Answer:

global

Explanation:

Its the global variable, and its scope is the whole program. And hence, a global variable is available throughout the program. And you need to know that a local variable has its scope in the block where it has been declared. Its scope is that block or the function or the loop only. And if you want it to have a global scope, then you will have to declare it as a global variable.

Write the definition of the function inputArray that prompts the user to input 20 numbers and stores the numbers into alpha. Wri

Alina [70]

Answer:

In Java:

public static int[] inputArray(){

Scanner input = new Scanner(System.in);

int[] alpha = new int[20];

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

alpha[i] = input.nextInt();

}

return alpha;}

public static int[] doubleArray(int [] alpha){

int[] beta = new int[20];

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

beta[i] = 2 * alpha[i];

}

return beta;

}

public static int[] copyAlphaBeta(int [] alpha, int [] beta){

int [] AlphaBeta = new int[10];

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

AlphaBeta[i] = alpha[i];

}

int count = 5;

for(int i = 15;i<20;i++){

AlphaBeta[count] = beta[i];

count++;

}

return AlphaBeta;

}

public static void printArray(int [] alpha){

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

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

if((i+1)%15 == 0){

System.out.println(" ");

}

Explanation:

The inputArray is defined here

public static int[] inputArray(){

Scanner input = new Scanner(System.in);

This declares alpha array of 20 elements

int[] alpha = new int[20];

The following iteration gets input from the user into the array

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

alpha[i] = input.nextInt();

}

This returns the alpha array

return alpha;}

The doubleArray is defined here. It takes the alpha array as its input parameter

public static int[] doubleArray(int [] alpha){

This declares beta of 20 integers

int[] beta = new int[20];

This populates beta by 2 * alpha[i]

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

beta[i] = 2 * alpha[i];

}

This returns the alpha array

return beta;}

The copyAlphaBeta array is defines here

public static int[] copyAlphaBeta(int [] alpha, int [] beta){

This declares AlphaBeta as 10 elements

int [] AlphaBeta = new int[10];

This populates the first 5 elements of AlphaBeta with the first 5 of alpha

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

AlphaBeta[i] = alpha[i];

}

int count = 5;

This populates the last 5 elements of AlphaBeta with the last 5 of beta

for(int i = 15;i<20;i++){

AlphaBeta[count] = beta[i];

count++;

}

This returns the AlphaBeta array

return AlphaBeta;

}

The printArray is defined here. It takes the alpha array as its input parameter

public static void printArray(int [] alpha){

This iterates through alpha array

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

This prints each element of the array

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

A new line is started after the 15th element

if((i+1)%15 == 0){

System.out.println(" ");

}

}

Input 10 integers and display the following:

LekaFEV [45]

Answer:

// code in C++

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

int sum_even=0,sum_odd=0,eve_count=0,odd_count=0;

int largest=INT_MIN;

int smallest=INT_MAX;

int n;

cout<<"Enter 10 Integers:";

// read 10 Integers

for(int a=0;a<10;a++)

{

cin>>n;

// find largest

if(n>largest)

largest=n;

// find smallest

if(n<smallest)

smallest=n;

// if input is even

if(n%2==0)

{

// sum of even

sum_even+=n;

// even count

eve_count++;

}

else

{

// sum of odd

sum_odd+=n;

// odd count

odd_count++;

}

// print sum of even

cout<<"Sum of all even numbers is: "<<sum_even<<endl;

// print sum of odd

cout<<"Sum of all odd numbers is: "<<sum_odd<<endl;

// print largest

cout<<"largest Integer is: "<<largest<<endl;

// print smallest

cout<<"smallest Integer is: "<<smallest<<endl;

// print even count

cout<<"count of even number is: "<<eve_count<<endl;

// print odd cout

cout<<"count of odd number is: "<<odd_count<<endl;

return 0;

}

Explanation:

Read an integer from user.If the input is greater that largest then update the largest.If the input is smaller than smallest then update the smallest.Then check if input is even then add it to sum_even and increment the eve_count.If the input is odd then add it to sum_odd and increment the odd_count.Repeat this for 10 inputs. Then print sum of all even inputs, sum of all odd inputs, largest among all, smallest among all, count of even inputs and count of odd inputs.

Output:

Enter 10 Integers:1 3 4 2 10 11 12 44 5 20

Sum of all even numbers is: 92

Sum of all odd numbers is: 20

largest Integer is: 44

smallest Integer is: 1

count of even number is: 6

count of odd number is: 4

Assume values 10, 20, 30, and 40 are entered in the cell range A1:A4. Cell A10 contains the formula: =A1+A2+A3+A4 and displays v

r-ruslan [8.4K]

Answer:

The formula and value to this question is "=A1+A3+A4+A5 with value 100"

Explanation:

The explanation of the given question as follows:

In question, it is defined that four cells that are "A1, A2, A3, and A4" contains value that are "10, 20, 30, and 40".
To add these values we use addition formula that is "=A1+A2+A3+A4". it will give value 100.
If the user inserts a new row that is "A2" and assigns a value in the cell that is "50" so, we use the above formula that adds values with these values we also use the value "100".
