Question
Chapter 3, Problem 13PE
Program Plan Intro
Finding sum
- Define the main function.
- Get the value of “n” from the user.
- Declare a variable “sum”.
- Loop from 1 through “n+1”.
- Get the numbers from the user and store it in a variable “num”.
- Calculate the value of sum by adding “sum” and “num” and store it in a variable “sum”.
- Print the value of “sum”.

Students have asked these similar questions
Input numbers from user and find sum of all those input numbers until user inputs zero. In
other means, loop should end when user enters 0. Finally, display the sum of all those
numbers entered by user.
6. Distance Traveled
The distance a vehicle travels can be calculated as follows:
distance = speed time
For example, if a train travels 40 miles per hour for 3 hours, the distance traveled is
120 miles.
Write a program that asks the user for the speed of a vehicle (in miles per hour) and how
many hours it has traveled. The program should then use a loop to display the distance the
vehicle has traveled for each hour of that time period. Here is an example of the output:
What is the speed of the vehicle in mph? 40
How many hours has it traveled? 3
Hour Distance Traveled
1
40
2
80
3
120
Input Validation: Do not accept a negative number for speed and do not accept any
value less than 1 for time traveled.
Basic while loop expression.
Write a while loop that prints userNum divided by 4 (integer division) until reaching 2 or less. Follow each number by a space. Example output for userNum = 160:40 10 2 Note: These activities may test code with different test values. This activity will perform four tests, with userNum = 160, then with userNum = 8, then with userNum = 0, then with userNum = -1. See "How to Use zyBooks".Also note: If the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "Program end never reached." The system doesn't print the test case that caused the reported message.

Random Number Guessing Game Write a program that generates a random number between 1 and 100 and asks the user to guess what the number is. If the user’s guess is higher than the random number, the program should display “Too high. Try again.” If the user’s guess is lower than the random number, the program should display “Too low. Try again.” The program should use a loop that repeats until the user correctly guesses the random number. Then the program should display “Congratulations. You figured out my number.”arrow_forwardThe distance a vehicle travels can be calculated as follows: Distance = Speed X TimeDesign a program that asks a user for the speed of a vehicle in miles per hour and how many hours it has travelled (Assume the two values are integers). Your program should then use a loop to display the distance the vehicle has traveled for each hour of that time period. (For example, entering 50 mph and 4 hours should produce output like: Hour 1: 50 miles, Hour 2: 100 miles, Hour 3: 150 miles, Hour 4: 200 miles. )arrow_forward
- Q2: Write a program that reads in a series of integer numbers, and determines how many positive odd numbers are among them. Numbers are read until a negative integer is given. Use DO-Loop with EXIT statement.arrow_forwardPYTHON PROGRAMMING ONLY. Please provide explanation as well. Thank you. Write a while loop that lets a user enter a number less than 10. If the number inputted exceeds 10, print an error and ask for the number again, in which a user may enter the same or a different number. When the user inputs a valid number, the number should be incremented by 5, and the result assigned to a variable named sum. This loop should continue to iterate as long as the sum totals less than 50. When sum exceeds 30, it should print "Almost there..." until it reaches or exceeds 50. Once it does, print out "your final sum is (replace with final sum)". For example, if the sum is currently 45 and the user inputs 4, the program will not enter the loop again since the new sum will be 54 and should then print "your final sum is 45".arrow_forward1. first ask the user to enter the number of students in the range of 1 to 10. 2. then the program asks the user to enter the number of tests (in the range of 1 to 5) 3. Then use a loop to collect the scores for those many tests for each student. The outer loop will iterate once for each student. The inner loop will iterate several times, once for each test. Each iteration of the inner loop will ask the user to enter the score for a test of a student.arrow_forward

- Part A: While Loop ProgramWrite a program that detects Fibonacci numbers. Prompt the user to input a positive integer. Upon input, the program will determine if the number is either a Fibonacci number or not. If a Fibonacci number, then the order of the number in the sequence must be output. If not a Fibonacci number, then the Fibonacci numbers above and below it (including their order in the sequence) must be output. Once it finishes, the program will prompt the user for a new number. The program will exit if the user enters a non-integer number or string (such as “quit”) instead of an integer. Use the sample output file, fib-seq-det.txt, to view a sample session For both the above problems, the first four numbers of the Fibonacci sequence are 0, 1, 1, and 2. Part A must use While loops only. Invalid (negative) numbers should be flagged and handled. Output should be like: Welcome to the Fibonacci Sequence Detector Please input a number for analysis >> 00 is a…arrow_forwardprogram using a while loop that lets the user enter a series of integers. The user should enter 10 values and the program will display the two largest numbers. You can only use a number once.arrow_forwardProblem 2: Safe Square Root Write a program to take the square root of a number typed in by the user. Your program should use a while-loop to ensure that the number they typed in is positive. If the number is negative, you should print out a warning “The number is negative. Try again.” and re-prompt the user to take a valid input. You can get the square root of a number n with Math.sqrt(n). Make sure you don't do this until the loop is done and you know for sure you've got a positive number. Sample input and output: Enter a number > -9 The number is negative. Try again. Enter a number > 9 The square root of 9 is 3.0 Enter a number > 2 The square root of 2 is 1.4142135623730951arrow_forward
