Answer:

Written in Python

for count in range(88, 42,-2):

print(count,end=' ')

Explanation:

The programming language is not stated.

However, I used python to answer the question.

First, we need to loop from 88 to 44 with a difference of -2 in each term.

This is implemented as

for count in range(88, 42,-2):

Which means to start at 88 and ends at 42 - (-2) which is 44 with an increment of -2

Next, is to print the current iterating value;

This is implemented using print(count)

However, since all values are to be printed on a line, there's a need t modify the statement as: print(count,end=' ')

Explain how technology is related to human needs and wants?

Burka [1]

Technology is what makes up the world. It makes life easier, and technology has been around since humans were first evolved. Our questionative behavior is what separates us from other animals. Our need for more is what runs humankind. Using technology to gain more, our kind becomes smarter, which is why we dominate other species. Technology millions of years ago could be a club to kill prey for food, and now, it is how we order essentials. Technology is an easier way to gain something, and since technology is all over the world, humankind will always have their need and want for more.

Write a method called all Less that accepts two arrays of integers and returns true if each element in the first array is less t

GaryK [48]

Answer:

The program to this question can be given as:

Program:

#include<iostream> //header file

using namespace std; //using name space

bool allLess (int arr1[], int arr2[]) //defining method allLess

{

int a,b; //define variable

a= *(&arr1 + 1) - arr1; //hold length of arr1

b= *(&arr2 + 1) - arr2; //hold length of arr2

if(a!=b) //checking condition

{

return 1; //return value

}

for(int i=0; i<a; i++) //loop

{

if( arr1[i]>=arr2[i]) //checking condition

{

return 1; //return value

}

return 0; //return value

}

int main() //define main method.

{

int arr1[]={1,2,3,4,5}; //define array arr1 and assign value.

int arr2[]={4,5,6,7,8}; //define array arr2 and assign value.

cout<< allLess(arr1,arr2); //function calling

return 0;

}

Output:

Explanation:

The Explanation of the C++ language program can be given as follows:

In the above program firstly we include the header file. Then a method is defined that is "allLess" this method accepts two arrays that are "arr1 and arr2". This function returns a boolean value that is true or false.
Inside a function, we define a conditional statement and a loop in the if block we check the length of the arr1 array variable is not equal to arr2 array length. if this condition is true it will return false.
In the loop, we define another if block in this block we check that if arr1 array elements are grater then equal to arr2 array element if this condition is true it will return false. At the end of both if block and loop the function will return a value that is "true".
In the main method, we define two arrays and pass to the function and use (cout function) for print return value.

A program is considered portable if it . . . can be rewritten in a different programming language without losing its meaning. ca

Semenov [28]

Answer:

Can be executed on multiple platforms.

Explanation:

A program is portable if it is not platform dependent. In other words, if the program is not tightly coupled to a particular platform, then it is said to be portable. Portable programs can run on multiple platforms without having to do much work. By platform, we essentially mean the operating system and hardware configuration of the machine's CPU.

Examples of portable programs are those written in;

i. Java

ii. C++

iii. C

A computer understand..............codes.<br>

KiRa [710]

Answer:Computers only understand machine code - they do not understand high-level language code. Any high-level programming language code has to be converted to executable code. Executable code is also known as machine code which is a combination of binary code 0s and 1s.

You're a ticket agent for a commercial airline and responsible for checking the identification for each passenger before issuing

algol13

Answer:

Follows are the code to this question:

import java.util.*;//import package for user input

public class Main //defining class

{

public static void main(String[] as)//main method

{

boolean x,y,z;//defining boolean variable

Scanner ox= new Scanner(System.in);//create Scanner class object for user input

System.out.println("input value: "); //print message

x=ox.nextBoolean();//input value

y=ox.nextBoolean();//input value

z=ox.nextBoolean();//input value

System.out.println("Output: ");//print message

System.out.println(x || (y &&z));//use print method to check value and print its value

}

Output:

input value:

true

false

Output:

true

input value:

false

true

Output:

true

input value:

false

Output:

false

Explanation:

In the given code, inside the class three boolean variable "x,y, and z" is declared, that uses the scanner class for input the value from the user end, and in the next print, the method is declared, that uses " OR and AND" gate for calculating the input value and print its value.

In the AND gate, when both conditions are true. it will print the value true, and in the OR gate, when one of the conditions is true, it will print the value true.
