Car A travels west at an average speed of x miles per hour and car B travels south at an average speed of y miles per hour. Write a program that prompts the user to enter: The average speed of both the cars The elapsed time (in hours and minutes, separated by a space) Ex: For two hours and 30 minutes, 2 30 would be entered
Answer:
Here is the C++ program:
#include <iostream> // to use input output functions
#include <cmath> // to use math functions like sqrt()
#include <iomanip> //to use setprecision method
using namespace std; //to access objects like cin cout
int main () { //start of main function
double speedA; //double type variable to store average speed of car A
double speedB; //double type variable to store average speed of car B
int hour; //int type variable to hold hour part of elapsed time
int minutes; //int type variable to hold minutes part of elapsed time
double shortDistance; // double type variable to store the result of shortest distance between car A and B
double distanceA; //stores the distance of carA
double distanceB; //stores the distance of carB
double mins,hours; //used to convert the elapsed time
cout << "Enter average speed of car A: " << endl; //prompt user to enter the average speed of car A
cin >> speedA; //reads the input value of average speed of car A from user
cout << "Enter average speed of car B: " << endl ; //prompt user to enter the average speed of car B
cin >> speedB; //reads the input value of average speed of car A from user
cout << "Enter elapsed time (in hours and minutes, separated by a space): " << endl; //prompts user to enter elapsed time
cin>> hour >> minutes; //reads elapsed time in hours and minutes
mins = hour * 60; //computes the minutes using value of hour
hours = (minutes+mins)/60; //computes hours using minutes and mins
distanceA = speedA * (hours); // computes distance of car A
distanceB = speedB * (hours); //computes distance of car B
shortDistance =sqrt((distanceA * distanceA) + (distanceB * distanceB)); //computes shortest distance using formula √[(distanceA)² + (distanceB)²)]
cout << "The (shortest) distance between the cars is: "<<fixed<<setprecision(2)<<shortDistance;
//display the resultant value of shortDistance up to 2 decimal places
Explanation:
I will explain the program with an examples:
Let us suppose that the average speeds of cars are:
speedA = 70
speedB = 55
Elapsed time in hours and minutes:
hour = 2
minutes = 30
After taking these input values the program control moves to the statement:
mins = hour * 60;
This becomes
mins = 2 * 60
mins = 120
Next
hours = (minutes+mins)/60;
hours = (30 + 120) / 60
= 150/60
hours = 2.5
Now the next two statements compute distance of the cars:
distanceA = speedA * (hours);
this becomes
distanceA = 70 * (2.5)
distanceA = 175
distanceB = speedB * (hours);
distanceB = 55 * (2.5)
distanceB = 137.5
Next the shortest distance between car A and car B is computed:
shortDistance = sqrt((distanceA * distanceA) + (distanceB * distanceB));
shortDistance = sqrt((175 * 175) + (137.5 * 137.5))
= sqrt(30625 + 18906.25)
= sqrt(49531.25)
= 222.556173
shortDistance = 222.56
Hence the output is:
The (shortest) distance between the cars is: 222.56

1) Create the following 2D array in one instruction: {{1,2,3,4,5}, {1,2,3,4,5}, {1,2,3,4,5}} // your code goes below:
2) Create the above 2D array using a for loop and the below method: public static int[] simpleArray(int n) { int[] result = new int[n]; for (int i=0; i
Answer:
1)
int[][] a2dArray = {{1,2,3,4,5},{1,2,3,4,5},{1,2,3,4,5}};
2)
public class Main
{
public static void main(String[] args) {
int[][] a2dArray2 = new int[3][5];
for (int i=0; i<3; i++) {
a2dArray2[i] = simpleArray(5);
}
for (int i=0; i<a2dArray2.length; i++) {
for (int j=0; j<a2dArray2[i].length; j++){
System.out.print(a2dArray2[i][j] + "");
}
System.out.println();
}
}
public static int[] simpleArray(int n){
int[] result = new int[n];
for (int i=0; i<n; i++) {
result[i] = i+1;
}
return result;
}
}
Explanation:
1) To create a 2D array you need to write the type, two brackets and the name on the left hand side. Put the values on the right hand side.
2) Declare the array. Since there will be 3 rows and 5 columns, put these values in the brackets on the right hand side.
Create a for loop that iterates 3 times. Call the method simpleArray inside the loop so that each row of the a2dArray2 array will be set. Be aware that simpleArray method takes an integer as parameter and creates a 1D array, the numbers in the array starts from 1 and goes to the parameter value. That is why calling the method simpleArray (with parameter 5) 3 times will create a 2D array that has 3 rows and 5 columns.
Then, use a nested for loop to display the 2D array.

let fabcd = a.(if b then c else d)
Which of the following must hold (zero, one or more answers can be correct)?
A. The type of a is int array.
B. The type of b is bool.
C. The type of c is int.
D. The type of d is int.
E. The return type of f is int.
Answer:
The type of b is bool ( B )
The type of c is int ( C )
The type of d is int ( D )
Explanation:
The options that must hold zero are: The type of b is bool,The type of d is int and The type of c is int.
If b is true then c or d is true because c and d are int. this is because b been a true/false means that d and c are boolean int. because d and c are assigned to integers
The statements that must hold are:
b. The type of b is bool c. The type of c is int d. The type of d is int
The definition is given as:
let fabcd = a.(if b then c else d)
From the above definition, we have the following if condition
if b then c else d
This means that:
Variable b can only take either true or false, as its value.
So, b is of Boolean type
Variables c and d can take any numerical data type such as int, floats, and any character type such as char and string.
This means that:
Options (c) and (d) can also hold.
Hence, the true options are: (b), (c) and (d)

Write a program that computes how much ocean levels are expected to rise during the next 15 years if they continue rising at this rate. Display the answer in both centimeters and inches.
Answer:
Program in Python is as follows:
rise = 3.1
for i in range(1,16):
print("Rise in Year "+str(i))
cm = rise * 0.1 * i
inch = rise/25.4 * i
print(str(cm)+" centimetres")
print(str(inch)+" inches")
Explanation:
This line initializes the rise of the ocean level
rise = 3.1
The following iterates from 1 to 15 (which stands for year)
for i in range(1,16):
print("Rise in Year "+str(i))
This calculates the rise in each year in centimetre
cm = rise * 0.1 * i

Write a program that converts a time in 12-hour format to 24-hour format. The program will prompt the user to enter a time in HH:MM:SS AM/PM form. (The time must be entered exactly in this format all on one line.) It will then convert the time to 24 hour form. You may use a string type to read in the entire time at once, including the space before AM/PM, or you may choose to use separate variables for the hours, minutes, seconds and AM/PM.
Answer:
This program is written in Python
inputtime = input("HH:MM:SS AM/PM: ")
splittime = inputtime.split(":")
secondAM = splittime[2].split()
if secondAM[1] == "AM":
print(splittime[0]+":"+splittime[1]+":"+secondAM[0])
elif secondAM[1] == "PM":
HH = int(splittime[0])
HH = HH + 12
print(str(HH)+":"+splittime[1]+":"+secondAM[0])
Explanation:
This line prompts user for input
inputtime = input("HH:MM:SS AM/PM: ")
This line splits the input string to HH, MM and "SS AM/PM"
splittime = inputtime.split(":")
This line splits "SS AM/PM" to SS and AM/PM
secondAM = splittime[2].split()
This line checks if time is AM
if secondAM[1] == "AM":
This line prints the equivalent time
print(splittime[0]+":"+splittime[1]+":"+secondAM[0])
Else;
elif secondAM[1] == "PM":
The equivalent 24 hour is calculated
HH = int(splittime[0]) + 12
This line prints the equivalent time
print(str(HH)+":"+splittime[1]+":"+secondAM[0])
