- 23. A perfect number is a positive integer that is equal to the sum of its positive divisorsexcept the number itself. The first two perfect numbers are 6 and 28 since 6=1+2+3and 28=1+2+4+7+14. Write a computer program that finds thefirst four perfect numbers1. Write a program that prints your full name. Write a program that prints your full name using asterisk(*). Write a program that prints a square, a rectangle and a triangle using asterisk. Write a program that adds THREE(3) numbers. Write a program that multiply THREE(3) numbers. Write a program that divides TWO(2) numbers.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 anddecreasing
- 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.Create 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. Create 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…Q1: Write a program that reads a set of N integers. Then, the program finds and outputs the sum of the even values and the sum of the odd values of them. For example: if the value entered for N=5, and the five integers are 3, 6, 2, 9, 7. Then the sum of even values (6+2 = 8), and the sum of odd values (3+9+7 = 19) Q2: Write a program that reads some numbers until it reaches a specific value (assume -1 is a stop value in this case). The program should find and outputs the average of all of the numbers (between 10...40) except the stop value (-1). For example: If the numbers look like: 12 5 30 48 -1. Then, the average of the numbers: (12+30)/2 = 21.
- write a program in python Write a program that will allow a student to enter their name and then ask them to solve 10 mathematical equations. The program should display two random numbers that are to be added, such as: 247 + 129 The program should allow the student to enter the answer. The program should then display whether their answer was right or wrong, and accumulate the right values. After the 10 questions are asked, calculate the average that was correct. Then display the student name, the number correct, and the average correct in both decimal and percentage format. In addition to any system functions you may use, you might consider the following functions: A function that allows the student to enter their name. A function that gets two random numbers, anywhere from 1 to 500. A function that displays the equation and asks the user to enter their answer. A function that checks to see if the answer is correct and accumulates the number correct. A function that calculates the…Write a program that reads from the user a character ('q' or 'c'). 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 character10-6. Addition: One common problem when prompting for numerical input occurs when people provide text instead of numbers. When you try to convert the input to an int, you’ll get a ValueError. Write a program that prompts for two numbers. Add them together and print the result. Catch the ValueError if either input value is not a number, and print a friendly error message. Test your program by entering two numbers and then by entering some text instead of a number. 10-7. Addition Calculator: Wrap your code from 10-6 in a while loop so the user can continue entering numbers even if they make a mistake and enter text instead of a number.

Write a program that prompts for and reads the user's first and last name (separately). Then print a string composed of the first letter of the user's first name, followed by the first five characters of the user's last name, followed by a random number in the range 10 to 99. Assume that the name is at least five letters long. Similar algorithms are sometimes used to generate user names for new computer accounts. wwwWrite a program that generates a plate number based on the user's answer to the following questions: 1. What is your favorite color of the rainbow (ROYGVIB)? a. Use the first letter of the chosen color as the first character of the plate number. b. Display "Invalid Input" and ask the user to re-enter his/her answer if the answer is not a valid color of the rainbow. 2. What is your month of birth? a. Use the last letter of the month as the second character of the plate number. b. Display "Invalid Input" and ask the user to re-enter his/her answer if the answer is not a valid month. 3. What is your first name? a. Use the third letter of the first name as the third character of the plate number. No need to include the second name if you have a second name. Make sure to use "cout" and "cin" to collect the necessary inputs from the user. For the number section: 1. Ask the user his/her age and use the age as the first and second digits of the plate number. a. Display "Invalid Input" and ask…
