Q3: (Tax Calculator) Develop a Java program that determines the total tax for each of four citizens. The tax rate is 10% for earnings up to 50,000 RM earned by each citizen and 15% for all earnings in excess of that ceiling. You are given a list with the citizens’ names and their earnings in a given year. Your program should input this information for each citizen, then determine and display the citizen’s total tax. Use class Scanner to input the data.

CPU Usage
We have the hourly average CPU usage for a worker's computer over the course of a week. Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight.
Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart:
When does the worker typically take lunch?
Did the worker do work on the weekend?
On which weekday did the worker start working on their computer at the latest hour?

The statementy = floor(x * 10 + 0.5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor(x * 100 + 0.5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines fourfunctions to round a number x in various ways:A. roundToInteger(number)B. roundToTenths(number)C. roundToHundredths(number)D. roundToThousandths(number)For each value read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth and the number rounded to the nearest thousandth.arrow_forward6. //Program 4.6 #include #include int main (){ char c1, c2, с3, с4; cl=65; c2='A'; c3=0x41; c4=0101; printf("%c %d %f %s", c1, c2, c3, c4); getch(); return 0; H N M 4567 o Oarrow_forward(Enhancing Class Time) Modify the Time class of Figs. 17.4–17.5 to include a tick memberfunction that increments the time stored in a Time object by one second.

Identify which of the two points have the furthest x- and y-coordinates independently. Example: this point has (-5, 1) and the other point has (4, 9). In the x-coordinate of the two points, -5 is further from the origin than 4. In the y-coordinate of the two points, 9 is further from the origin than 1. Hence, we return a new point bearing the coordinates (-5, 9).arrow_forward

(Dice Rolling) Write a program that simulates the rolling of two dice. The program should use rand to roll the first die and should use rand again to roll the second die. The sum of the two values should then be calculated. [Note: Each die can show an integer value from 1 to 6, so the sum of the two values will vary from 2 to 12, with 7 being the most frequent sum and 2 and 12 being the least frequent sums.] Figure 7.26 shows the 36 possible combinations of the two dice. Your program should roll the two dice 10,000 times. Use a one-dimensional array to tally the numbers of times each possible sum appears. Print the results in a tabular format. Also, determine if the totals are reasonable (i.e., there are six ways to roll a 7, so approximately one-sixth of all the rolls should be 7). 1 2 3 4 5 1 2 4 6 7 3 4 6 7 3 4 5 7 8 9 4 7 8 9 10 7 8 10 11 7 10 11 12 Row\Col 3.arrow_forward

Write a test program that uses isPrime to determine and prints all the prime numbers between 1 and 1000. Display 10 numbers per line.arrow_forward14.
