Write a program that simulates flipping a coin repeatedly until three consecutive
       heads are tossed. The program should then display the total number of times the coin was
       flipped. The user does not have to enter any information and we must use a while loop.

What is the list of commands required to upgrade a cisco IOS, ensuring that the system will use the IOS file when booting?

1. This question is related to making an object method call by reference instead of by value. Use the (CallValueTest.java). Convert the calculation method (calc(..) ) in the Test class. You need to modify the Test class attributes and constructor to support this new cal (…) method. Your program should display:

Before call obj.a 15 obj.b is 20

Before call obj.a 30 obj.b is 10

CallValueTest.java

package com.Assignment3.Q1;

class Test {
  
   void calc(int a, int b) {
       a *= 2;
       b /= 2;
       System.out.println(" in calc a = " + a + " b = " + b);
   }
  
}
public class CallByValueTest {
   public static void main (String args[]) {
       Test ob = new Test();
       int a =15, b = 20;
       System.out.println ("Before calc :a = " + a + " b " + b);
      
       ob.calc (a, b );
      
       System.out.println(" After calc: a = " + a + " b " + b);
      
   }
}

Write a C program that calculates the percent saves for a hockey goalie for 4 games and
the overall percentage of saves which is saves divided by the sum of goals plus saves.
input->process->output->repeat
The program should prompt the user to enter the number of goals and the number of
saves for each of the 4 games. The program should then calculate and display the percent
saves obtained for each game. Once processing is complete for the games, the program
will calculate the overall percent saves (total saves / sum of total saves and total goals
and display the results. Then print a friendly exit message as shown below.
Once you create, compile, link and run your program, your program should present the
following input/output dialog to the user:

Welcome to the Goalie Saves Analysis
This program will calculate the percentage of saves for
a hockey goalie for 4 games after you have entered the
games and saves for the goalie.

Enter the number of goals for game #1: 3
Enter the number of saves for game #1: 22
The percent saves for game #1 is 88.0%

Enter the number of goals for game #2: 4
Enter the number of saves for game #2: 33
The percent saves for game #2 is 89.2%

Enter the number of goals for game #3: 1
Enter the number of saves for game #3: 16
The percent saves for game #3 is 94.1%

Enter the number of goals for game #4: 0
Enter the number of saves for game #4: 22

The percent saves for game #4 is 100.0%
The percent saves for 4 games for this goalie is 92.1%

Thanks for using the Bruins Goalie Saves Analysis program.

Advanced Inheritance Concepts (Exercise 7)

The Cullerton Park District holds a mini-Olympics each summer. Create a class named Participant with fields for a name, age, and street address. Include a constructor that assigns parameter values to each field and a toString() method that returns a String containing all the values. Also include an equals() method that determines two participants are equal if they have the same values in all three fields.

Create an application with two arrays of at least eight participants each—one holds participants in the mini-marathon, and the other holds participants in the diving competition. Prompt the user for participant values. After the data values are entered, display values for participants who are in both events.

Participant.java

_{public class Participant
{
// private variables here}

_{public Participant(String n, int a, String add)
{
// constructor code here
}
public String getName()
{
// method code here
}
public int getAge()
{
// method code here
}
public String getAddress()
{
// method code here
}
public String toString()
{
// method code here
}
public boolean equals(Participant p)
{
// method code here
}
}}

for(j = 0; j < divers.length; ++j)

System.out.println(marathoners[i].toString());
}

Possible Answer:

Participants who are in both events:

Participant_2

Apartment No. 6

Participant_7

Complete the following assignment in C programming language.

1. Get the user’s first name and store it to a char array
   • Declare a character array to hold at least 20 characters.
   • Ask for the user’s first name and store the name into your char array.
   • Hint: Use %s for scanf. %s will only scan one word and cannot scan a name with spaces.
2. Get 3 exam scores from the user:
   • Declare an array of 3 integers
   • Assume the scores are out of 100, and use a for loop to get user’s input
   • Your prompts should print out which exam score you are asking for:
     1. Example: “What is the score of Exam #1?” … “What is the score of Exam #3?”
   • Warning: Be careful of your array indexes!
3. Find out the average exam score:
   • Use a for loop to calculate the sum of all exams.
   • Divide the sum by 3 to get the average and store the is data in a variable.
4. Print out the summary for the use similar to:
   • “Hello NAME, based on your exam score of 80, 90, and 100, your average is 90.0 with a letter of an ‘A.’”

Reserved words are keywords which will not be used for identifier. For example, Java reserved words include for, while, if and etc. What are the disadvantages of having “too many reserved words”?

Q. Operating systems are the most indispensable components of the software interface between users and the hardware of their computer systems. Explain.

Create a class that has a method that uses the ‘this’ keyword as the return statement. This method (called increment( ) in the class that you have just created ) increments the private integer field (private i ) in the class.   In the main ( ) method, if you increment (using the ‘this’ with increment() call) four times, you should see the following display:

i is = 4

Python to analyze weather data from a file. First, go to this Minnesota Dept. of Natural Resources web page, which displays weather data for Minneapolis on each day of the year 2000. Click the CSV link to download a file containing the data. The file is a “comma-separated values” text file of weather data. The first few lines look like this:

   "Date","Maximum Temperature degrees (F)","Minimum Temperature...
   "2000-01-01","35.0","24.0","T","0.00","0.00"
   "2000-01-02","35.0","29.0","0.04","0.50","0.00"
   "2000-01-03","29.0","24.0","T","T","0.00"

The first line of the file contains column headings, and each of the remaining lines contain weather data for one specific day. These lines contain a date followed by the high temperature, low temperature, precipitation, snowfall, and snow depth recorded on that day. A value of “T” indicates a “trace” amount of precipitation or snowfall, which you can regard as zero.

Write some Python code to load the data from the file into one or more NumPy arrays. Then compute the following:

1. Compute the average high and low temperatures for each month. For example, the average high temperature for January is the average of the high temperatures for all 31 days in January.

2. Compute the number of days each month that received no precipitation. (Regard a “trace” amount of precipitation as zero precipitation.)

3. Compute the total snowfall for each month. (Again, regard a “trace” amount as no snowfall.)

4. Find the day that had the greatest difference between the high and low temperature for that day.
