25 SQUARES

How this is calculated?

The size of the squares doesn't matter, since the number of squares will be the same.
We have a row of 5 squares: and on top of this you stack 5 more squares.

Doing this for a total of 5 times so that we have 5 rows with 5 squares each.

So we have 5 + 5 + 5 + 5 + 5 = 25 squares.

What is an array?

An array is a data structure that holds similar, related data.
Before an array can be used, it must be declared. To declare an array a programmer gives it at least two properties:

an identifier
a size - the number of elements it will hold

Implement a function inValues() that asks the user to input a set of nonzero floating-point values. When the user enters a value

elena-s [515]

Answer:

Explanation:

The following is written in Python and uses exception handling to do exactly as requested. It then goes adding all of the integer values to an array called num_list and finally adding them all together when the function ends.

def in_values():

num_list = []

while True:

try:

num = input("Input non-zero floating point: ")

num = int(num)

if num == 0:

break

else:

num_list.append(num)

except ValueError:

print("No valid integer! Please try again ...")

try:

num = input("Input non-zero floating point: ")

num = int(num)

break

except ValueError:

break

sum = 0

for number in num_list:

sum += number

return sum

John wants to know the amount of ram memory installed on his computer. in which category of the windows 7 control panel can this

Verizon [17]

John can find the amount of Random Access Memory (RAM) memory installed on his computer with the Windows 7 under the category “<u>System and Security</u>” in the Control Panel.

To know the total amount of installed RAM through Control Panel in the computer with Windows 7, John should follow the steps as:

Click the Windows key

Type Control Panel

Click the category named “System and Security”

Now under “System”, click “View amount of RAM and processor speed”

“Device Specifications” section displays the amount of installed RAM in John’s computer

Thus, above are the steps by which John’s can find the amount of installed RAM in his Windows 7 computer’s Control Panel.

What is Random Access Memory (RAM)?

RAM is the temporary memory in computers that stores the data currently being used by the processor.

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);
