PRG 211 Week 5 Labs

Lab 11.1 Miles to track laps

One lap around a standard high-school running track is exactly 0.25 miles. Write a program that takes a number of miles as input, and outputs the number of laps.

Ex: If the input is 1.5, the output is:
6.0

Ex: If the input is 2.2, the output is:
8.8

Your program should define and call a function:
Function MilesToLaps(float userMiles) returns float userLaps

Lab 11.2 Driving cost

Write a function DrivingCost with parameters drivenMiles, milesPerGallon, and dollarsPerGallon, that returns the dollar cost to drive those miles. All items are of type float.

Ex: If the function is called with 50 20.0 3.1599, the function returns 7.89975.

Define that function in a program whose inputs are the car's miles/gallon and the gas dollars/gallon (both floats). Output the gas cost for 10 miles, 50 miles, and 400 miles, by calling your DrivingCost function three times.

Ex: If the input is 20.0 3.1599, the output is:
1.57995 7.89975 63.198

Note: Small expression differences can yield small floating-point output differences due to computer rounding. Ex: (a + b)/3.0 is the same as a/3.0 + b/3.0 but output may differ slightly. Because our system tests programs by comparing output, please obey the following when writing your expression for this problem. In the DrivingCost function, use the variables in the following order to calculate the cost: drivenMiles, milesPerGallon, dollarsPerGallon.

Lab 11.3 Step counter

A pedometer treats walking 2,000 steps as walking 1 mile. Write a program whose input is the number of steps, and whose output is the miles walked. If the input is 5345, the output is 2.6725.

Your program should define and call a function:
Function StepsToMiles(integer userSteps) returns float numMiles

Lab 11.4 Leap year

A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are:

1) The year must be divisible by 4

2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400

Some example leap years are 1600, 1712, and 2016.

Write a program that takes in a year and determines whether that year is a leap year. If the input is 1712, the output is: 1712 is a leap year. If the input is 1913, the output is: 1913 is not a leap year.

Your program must define and call a function:

Function OutputLeapYear(integer inputYear) returns nothing
The function should output whether the input year is a leap year or not.

Lab 11.5 Max and min numbers

Write a program whose inputs are three integers, and whose outputs are the largest of the three values and the smallest of the three values. If the input is 7 15 3, the output is:
largest: 15
smallest: 3

Your program should define and call two functions:
Function LargestNumber(integer num1, integer num2, integer num3) returns integer largestNum
Function SmallestNumber(integer num1, integer num2, integer num3) returns integer smallestNum
The function LargestNumber should return the largest number of the three input values. The function SmallestNumber should return the smallest number of the three input values.

Lab 11.6 Output values below an amount

Write a program that first gets a list of six integers from input. The first five values are the integer list. The last value is the upper threshold. Then output all integers less than or equal to the threshold value.

Ex: If the input is 50 60 140 200 75 100, the output is:
50 60 75
For coding simplicity, follow every output value by a space, including the last one.

Such functionality is common on sites like Amazon, where a user can filter results.

Your program should define and use a function:
Function outputIntsLessThanOrEqualToThreshold(integer array(?) userVals, integer upperThreshold) returns nothing
