Write a program that allows a user to enter any number of student quiz scores, as integers, until the user enters 99. If the score entered is less than 0 or more than 10, display Score must be between 10 and 0 and do not use the score. After all the scores have been entered, display the number of valid scores entered, the highest score, the lowest score, and the arithmetic average
Write a program that prompts the user to enter five test scores and then prints the average test score. Indicate the average test score by printing it to the terminal.
Average test score is X
(Assume that the test scores are decimal numbers)
Write a program that reads from the user a number that represents its grade, and then displays a message
to tell the user if he passed the exam (if the entered grade is greater than or equal to 60) or not (if the
entered grade is less than 60).
The entered grade should be a number between 0 and 100. Otherwise, the program displays an error
message.
Sample Run:
Please enter your grade (between 0 and 100): 75
Congratulations! You have passed the exam.
Please enter your grade (between 0 and 100) : 45.5
Unfortunately... You have not passed the exam.
Please enter your grade (between 0 and 100) : 112
ERROR: You have entered a wrong grade!

Write a program that takes the x-y coordinates of a point in the Cartesian plane and prints a message telling either an axis on which the point lies or the quadrant in which it is found. If x or y is 0, the code will print out "The point is on x or y axis". For example, if your input x is 2.5, and y is 1, it will print out "The point is in Quadrant One"; if the input x is -2.3, and y is -3.2, it will print out "The point is in Quadrant Three"; if the input x is 0, and y is 20, it will print out "The point is on x or y axis ". Requirements: 1. The inputs of x and y should be float data type. 2. The input should prompt a message on the screen to ask for the input x and y.arrow_forward
- Write a program that prompts the user for a U.S. dollar amount and then converts it to Japanese Yen, British Pound, and New Zealand currency. Once you calculate the conversion, print a single line with each converted currency only showing two decimal places, and its respective code (as shown in the example below): 10 U.S. Dollars in Egyptian Pound (exchange rate = 15.9976) would print as follows after conversion: 10.00 USD in Egyptian Pound is 159.98 EGParrow_forwardWrite 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.

It displays the message “Positive!”, “Negative!” or “Zero!”.arrow_forwardWrite 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 characterarrow_forwardWrite a program that asks the user to enter 2 integers of 4 digits and displays thedifferent digits as X and * if they are the same. If the user enters a number which is notof four digits, then a convenient message is displayed.arrow_forward
- Write a program named GuessingGame that generates a random number between 1 and 10. (In other words, in the example above, min is 1 and max is 11.)
