You will write a program that calculates gas milage, also known as fuel economy. The program will use a while loop to repeatedly ask the user for the number of miles driven and gallons of gas used at their last fill up. On each iteration of the loop, your program will calculate the mileage for each fill up. The user will be able to exit the loop by pressing the enter key. After the user exits the loop, the program will print the cumulative gas mileage, by dividing the cumulative number of miles by the cumulative number of gallons. The floating point output should be printed to one decimal place of precision. Here is an example of how the program should work: Your Personal Fuel Economy Number of miles traveled (or enter to exit): 380 Number of gallons needed: 12 Mileage this tank: 31.7 Number of miles traveled (or enter to exit): 235 Number of gallons needed:9 Mileage this tank: 26.1 Number of miles traveled (or enter to exit): Average mileage: 29.3

Concept explainers

Types of Loop

Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.

Loops

Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.

While Loop

Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.

Question

**Gas Mileage Calculation Program**

You will write a program that calculates gas mileage, also known as fuel economy. The program will use a while loop to repeatedly ask the user for the number of miles driven and gallons of gas used at their last fill-up. On each iteration of the loop, your program will calculate the mileage for each fill-up. The user will be able to exit the loop by pressing the enter key. After the user exits the loop, the program will print the cumulative gas mileage by dividing the cumulative number of miles by the cumulative number of gallons. The floating-point output should be printed to one decimal place of precision.

**Example Program Output:**

```
Your Personal Fuel Economy
Number of miles traveled (or enter to exit): 380
Number of gallons needed: 12
Mileage this tank: 31.7
Number of miles traveled (or enter to exit): 235
Number of gallons needed: 9
Mileage this tank: 26.1
Number of miles traveled (or enter to exit):
Average mileage: 29.3
```

This example demonstrates how users input values for miles and gallons, receive feedback on their current mileage, and finally obtain an average mileage once the program concludes.

This program requires the student to create a programming loop. The program's loop with loop between 5 and 50 times. Each loop will represent one week of the user eating and buying food. Each week the user will input the amount he or she spent on food. If the person spends more than $250 then the program will output "You are going to get fat." If the person spends less than $50.55 then the program will output "You are going to starve." After the final loop the program will display the lowest amount spent on any one week along with the most spent on any one week.

Design a program that uses nested loops to collect data and calculate the average rainfall over a period of years. The program should first ask for the number of years. The outer loop will iterate once for each year. The inner loop will iterate twelve times, once for each month. Each iteration of the inner loop will ask the user for the inches of rainfall for that month. After all iterations, the program should display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period. Modularize the program.

In this lab, you write a while loop that uses a sentinel value to control a loop in a Python program. You also write the statements that make up the body of the loop. The source code file already contains the necessary assignment and output statements. Each theater patron enters a value from 0 to 4 indicating the number of stars that the patron awards to the Guide’s featured movie of the week. The program executes continuously until the theater manager enters a negative number to quit. At the end of the program, you should display the average star rating for the movie.
