Hi There was small mistake. It is working fine for me. When you run from command line - use LoopPattern, not looppatern

import java.util.Scanner;

public class Looppattern {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.println("Enter how man levels you need: ");

int levels = sc.nextInt();

System.out.println("\n---------------Pattern A-----------------\n");

for (int p = 1; p <= levels; p++) {

for (int k = 1; k <= p; k++) { // increasing each level printing

System.out.print(k);

}

System.out.println();

}

System.out.println("\n---------------Pattern B-----------------\n");

int r = levels;

for (int p = 1; p <= levels; p++) {

for (int k = 1; k <= r; k++) {

System.out.print(k);

}

r--; // decreasing levels

System.out.println();

}

System.out.println("\n---------------Pattern C-----------------\n");

for (int p = 1; p <= levels; p++) { // here incresing

for (int k = p; k > 0; k--) { // and here decreasing pattern to

System.out.print(k);

}

System.out.println();

r--; // decreasing levels

System.out.println();

Given: an int variable k, an int array current Members that has been declared and initialized, an int variable memberID that has

Alekssandra [29.7K]

Answer:

The c++ program is given below. Nothing is displayed as per the question.

#include <iostream>

using namespace std;

int main() {

// declaration and initialization of integer variables

int k, memberID = 12, nMembers=5;

bool isAMember;

// declaration and initialization of integer array

int currentMembers[] = {12, 34, 56, 78, 90};

for(k=0; k<nMembers; k++)

{

if(memberID == currentMembers[k])

{

// when member is found in the array, the loop is exited using break

isAMember = true;

break;

}

else

isAMember = false;

}

return 0;

}

Explanation:

The program begins with declaration and initialization of integer variables and followed by initialization of the array holding the id of all the members.

The Boolean variable is declared but not initialized.

int k, memberID = 12, nMembers=5;

bool isAMember;

int currentMembers[] = {12, 34, 56, 78, 90};

After this, the array holding the id of the members is searched for the given member id. This is done using a for loop and a if else statement inside the loop.

If the member id is present in the array, the variable isAMember is initialized to true otherwise it is assigned false.

When the variable isAMember is initialized to true, the break statement is used to exit from the loop.

for(k=0; k<nMembers; k++)

{

if(memberID == currentMembers[k])

{

isAMember = true;

break;

}

else

isAMember = false;

}

The break is used since other values of id in the array will not match the given member id and the variable, isAMember will be initialized to false even if the given member id is present in the array. Hence, it is mandatory to exit the loop once the given member id is found in the array.

This program can be tested for different values of the id of the members and different sizes of the array.

In a program, you need to store the identification numbers of 10 employees (as integers) and their weekly gross pay (as double v

dedylja [7]

Answer:

The code to the given question can be given as:

Code:

2 arrays that used to store 10 employee identification number and grosspay amount in parallel and its data-type is int and double.

int Employee_id[10]; //array that store integer value

double Weekly_Gross_Pay[10]; //array that store double value

Define loop for print the details of employees’ identification number and weekly gross pay.

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

{

cout <<Employee_id[i] <<" " << Weekly_Gross_Pay[i] << endl;

}

Explanation:

The explanation of the above code can be given as:

In Code (1) we declare two array that's data-type is integer and double. In Employee_id array it store the integer values and Weekly_Gross_Pay it store the double value.

In Code(2) It is used to print the value of array. In that code, we used for a loop because of its entry control loop and we know the size of the array. In this loop, we declare a variable (i) and initialized the value 0 and check the condition(i)less than 1 and increment of i. It prints all the 10 values.

(a) Correlated.

Explanation:

Correlated subquery :These sub queries reference columns from outer table or uses values from outer query.These sub queries are processed atleast once for every row processed.So because of this reason correlated sub queries can be slow.Since the query in the question also uses value from the outer query so it is a correlated query.
