please fix the code at the bottom to also report the percentages as well as the counts. the person who did it forgot this part . the code is bellow the instructions:

We will generate random values, but they should be limited to 0, 1, 2, or 3. To do this, think of a way to map the random value to a small value; there are many ways to do this, however, the way you choose must be reproducible. That is, if it maps value X to the value 2, it should do that every time the value is X. Create a function that accomplishes random number generation and mapping: the function should return a single integer that is a random value of 0, 1, 2, or 3. It does not need any inputs. To verify that it works, have your program print about 20 from it. If your program gives you values like -1 or 4, you know you have a problem. Also, if it never generates one of the values (0, 1, 2, or 3), then there is a problem.

Then create an array of 4 ints. Initialize that array to 0 values. Have your program prompt the user for an integer number, read it in, then generate that many random values (0, 1, 2, or 3). Do not show the random values. Instead, count them, i.e., every time the function produces a 0, the integer at array position 0 should be incremented. Once all the random numbers have been processed, display the counts. Verify that the numbers make sense; if your program says that there were 4 zero values, 6 ones, 5 twos, and 3 threes, but it was supposed to generate 20 values, you know there is a problem because 4+6+5+3 = 18, not 20. Also have your program report the percentages as well as the counts. The percentages should be shown with one digit after the decimal, and they should add up to 100% (neglecting any round-off error).

Test your program a few times, and note the relative number of each generated value. Assuming an even distribution, you would see the same counts for each value, i.e. 0 would be generated 25% of the time, 1 would be 25% of the time, etc. The more values the program generates, the closer to 25% each one should be.

Prepare the log like you normally do: use "cat" to show the C programs, use "gcc" to compile them, and show that the programs run.

code:

#include<stdio.h>
#include<stdlib.h>
int main()
{
int seed;
// Taking seed value as input from the user
printf("Enter a seed value (0 to quit): \n");
scanf("%d", &seed);
// Running the loop until user enters 0 to quit
// count array will count frequency of 0 , 1 , 2 ,3
int count[4];
for (int i = 0; i < 4; i++) count[i] = 0;
while (seed != 0)
{
// Passing seed value to the function srand()
srand(seed);
// Printing 5 random values
for (int i = 0; i < 5; i++) {
// generae a random number
// and take it modulo with 4
int rand_num = rand() % 4;
printf("%d ", rand_num);
count[rand_num]++;
}
printf("\n");
// Taking next seed value as input from the user
printf("Enter a seed value (0 to quit): \n");
scanf("%d", &seed);
}
// print count of each element [0-3]
for (int i = 0; i < 4; i++) {
printf("Count of %d = %d\n", i , count[i]);
}

return 0;
}

Tombro Industries is in the process of automating one of its plants and developing a flexible manufacturing system. The company is finding it necessary to make many changes in operating procedures. Progress has been slow, particularly in trying to develop new performance measures for the factory.

In an effort to evaluate performance and determine where improvements can be made, management has gathered the following data relating to activities over the last four months:

The president has read in industry journals that throughput time, MCE, and delivery cycle time are important measures of performance, but no one is sure how they are computed. You have been asked to assist the company, and you have gathered the following data relating to these measures:

Required:

1-a. Compute the throughput time for each month. (Round your answers to 1 decimal place.)

1-b. Compute the manufacturing cycle efficiency (MCE) for each month. (Round your answers to 1 decimal place.)

1-c. Compute the delivery cycle time for each month. (Round your answers to 1 decimal place.)

3-a. Refer to the inspection time, process time, and so forth, given for month 4. Assume that in month 5 the inspection time, process time, and so forth, are the same as for month 4, except that the company is able to completely eliminate the queue time during production using Lean Production. Compute the new throughput time and MCE. (Round your answers to 1 decimal place.)

3-b. Refer to the move time, process time, and so forth, given for month 4. Assume that in month 6 the inspection time, process time, and so forth, are the same as in month 4, except that the company is able to eliminate both the queue time during production and the inspection time using Lean Production. Compute the new throughput time and MCE.. (Round your answers to 1 decimal place.)

Pseudocode for the main method:

Print the headings

            Print the directions

            Prompt for the month

            If the month is an integer       (Hint: Use the Scanner class hasNextInt method.)

                        Input the integer for the month

                        Get the string for the month (Use your method)

            Otherwise

                        Input the string for the month

                        Get the integer for the month (Use your method)

            Prompt for the day

            Input the day

            Prompt for the year

            Input the year

            Get the holiday

            Print the output

THE PROBLEM:

You must use switch statements for some part of the homework.

Write a program that inputs a month, day, and year from the user and outputs the corresponding date in the following two standard date formats:

6/12/2005      June 12, 2005

Also your program must print the name of any holiday associated with the date.

For example:

             3/17/2010        March 17, 2010           St. Patrick’s Day

Your program should ask the user how many times the user wants to run the code and then you need to use a for loop to repeat the run that many times.

REQUIREMENTS:

You must use good programming style.

The user can enter the month either as a numeric value or a String. i.e. the user could enter a 5 or May.

You may assume the data that the user enters is valid data.

Your program must print a report similar to that shown in the sample output on the last page of this handout.

You must solve this problem by implementing and using the following methods:

printDirections

void method that prints a message to the user that explains what the program will do and how the month data can be entered. (See the sample output above.)

getMonthString

method that has 1 parameter, the month as an integer (1..12).

This method returns the corresponding name of the month as a String.

getMonthNumber

method that has 1 parameter, the name of the month in a String.

This method returns the corresponding integer value for that month name.

HINT: Before you read the data for the month, use the Scanner class hasNextInt method to determine what kind of data the user entered for the month. Using hasNextInt you can determine if the user is entering an integer for the month or not.

            getHoliday

                        This method has 2 int type parameters for month and day.

                        The method returns a String that is the name of a holiday that is associated with the date represented by the parameters. If there is no holiday associated with that date, then the method returns an empty String (“”).

                        Use nested switch statements to implement this method. Use one switch statement for the months. Inside the case for each month, use a switch statement that has a case for each day in that month that is a holiday. Inside each of those day cases, set the holiday string to the name of the holiday.

NOTE: You can also include holidays for your birthday, anniversary, or whatever …

isEaster

                        This method has 3 int type parameters for month, day and year.

This method returns true if the date represented by the 3 parameters is Easter, otherwise it returns false.

To implement this method:   use the following formula to figure out the month and the day of easter for the given year.

goldenNumber = (year % 19) + 1;

a = (24 + 19*(goldenNumber - 1)) % 30;   b = a - a/28;

c = (year + year/4 + b - 13) % 7;   d = b - c;

easterMonth = 3 + (d + 40)/44;

easterDay = d + 28 - 31*(easterMonth/4);

To use this method, you will have to add a third parameter to the getHoliday method for the year, and then inside the getHoliday method, after the switch statements, call this method.

NOTE: If the holiday string is already longer than 0, this day is already associated with another holiday,

(For example, maybe “Grandma’s Birthday”, then getHoliday should return “Easter and Grandma’s Birthday”.

To test the isEaster method, make April 4 “Grandma’s Birthday” and test this method using 4/4/2010. Also test it for Easter in a year where Easter is not on April 4.

Here is a list of holidays that your need needs to generate the appropriate output:

1/1 "New Year's Day";                            

1/18 "Martin Luther King Jr. Day";                            

2/2 "Ground Hog Day";

2/12 "Abraham Lincoln's Birthday";

2/14 "St. Valeninte's Day";

2/22 "George Washington's Birthday";

3/17 "St. Patrick's Day";   4/1 "April Fool's Day";

4/4 "Grandma's Birthday";

4/22 "Earth Day";

4/30 "Arbor Day";

5/1 "May Day";

5/5 "Cinco de Mayo";

7/4 "Independence Day";

8/1 "International Friendship Day";

10/1 "Columbus Day";

10/31 "Halloween";                         

11/11 "Vereran's Day";

12/25 "Christmas";

12/31 "New Year's Eve";                              

?? "Easter";
