representing the essential information without including the background details. Rolling a dice is preferred to be a sub-task so that the user only gets to know about the result of the roll and does not have to wait for or anticipate the result. Moreover, a game may consist of n number of sub-tasks so it is not a good idea to include them in the main framework and are preferred to be abstracted.

Write the following function without using the C++ string class or any functions in the standard library, including strlen(). Yo

dolphi86 [110]

Answer:

The function in C++ is as follows

int chkInd(string str1, string str2){

int lenstr1=0;

while(str1[lenstr1] != '\0'){ lenstr1++; }

int index = 0; int retIndex=0;

for(int i=lenstr1-1;i>=0; i--){

while (str2[index] != '\0'){

if (str1[i] == str2[index]){

retIndex=1;

break; }

else{ retIndex=0; }

index++; }

if (retIndex == 0){ return i; }else{return -1;}}

}

Explanation:

This defines the function

int chkInd(string str1, string str2){

First, the length of str1 is initialized to 0

int lenstr1=0;

The following loop then calculates the length of str1

while(str1[lenstr1] != '\0'){ lenstr1++; }

This initializes the current index and the returned index to 0

int index = 0; int retIndex=0;

This iterates through str1

for(int i=lenstr1-1;i>=0; i--){

This loop is repeated while there are characters in str2

while (str2[index] != '\0'){

If current element of str2 and str1 are the same

if (str1[i] == str2[index]){

Set the returned index to 1

retIndex=1;

Then exit the loop

break; }

If otherwise, set the returned index to 0

else{ retIndex=0; }

Increase index by 1

index++; }

This returns the calculated returned index; if no matching is found, it returns -1

if (retIndex == 0){ return i; }else{return -1;}}

}
