A variable like userNum can store a value like an integer. Extend the given program to print userNum values as indicated.(1) Out

dimulka [17.4K]

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

int userNum;

Scanner input = new Scanner(System.in);

System.out.print("Enter integer: ");

userNum = input.nextInt();

System.out.println("You entered "+userNum);

System.out.println(userNum+" squared is "+(userNum*userNum));

System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

int userNum2;

System.out.print("Enter another integer: ");

userNum2 = input.nextInt();

int sum= userNum + userNum2; int product = userNum2 * userNum;

System.out.println(userNum+" + "+userNum2+" = "+sum);

System.out.println(userNum+" * "+userNum2+" = "+product); } }

Explanation:

This declares userNum

int userNum;

Scanner input = new Scanner(System.in);

This prompts the user for input

System.out.print("Enter integer: ");

This gets user input from the user

userNum = input.nextInt();

Number (1) is implemented here

System.out.println("You entered "+userNum);

Number (2) is implemented here

System.out.println(userNum+" squared is "+(userNum*userNum));

System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

This declares another variable userNum2

int userNum2;

This prompts the user for another input

System.out.print("Enter another integer: ");

This gets user input from the user

userNum2 = input.nextInt();

This calculates the sum and the product

int sum= userNum + userNum2; int product = userNum2 * userNum;

Number (3) is implemented here

System.out.println(userNum+" + "+userNum2+" = "+sum);

System.out.println(userNum+" * "+userNum2+" = "+product);

Write code that prints: Ready! firstNumber ... 2 1 Run!

motikmotik

Answer:

The program to this question can be defined as follows:

Program:

num=int(input("Enter any number: ")) #defining variable num, that take value from user

val=0; #defining variable val

for i in range(num): #defining loop to calculate value in decreasing order

val=num-i; #holding value in variable

print(val) #print value

Output:

Enter any number: 3

3

2

1

Explanation:

In the above-given code, a variable "num" is declared, that uses input function to take value from the user end, in the next line a "val" variable is defined, that calculates values and print it in decreasing order.

In the next step, a for loop is declared, inside the loop a "val" variable uses num and loop variable "i" to calculate the value in decreasing order.
In the last print method is used that prints "val" variable value.

Which control chart would you use to track rejections in a maintenance projeg when bug arrival pattern is not constant?

Mkey [24]

Answer:

P chart is the control chart that is used to monitor the rejection or acceptance whenever the bug arrival in pattern is not constant.

Explanation:

In case of only two possible outcomes, such as yes or no, accept or reject, P chart is used as control chart to track rejections. It is used to track rejections whenever the pattern of rejection is not constant. In this type of charts we collect the information from last few days to analyze and predict the next data to track rejections.

For example:

If we want to know that, in admission department of the university, how many students arrives to take admission in university, does not meet the qualification criteria each week. In this case there are only two options available either they meet criteria or not. In this case we use P chart with the help of previous week data to analyze the no. of students who are meeting qualification criteria in this week.
