Segmentation Faults Recall what causes segmentation fault and bus errors from lecture. Common cause is an invalid pointer or address that is being dereferenced by the C program. Use the program average.c from the assignment page for this exercise. The program is intended to find the average of all the numbers inputted by the user. Currently, it has a bus error if the input exceeds one number. Load average.c into gdb with all the appropriate information and run it. Gdb will trap on the segmentation fault and give you back the prompt. First find where the program execution ended by using backtrace (bt as shortcut) which will print out a stack trace. Find the exact line that caused the segmentation fault.
Q13. What line caused the segmentation fault?
Q14. How do you fix the line so it works properly?
You can recompile the code and run the program again. The program now reads all the input values but the average calculated is still incorrect. Use gdb to fix the program by looking at the output of read_values. To do this, either set a breakpoint using the line number or set a breakpoint in the read_values function. Then continue executing to the end of the function and view the values being returned. (To run until the end of the current function, use the finish command).
Q15. What is the bug? How do you fix it?
//average.c
#include
/*
Read a set of values from the user.
Store the sum in the sum variable and return the number of values
read.
*/
int read_values(double sum) {
int values=0,input=0;
sum = 0;
printf("Enter input values (enter 0 to finish):\n");
scanf("%d",&input);
while(input != 0) {
values++;
sum += input;
scanf("%d",input);
}
return values;
}
int main() {
double sum=0;
int values;
values = read_values(sum);
printf("Average: %g\n",sum/values);
return 0;
}

Answer 1

Answer:

See Explanation

Explanation:

Q13. Line that caused the segmentation fault?

The segmentation fault was caused by line 15 i.e. scanf("%d",input);

Q14. How the line was fixed?

The reason for the segmentation fault is that the instruction to get input from the user into the integer variable "input" was not done correctly.

The correction to this is to modify scanf("d",input) to scanf("%d",input);

Q15. The bug?

The bug is that the method needs to return two value; the sum of the inputted numbers and the count of the inputted numbers.

However. it only returns the count of the inputted number.

So, the average is calculated as: 0/count, which will always be 0

How it was fixed?

First, change the method definition to: void and also include an array as one of its parameters.

void read_values(double sum, double arr []) {

Next:

assign sum to arr[0] and values to arr[1]

In the main method:

Declare an array variable: double arr [2];

Call the read_values function using: read_values(sum,arr);

Get the sum and values using:

sum = arr[0];

values = arr[1];

Lastly, calculate and print average:

printf("Average: %g\n",sum/values);

Write a program called clump that accepts an ArrayList of strings as a parameter and replaces each pair of strings with a single string that consists of the two original strings in parentheses separated by a space. If the list is of odd length, the final element is unchanged. For example, suppose that a list contains

Answers

Answer:

In Java:

public static void clump(ArrayList<String> MyList) {  

   for(int i = 0; i<MyList.size()-1;i++){

       String newStr = "(" + MyList.get(i) + " "+ MyList.get(i + 1) + ")";

  MyList.set(i, newStr);

  MyList.remove(i + 1);

   }

       System.out.println("Updated ArrayList: " + MyList);

 }

Explanation:

First, we define the method

public static void clump(ArrayList<String> MyList) {  

Next, we iterate through the ArrayList

   for(int i = 0; i<MyList.size()-1;i++){

This clumps/merges every other ArrayList element

       String newArr = "(" + MyList.get(i) + " "+ MyList.get(i + 1) + ")";

This updates the elements of the ArrayList

  MyList.set(i, newArr);

This removes ArrayList elements at odd indices (e.g. 1,3...)

  MyList.remove(i + 1);

   }

This prints the updated List

       System.out.println("Updated ArrayList: " + MyList);

Write a program which will enter information relating to a speeding violation and then compute the amount of the speeding ticket. The program will need to enter the posted speed limit, actual speed the car was going, and whether or not the car was in a school zone and the date of the violation. Additionally, you will collect information about the driver (see output for specifics). The way speeding tickets are computed differs from city to city. For this assignment, we will use these rules, which need to be applied in this order:

Answers

Answer:

In Java:

import java.util.*;

public class Main{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 float speedlimit, actualspeed;

 String ddate;

 int schoolzone;

 System.out.print("Speed Limit: ");

 speedlimit = input.nextFloat();

 System.out.print("Actual Speed: ");

 actualspeed = input.nextFloat();

 System.out.print("Date: ");

 ddate = input.nextLine();

 System.out.print("School Zone (1-Yes): ");

 schoolzone = input.nextInt();

 float ticket = 75;

 ticket += 6 * (actualspeed - speedlimit);

 

 if(actualspeed - speedlimit > 30){

     ticket+=160;

 }

 if(schoolzone == 1){

     ticket*=2;

 }  

 System.out.print("Date: "+ddate);

 System.out.print("Speed Limit: "+speedlimit);

 System.out.print("Actual Speed: "+actualspeed);

 System.out.print("Ticket: "+ticket);

}

}

Explanation:

See attachment for complete program requirements

This declares speedlimit and actualspeed as floats

float speedlimit, actualspeed;

This declares ddate as string

 String ddate;

This declares schoolzone as integer

 int schoolzone;

This prompts the user for speed limit

 System.out.print("Speed Limit: ");

This gets the speed limit

 speedlimit = input.nextFloat();

This prompts the user for actual speed

 System.out.print("Actual Speed: ");

This gets the actual speed

 actualspeed = input.nextFloat();

This prompts the user for date

 System.out.print("Date: ");

This gets the date

 ddate = input.nextLine();

This prompts the user for school zone (1 means Yes, other inputs means No)

 System.out.print("School Zone (1-Yes): ");

This gets the input for schoolzone

schoolzone = input.nextInt();

This initializes ticket to $75

 float ticket = 75;

This calculates the additional cost based on difference between speed limits and the actual speed

 ticket += 6 * (actualspeed - speedlimit);

If the difference between the speeds is greater than 30, this adds 160 to the ticket  

 if(actualspeed - speedlimit > 30){

     ticket+=160;

 }

If it is in a school zone, this doubles the ticket

 if(schoolzone == 1){

     ticket*=2;

 }  

The following print the ticket information

 System.out.print("Date: "+ddate);

 System.out.print("Speed Limit: "+speedlimit);

 System.out.print("Actual Speed: "+actualspeed);

 System.out.print("Ticket: "+ticket);

A student will not be allowed to sit in exam if his/her attendance is less than 75% .
Take the following input from user

Is student allowed to sit in exam or not .

Answers

Answer:

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

 

 Scanner input = new Scanner(System.in);

 

 int classesHeld, classesAttended;

 double percentage;

 

 System.out.print("Enter number of classes held: ");

 classesHeld = input.nextInt();

 

 System.out.print("Enter number of classes attended: ");

 classesAttended = input.nextInt();

 

 percentage = (double) classesAttended / classesHeld;

 

 if(percentage < 0.75)

     System.out.println("You are not allowed to sit in exam");

 else

     System.out.println("You are allowed to sit in exam");

}

}

Explanation:

Import the Scanner to be able to get input from the user

Create a Scanner object to get input

Declare the variables

Ask the user to enter classesHeld and classesAttended

Calculate the percentage, divide the classesAttended by classesHeld. You also need to cast the one of the variable to double. Otherwise, the result would be an int

Check the percentage. If it is smaller than 0.75 (75% equals 0.75), print that the student is not allowed. Otherwise, print that the student is allowed

Write a program that calculates the occupancy rate for a hotel. The program should start by asking the user how many floors the hotel has. A for loop should then iterate once for each floor. In each iteration of the for loop, the program should ask the user for the number of rooms of the floor and how many of them are occupied. After all of the iterations are complete the program should display how many rooms the hotel has, how many of them are occupied, and the percentage of rooms that are occupied.

Answers

Answer:

In Python:

floor = int(input("Number of floors: "))

totalrooms = 0

totaloccupied = 0

for i in range(floor):

   rooms = int(input("Rooms in floor "+str(i+1)+": "))

   occupied = int(input("Occupied Rooms in floor "+str(i+1)+": "))

   totalrooms = totalrooms + rooms

   totaloccupied = totaloccupied + occupied

   

print("Total Rooms: "+str(totalrooms))

print("Total Occupied: "+str(totaloccupied))

print("Percentage Occupied: "+str(round(100*totaloccupied/totalrooms,2))+"%")

Explanation:

This line prompts the user for number of rooms

floor = int(input("Number of floors: "))

This line initializes totalrooms to 0

totalrooms = 0

This line initializes totaloccupied to 0

totaloccupied = 0

This iterates through the floors

for i in range(floor):

This gets the number of rooms in each floor

   rooms = int(input("Rooms in floor "+str(i+1)+": "))

This gets the number of occupied rooms in each floor

   occupied = int(input("Occupied Rooms in floor "+str(i+1)+": "))

This calculates the total number of rooms

   totalrooms = totalrooms + rooms

This calculates the total number of occupied rooms

   totaloccupied = totaloccupied + occupied

   

This prints the total number of rooms

print("Total Rooms: "+str(totalrooms))

This prints the total number of occupied rooms

print("Total Occupied: "+str(totaloccupied))

This prints the percentage of occupied rooms to 2 decimal places

print("Percentage Occupied: "+str(round(100*totaloccupied/totalrooms,2))+"%")
