Answer: You need a temporary variable to hold the value 3

Explanation:

So, aList[0] is 3 and aList[1] is 19, if it will be as it is you litteraly say to the compiler to change aList[0] to aList[1] at this moment aList[0] is 19 and aList[1] also is 19 and if you try to change aList[1] to aList[0] it will not change its value because they are the same.

You need temp variable to keep one of the values.

Answer:

Begin the statement with the proper keyword to start the loop

Explanation:

Given

The code segment

Required

Fix the code

The first line of the code segment is meant to be a for loop, but it does follow the right syntax.

This is so because the for keyword is missing.

The first line should be corrected and replaced with:

for count in range(80):

Hence, option (b) is correct

Write a program that first gets a list of integers from input. Then, get another value from the input, and output all integers l

jonny [76]

Answer:

The c++ program for the given scenario is given below.

#include <iostream>

using namespace std;

int main() {

int len=20, arr[len], data;

// initialize all elements of the array to 0

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

{

arr[i] = 0;

}

cout<<"This program outputs all the numbers less than or equal to the given number."<<endl;

cout<<"Enter the list of numbers. Enter 0 to stop entering the numbers. "<<endl;

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

{

cin>>arr[i];

// 0 indicates user wishes to stop entering values

if(arr[i] == 0)

break;

else

continue;

}

// number from which the list is to be compared

cout<<"Enter the number to be compared."<<endl;

cin>>data;

cout<<"The values less than or equal to the number "<<data<<" are "<<endl;

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

{

// 0 indicates the end of the list entered by the user

if(arr[i]==0)

break;

if(arr[i] <= data)

cout<<arr[i]<<endl;

}

return 0;

}

OUTPUT

This program outputs all the numbers less than or equal to the given number.

Enter the list of numbers. Enter 0 to stop entering the numbers.

Enter the number to be compared.

The values less than or equal to the number 59 are

Explanation:

This program takes input only from the user and makes no assumptions.

The list of numbers entered by the user are stored in an array. If the user input is less than the size of the array, the remaining elements are set to 0.

While taking input from the user, if any element of the array is found to be 0, the loop is discontinued.

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

{

cin>>arr[i];

if(arr[i] == 0)

break;

else

continue;

}

Same test is applied when all the numbers less than the given number are displayed.

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

{

if(arr[i]==0)

break;

if(arr[i] <= data)

cout<<arr[i]<<endl;

}

The above program takes into account all the specifications in the given question.

Write a Python function to determine the volume of material remaining after the hole is drilled. The function should take as inp

Andru [333]

Answer:

height = int(input ("Enter height : ") )

print (height)

width = int( input("Enter length : ") )

print (width)

half_width =width/2

half_height=height/2

while 0==0:

radius = float( input("Enter radius : ") )

print (radius)

if radius<half_width and radius <half_height:

break

def remainingVolume(height,width,radius):

vol_box=height*width*width

print (vol_box)

vol_hole=3.14178*radius*radius*height

print (vol_hole)

remaining_vol=vol_box-vol_hole

print ("Remaining volume is ",remaining_vol)

remainingVolume(height,width,radius);

Explanation:

Take input from user for height ,width and radius. To find volume of box formula is $vol=height* width*length\\$

Let's assume width and length is same so

length= width

Using this formula of box volume find box volume.Now find volume of hole.

Consider hole as small cylinder, find volume of cylinder and subtract from volume of box to get remaining volume of box after hole.

$vol_of_cyl=\pi radius^{2} height$
