- Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs Yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: Yes Ex: If the input is: 42,000 or 1995! the output is: No Hint: Use a loop and the Character.isDigit() function.Which for statement repeats for all positive four-digit integers in decreasing order? I.e.: the for loop will repeat for 9999, 9998, 9997, ..., 1000. Select one: a. for (int j = 9999; j > 1000; j--) b. for (int j = 1000; j 999; j--) e. None of the othersIn Java A while loop reads integers from input. Write an expression that executes the while loop until a positive integer is read from input. Ex: If the input is -20 -43 -25 -22 15, then the output is:User entered -20User entered -43User entered -25User entered -22Loop terminated while () {
- Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. You may assume that the string does not contain spaces and will always contain less than 50 characters. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the isdigit() function (don't forget to include the ctype library). please use c programming language1. Write a program that reads an integer from the user. Then your program should display a message indicating whether the integer is even or odd. 2. A string is a palindrome if it is identical forward and backward. For example "anna","civic","leveľ"and“hannah"are all examples of palindromic words. Write a program that reads a string from the user and uses a loop to determines whether or not it is a palindrome. 3. Write a program that reads integers from the user and stores them in a list. Yourprogram should continue reading values until the user enters 0. Then it should display all of the values entered by the user (except for the 0) in order from smallest to largest,with one value appearing on each line. 4. Two words are anagrams if they contain all of the same letters, but in a differentorder. For example, "evil" and “live" are anagrams because each contains one 'e', one 'i', one l', and one 'v'. Create a program that reads two strings from the user, determines whether or not they…1. Write a program that reads an integer from the user.

- 3. Write a program that deliberately contains an endless or infinite while loop. The loop should generate multiplication questions with single digit random integers. Users can answer the questions and get immediate feedback. After each question, the user should be able to stop the questions and get an overall result. See Example Output. Example Output What is 7 * 6 ? 42 Correct. Nice work! Want more questions y or n ? y What is 8 * 5 ? 40 Correct. Nice work! Want more questions y or n ? y What is 5 * 5 ? 25 Correct. Nice work! Want more questions y or n ? y What is 8 * 9 ? 66 Incorrect.

Daniel Liang Publisher: Pearson ISBN: 9780134670942write this in pseudocode #4 – In pseudocode, write a for-loop that decreases from 100 to 2 by 2s. Inside the loop, print the value of the loop variable unless the value is from 60 to 80 (inclusive). Use only 1 if-statement. Do NOT write Python code! Write your answer below: #5 – Review the decision structure given below. If myAnswer > 20 Then myAnswer = myAnswer - 25Else If myAnswer <= 5 Then If myAnswer < 0 Then myAnswer = 10 If myAnswer < 3 Then myAnswer += 10 Else myAnswer += 1Else myAnswer = 9 If myAnswer < 10 ThenmyAnswer += 1 Display myAnswer What are the results displayed when the decision structure above executes for each given value below:If myAnswer = 6 then myAnswer = myAnswer = 15 then myAnswer = myAnswer = 30 then myAnswer = myAnswer = 2 then myAnswer = myAnswer = -1 then myAnswer = #6 – 2-dimensional arrays can be thought of as containing rows…Construct a while() loop in programming language c, which prints only the even integer numbers in the range n downto 2. Where n is an integer entered by the user. You may assume that n > 1. Show all variable declarations and the prompt for n, along with the appropriate loop. If n is 7, then the output should look like: 6 4 2
- 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.QuadraticAA.java Write a program that solves quadratic equations of the form , where The values A, B, and C will be real numbers (doubles) that you will request from the user. The equation below is what is used to solve for . Remember, there will be two solutions for x (not necessarily distinct). No loops are necessary, so don’t include any. To find the two solutions for this equation, you will use the quadratic formula: Remember that it must be solved for both the and : You will ask the user to input a value for A, B, and C (in that order, using those same letters), then you will use those values to find the two values of x as above. Your output MUST then display the original quadratic equation back to the user with their coefficients in place, and then output the two results. We will assume that the user will not put zero for A. *Format ALL OUTPUT VALUES (including the equation) to have only two decimal places. There is a test case below. Your program should run the…Accumulating Totals in a Loop Summary In this lab, you add a loop and the statements that make up the loop body to a Java program that is provided. When completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. Your loop should execute until the user enters the character X instead of L for left-handed or R for right-handed. The inputs for this program are as follows: R, R, R, L, L, L, R, L, R, R, L, X Variables have been declared for you, and the input and output statements have been written. Instructions Ensure the file named LeftOrRight.java is open. Write a loop and a loop body that allows you to calculate a total of left-handed and right-handed people in your class. Execute the program by clicking Run and using the data listed above and verify that the output is correct.
