- Indicate whether the statement is true or false.arrow_forward*Using C# in Microsoft Visual Studio* create an application that lets the user enter a nonnegative integer and then uses a loop to calculate the factorial of that number. Display the factorial in a label or a message box. If the input is nonnumeric your program SHOULD NOT CRASH but display a message “”non numeric input”. If the input is negative display the message “”negative numbers are invalid.arrow_forward2. While Loop Write a program, using a while loop, that asks the user to enter their monthly income. The program should then prompt the user to enter their expenses for the month. The program should keep a running total. Once the user has finished entering their expenses the program should then display if the user is over or under budget. • The output should display the monthly budget, the total expenses and whether the user is over or under budget. Use a empty return (enter key) to end the loop. Name the source code file yourName_labó 2.py. Test and run the program. Capture the output console and save it as an image file named yourName_labó_output6_2.jpg. • Submit the .py and the image files through Canvas.

- Q7arrow_forward1. Ifthe initial condition of any while loop is false it will still execute once. 2. In the case of an infinite while loop, the while expression (that is, the loop condition) is always true. 3. A counter-controlled loop is used when the exact number of data entries is known. 4. The control variable in a flag-controlled while loop is an int variable. 5. A break statement is legal in a while loop, but not in a for loop. 6. Void methods have no return data type. 7. Ifa formal parameter is a variable of a primitive data type, then after copying the value of the actual parameter, there is no connection between the formal and actual parameter. 8. All the methods defined in a class must háve different names. 9. The statement int () list = new int[15); creates list to be an array of 14 components because array index starts at 0. 10. When you pass an array as a parameter, the base address of the actual array is passed to the formal parameter. 11. Members of a class are usually classified into…arrow_forwardYou need to write a loop that will repeat exactly 125 times. Which is the preferred loop construct to use? A. while B. do while loop C. for looparrow_forward
- You will write a program that calculates gas milage, also known as fuel economy. The program will use a while loop to repeatedly ask the user for the number of miles driven and gallons of gas used at their last fill up. On each iteration of the loop, your program will calculate the mileage for each fill up. The user will be able to exit the loop by pressing the enter key. After the user exits the loop, the program will print the cumulative gas mileage, by dividing the cumulative number of miles by the cumulative number of gallons. The floating point output should be printed to one decimal place of precision. Here is an example of how the program should work: Your Personal Fuel Economy Number of miles traveled (or enter to exit):380 Number of gallons needed: 12 Mileage this tank: 31.7 Number of miles traveled (or enter to exit): 235 Number of gallons needed:9 Mileage this tank: 26.1 Number of miles traveled (or enter to exit): Average mileage: 29.3arrow_forwardIn C, Write a statement that terminates the current loop when the value of the int variables x. and y are equalarrow_forwardThe while loop checks the loop-continuation-condition ______. Select one: a. First b. Last c. Continuously as the loop executes. d. Only when the loop-continuation-condition changes.arrow_forward
- True or False? In a do…while loop, the condition is checked at the bottom of the loop.arrow_forward2. Task 1: Using do-while loop Write a do-while loop which validate and evaluate the input value for variable grade. NOTE:The program will force the user to enter a valid grade.When the user enter a valid grade, the program will evaluate the grade as passing or failing grade.When the user enter an invalid grade, the program will only allow 3 invalid grade input.Valid grade is from 0 to 100 only.Passing grade is from 70 to 100.Failing grdae is from 0 to 69. NOTE:Your source code must display any of the given sample output below.It means your source code should be flexible enough to meet any of the given sample output.Your source code output must be identical to any of the given sample output.It means you have to strictly follow what are the displayed text, labels, casing of characters in the sample output. OUTPUT 1 Enter Grade: 100 Remark: Passed OUTPUT 2 Enter Grade: 69 Remark: Failed OUTPUT 3 Enter Grade: -1 Remark: Invalid Enter Grade: 101…arrow_forwardProblem 2: Safe Square Root Write a program to take the square root of a number typed in by the user. Your program should use a while-loop to ensure that the number they typed in is positive. If the number is negative, you should print out a warning “The number is negative. Try again.” and re-prompt the user to take a valid input. You can get the square root of a number n with Math.sqrt(n). Make sure you don't do this until the loop is done and you know for sure you've got a positive number. Sample input and output: Enter a number > -9 The number is negative. Try again. Enter a number > 9 The square root of 9 is 3.0 Enter a number > 2 The square root of 2 is 1.4142135623730951arrow_forward
