Write a Java program in jGRASP that creates a 2D integer array of 5 rows and 20 columns, fills it with increasing integer values

Alex73 [517]

Answer:

As per the question we need to make 5 rowa and 2o columns, in this we have total element 100 so range should be 0 to 99, but we are suggested to keep range 0 to 59, so i have kept the elementns in the range, but if it was a typo in the question for range you do not need to reset the k with zero.

Explanation:

//create a new class TestArray

public class TestArray {

//define main method

public static void main(String[] args) {

//declare a 2D array of given size i.e. 5 rows and 20 columns

int arr[][] = new int[5][20];

//declare an integer variable k and initialize it with zero, this will used to initialize the array from 0 to 99

int k = 0;

//for loop for rows

for (int i = 0; i < 5; i++) {

//for loop for columns

for (int j = 0; j < 20; j++) {

//initialize arr with the current value of k

arr[i][j] = k;

//once k is 59 set it zero again as we are not going beyond 59

if(k == 59)

k = 0;

//increment value of k with 1

k++;

}

//print the element from the array one by one

//for loop for rows

for (int i = 0; i < 5; i++) {

//for loop for columns

for (int j = 0; j < 20; j++) {

//print the current element of array and an space with it

System.out.print(arr[i][j]+" ");

}

// move the cursor to new line

System.out.println();

}

Write a function with two parameters, prefix (a string, using the string class from ) and levels (an unsigned integer). The func

Allisa [31]

Answer:

Here is the program:

#include <iostream> //to use input output functions

#include <string> // to use functions to manipulate strings

using namespace std; //to identify objects cin cout

void function(string prefix, unsigned int levels){ // function that takes two parameters, a string, using the string class and levels an unsigned integer

if (levels == 0) { //if number of levels is equal to 0

cout << prefix << endl; //displays the value of prefix

return; }

for (int i = 1; i <=9 ; i++){ //iterates 1 through 9 times

string sections = (levels == 1 ? "" : "."); //if the number of levels is equal to 1 then empty space in sections variable otherwise stores a dot

string output = prefix + std::to_string(i) + sections; // displays the string prefix followed by the section numbers. Here to_string is used to convert integer to string

function(output, levels - 1); } } //calls function by passing the resultant string and levels-1 recursively to print the string prefix followed by section numbers

int main() { // start of main function

int level = 2; //determines the number of levels

function("BOX", level); } //calls function by passing the string prefix and level value

Explanation:

The program has a function named function() that takes two parameters, prefix (a string, using the string class from ) and levels (an unsigned integer). The function prints the string prefix followed by "section numbers" of the form 1.1., 1.2., 1.3., and so on. The levels argument determines how many levels the section numbers have. If the value of levels is 0 means there is 0 level then the value of prefix is printed. The for loop iterates '1' through '9' times for number of digits in each level. If the number of levels is 1 then space is printed otherwise a dot is printed. The function() calls itself recursively to print the prefix string followed by section numbers.

Let us suppose that prefix = "BOX" and level = 1

If level = 1 then the loop for (int i = 1; i <=9 ; i++) works as follows:

At first iteration:

i = 1

i <=9 is true because value of i is 1

string sections = (levels == 1 ? "" : "."); this statement checks if the levels is equal to 1. It is true so empty space is stored in sections variable so,

sections = ""

Next, string output = prefix + std::to_string(i) + sections; statement has prefix i.e BOX plus value of i which is 1 and this int value is converted to string by to_string() method plus sections has an empty space. So this statement becomes

string output = BOX + 1

So this concatenates BOX with 1 hence output becomes:

output = BOX1

At second iteration:

i = 2

i <=9 is true because value of i is 2

string sections = (levels == 1 ? "" : "."); is true so

sections = ""

Next, string output = prefix + std::to_string(i) + sections; statement becomes

string output = BOX + 2

So this concatenates BOX with 1 hence output becomes:

output = BOX2

At third iteration:

i = 3

i <=9 is true because value of i is 3

string sections = (levels == 1 ? "" : "."); is true so

sections = ""

Next, string output = prefix + std::to_string(i) + sections; statement becomes

string output = BOX + 3

So this concatenates BOX with 1 hence output becomes:

output = BOX3

Now at each iteration the prefix string BOX is concatenated and printed along with the value of i. So at last iteration:

At last iteration:

i = 9

i ==9 is true because value of i is 9

string sections = (levels == 1 ? "" : "."); is true so

sections = ""

Next, string output = prefix + std::to_string(i) + sections; statement becomes

string output = BOX + 9

So this concatenates BOX with 1 hence output becomes:

output = BOX9

After this the loop breaks at i = 10 because the condition i<=9 becomes false. So the output of the entire program is:

BOX1 BOX2 BOX3 BOX4 BOX5 BOX6 BOX7 BOX8 BOX9

The program along with the output is attached.

What is the computer software? Does a hardware can work without software?

mr Goodwill [35]

Answer:

Hope this helped!

Explanation:

A computer software is anything that lets you work with computers what happens inside it, and hard ware is the actual computer and its parts, so no a computer hardware CANNOT work without a software.
