Debugging a code involves locating the errors in a code segment, and fixing them.
How to debug the code segment?When the program was run on GDB, the program give the following error
Main.java:62: error: reached end of file while parsing
This means that we need to add a closing brace to the end of the program.
A second run after fixing this error gives another set of errors:
Main.java:4: error: class Contribution is public, should be declared in a file named Contribution.java
It should be noted that GDB only allows you to create a program with the file name Main i.e. Main.java
This means that we change the Contribution keywords in the program to Main.
After this has been done, the program gives the following output:
It took 17 contributions to reach the goal.
The maximum contribution received was $189.0.
The minimum contribution received was $3.0
The average contribution amount was $60.0.
A total of $1012.0 was collected.
So, the corrected program is:
import java.io.*;
import java.util.*;
public class Main {
public void fileOperation(String inputFile, String outputFile) {
double max_contro = Double.MIN_VALUE;
double min_contro = Double.MAX_VALUE;
int total = 0;
int goal = 1000;
double current = 0.0;
// Reading from the file
try {
File file = new File(inputFile);
Scanner sc = new Scanner(file);
while (sc.hasNextLine()) {
double amt = Double.parseDouble(sc.nextLine());
current += amt;
total++;
if (amt < min_contro) {
min_contro = amt;
}
if (amt > max_contro) {
max_contro = amt;
}
if (current > goal) {
break;
}
}
} catch (Exception e) {
System.out.println("Error processing the file!");
}
double average_contro = Math.round((double) current / total);
// Writing to the file
try {
FileWriter writer = new FileWriter(outputFile, true);
BufferedWriter out = new BufferedWriter(writer);
out.write("It took " + total + " contributions to reach the goal.\nThe maximum contribution"
+ " received was $" + max_contro + ".\nThe minimum contribution"
+ " received was $" + min_contro + "\nThe average contribution amount was $"
+ average_contro + ".\nA total of $" + current + " was collected.");
out.newLine();
out.close();
} catch (Exception e) {
System.out.println("Error processing the file!");
}
}
// Driver method to test the code
public static void main(String[] args) {
String inputFile = "input.in";
String outputFile = "output.out";
Main obj = new Main();
obj.fileOperation(inputFile, outputFile);
}
}
Note that the filename must be Main.java in GDB and the input file is input.in

In Python write a program that reads a list of integers into a list as long as the integers are greater than zero, then outputs the values of the list.
Ex: If the input is:
10
5
3
21
2
-6
the output is:
[10, 5, 3, 21, 2]
Code hints: while user_input >0: #This is the number that is greater than 0 from the list that is entered.
print(user_numbers) #Prints out the numbers greater than zero that are inputted at the top part.
See the comments for explanations of what each line does.
Codeintegers = [] # Create an empty list to store the values
user_input = int(input()) # Get the first input
while user_input > 0: # Loop as specified
integers.append(user_input) # Add the value to the list
user_input = int(input()) # Get another input
print(integers) # Print the full list
what is the use of word processing software?
Answer:
A typical word processor enables the user to create documents, edit them using the keyboard and mouse, store them for later retrieval, and print them to a printer. Common word processing applications include Microsoft Notepad, Microsoft Word, and Corel WordPerfect.
Continuing with the program in problem #4: Box #10 has identical attributes to Box #07. Create box #10. Then, write two statements that will print out: one will compare the contents of Box #07 and Box #10, and the other will compare the contents of Box #21 and Box #23.
The program illustrates the use of conditional statements i.e. the if keyword
The two statementsThe statements that compare the boxes written in Python are as follows:
#Statement 1
if box07 > box10:
print("Box 07")
else
print("Box 10")
#Statement 2
if box21 > box23:
print("Box 21")

difference between primary and secondary storage
Answer:
Primary storage also called as main memory. RAM is an example of primary memory.
Secondary storage are popular as we use them for permanent storage.
Explanation:
Primary storage are temporary such RAM which are required for your program to execute. Without these storage, we can't use the computer for any operations. These memory keeps intermediate data and garbage out when the data no longer required.
On the other hand, when we need to store the data for future reference such as files, photos and videos we use secondary storage devices such as usb drive, hard disk etc.

Write a program that converts a decimal height in feet into feet and inches.
For instance; an input of 4.75 feet should become 4 feet and 9 inches.
The program to illustrate the conversion of the height is illustrated below.
How to illustrate the program?The information here is to convert 1 inch = 2.54 cm. First, we will take user input of height in cm. We first convert this to inches by dividing by 2.54
After that, we use Floor Division // and Modulo % by 12 to get feet and inches respectively.
The inches will be in a lot of decimals. We round this off to 2 decimal places and finally print out the converted height.
The code will be:
# Take user input for height in cm
height_cm = float(input("Enter your height in cm: "))
# Convert height to inches
height_in = height_cm / 2.54
# Get feet by taking floor division with 12
feet = height_in // 12
# Get inches by taking modulo division with 12
inches = height_in % 12
# Round off the inches to 2 decimal places
inches_rounded = format(inches, ".2f")
# Print out the height in feet and inches

What is necessary to execute a Python program?
A Python interpreter and typically a collection of modules must be installed on the computer system in order for Python programs to work.
What is a python language?Python is a general-purpose, high-level, interpreted programming language. Code readability is prioritized in its design philosophy, which makes heavy use of indentation.
Python is a language for writing source code, not binary code. You can (usually must) build obj files for C or C++ and link them into an executable after that. The C/C++ executable is a sourceless binary executable file.
The Python compiler/interpreter, on the other hand, executes Python source code directly. Naturally, the procedure itself is more intricate behind the scenes. However, the Python compiler/interpreter really runs the source from the user's perspective.
