A laborant in a laboratory does a number of antigen tests in one day. Write a program that
simulates the number of antigen tests done in a day in a laboratory, displays the number of
positives and negatives, and calculates the % of positives in one day. Your program needs
to first generate a random number that will show the number of tests done in a day. One
laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one).
Then for each of the tests, your program needs to generate a random number to show
whether they are positive or negative. In order to write this program, you need to have the
following three functions used by the main function:
test result (void): This function generates a test result. It should randomly
return either one or zero. 1 means positive test result and 0 means negative test result.
float positive percentage (int,int) : This function takes the total number of
positives and the total number of tests and returns the % of positives.…
The area of a rectangle is the rectangle’s length times its width. Write a program that asks for the length and width of two rectangles. The program should tell the user which rectangle has the greater area, the lesser area or if the areas are the same. Allow the user to continue to ask for measurements of two rectangles until he/she wishes to quit.

- 3) Write a program that reads an integer and prints how many digits it has by checking whether the number is >= 10, >= 100, and so on. However, if the number is greater than a million, just print "lots". If the number is negative, then first multiply it by -1.arrow_forwardA palindromic number is a number that is the same when written forwards or backwards. The first few palindromic numbers are therefore are: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, 323 Input a number from the user. Write a program that reverses the digits of a number. Use this program to find if the number is a palindrome. Print if the number is palindrome or not.arrow_forward4- Write a program that reads the average of 30 students and find the number of pass students , the number of fail students then print the results. 5- Write a program that reads 20 numbers then find the number of negative and positive numbers and the number of numbers equal to zero and print the results. 6- Write a program to read three numbers A,B,C then find whether A,B,C can form the sides of a triangle, if yes compute the parameter of the triangle , if no print the massage ( not a triangle), then determine whether A,B,C form the side of an (a)) equilateral triangle ,b) isosceles triangie ,c)) right angle triangle Hint: ( A,B,C can form a triangle if each side is less than the sum of the other two sides)arrow_forward
- Three numbersa. Write a program that reads three numbers and prints “all the same” if they are allthe same, “all different” if they are all different, and “neither” otherwise.b. Write a program that reads three numbers and prints “increasing” if they are inincreasing order, “decreasing” if they are in decreasing order, and “neither”otherwise. Here, “increasing” means “strictly increasing”, with each value largerthan its predecessor. The sequence 3 4 4 would not be considered increasing.c. Repeat part b. but before reading the numbers, ask the user whetherincreasing/decreasing should be “strict” or “lenient”. In lenient mode, thesequence 3 4 4 is increasing and the sequence 4 4 4 is both increasing anddecreasingarrow_forwardFind the first 10 square numbers that are greater than Long.MAX_VALUE.

An airline company has decided to apply a 10kg limitation for passengers' hand luggage and 20kg for their normal baggage. When passengers arrive, they enter their hand and normal luggage weight from the keyboard. If passengers exceed their normal baggage allowance of 10 dollars per gram, they pay 12 dollars per kg. Accordingly, write the program that calculates the baggage price of the airline they will go to according to the baggage values entered by the arriving passenger and keeps this from closing the program for each passenger. Note: If hand and normal baggage allowances are stretched below the maximum value, the payment amount will be considered not negative. An example printout is given on the right.

- 6. A palindrome is a number or text phrase that reads the same backwards or forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a program that reads a 5 digit integer and determines whether it is a palindrome. Hint: One way to do this is to use division (/) and modulus (%) operators to separate the number into individual digits.arrow_forwardCreate a different version of the program that: Takes a 3-digit number and generates a 6-digit number with the 3-digit number repeated, for example, 391 becomes 391391. The rule is to multiply the 3-digit number by 7*11*13. Takes a 5-digit number and generates a 10-digit number with the 5-digit number repeated, for example, 49522 becomes 4952249522. The rule is to multiply the 5-digit number by 11*9091. Times 11: A two-digit number can be easily multiplied by 11 in one's head simply by adding the digits and inserting that sum between the digits. For example, 43 * 11 has the resulting digits of 4, 4+3, and 3, yielding 473. If the sum between the digits is greater than 9, then the 1 is carried to the hundreds place. Complete the below program.

If there are two coordinate points of the line are given, then it is very easy to compute the line equation. Also you can find the distance between two points. Problem: Write a program to compute lines equation for a set of lines. The number of lines is read from the user. Each line is computed by generating two points randomly using Point2D API. In addition, distance between two points is computed. The program should display a table which include all information about each line. See sample runs below. Take into consideration: 1. Number of generated lines should be greater than zero. 2. Two point objects are constructed only once. Then just update the location of two points for each line using Point2D API methods. 3. x and y values of each point are generated randomly to be less than 100 and greater than 0. 4. Compute the distance between two points using…arrow_forward

If the character is 'c', the program reads from the user the radius rof a circle and prints its area. • If the user enters 'q', the program asks the user to enter the length and width of a quadrilateral. We assume the quadrilateral is either a square or rectangle. You should print if the quadrilateral is square or rectangle. • Otherwise, it prints "Wrong character" PS: Use the following formulas: area of circle=3.14*r Sample Run1: Enter a character (q or c): q Enter the Length and Width: 80 150 |It is a rectangle Sample Run2: Enter a character (q or c): q Enter the Length and Width: 80 80 It is a square Sample Run3: Enter a character (q or c): c Enter the radius: 2 The area of the circle is 12.56 Sample Run4: Enter a character (q or c): d Wrong characterarrow_forwardWrite a program that reads two integers, a and b, from the user.
