- Time CalculatorWrite a program that asks the user to enter a number of seconds.-There are 60 seconds in a minute. If the number of seconds entered by the user is greater than or equal to 60, the program should display the number of minutes and leftover seconds in that many seconds.-There are 3,600 seconds in an hour. If the number of seconds entered by the user is greater than or equal to 3,600, the program should display the number of hours, minutes, and leftover seconds in that many seconds.-There are 86,400 seconds in a day. If the number of seconds entered by the user is greater than or equal to 86,400, the program should display the number of days, hours, minutes, and leftover seconds in that many seconds.arrow_forwardTrue or False: You cannot change the value of a variable whose declaration uses the final keyword.arrow_forward.Design Windows form application which will ask the user to input a number.

- True or False An enum declaration can only appear inside the application’s namespace.arrow_forwardC# (Temperature Conversions) Write a temperature conversion program that converts from Fahrenheit to Celsius. The Fahrenheit temperature should be entered from the keyboard (via a TextBox). A Label should be used to display the converted temperature. Use the following formula for the conversion: Celsius=(5/9)×(Fahrenheit−32)arrow_forward2. Rolling Dice Simulator in C Difficulty: Requirements: • As the title suggests, this question involves writing a program that simulates rolling dice. When the program runs, it will randomly choose a number between 1 and 6. (Or whatever other integer you prefer — the number of sides on the die is up to you.) • The program will print what that number is. • It should then ask you if you’d like to roll again. • For this question, you will need to set the min and max number that your dice can produce. For the average die, that means a minimum of 1 and a maximum of 6. . Use online C compiler HD to do this question, use while loop to get this done . In 150 words explain your code or program.arrow_forward
- The term _________________ refers to the part of the program that has access to a variable.arrow_forwardFill in the blanks: Q. User __________________ Control is Better known as _______________.arrow_forwardNO COPY PASTE PLZ The first executable statement in the program is a printf, requesting the user to enter an integer number. This is known as "prompt message" and appears on the screen like Enter an integer number As soon as the user types in an integer number, the computer proceeds to compare the value with 100. If the value typed in is less than 100, then a message Your number is smaller than 100 is printed on the screen. Otherwise, the message Your number contains more than two digits is printed.arrow_forward
- (Fraction calculator) | Write a program that lets the user perform arithmetic operations on fractions. Fractions are of the form a/b, in which _a_ and _b_ are integers and b ≠ 0. Your program must be menu driven, allowing the user to select the operation (+, –, *, or /) and input the numerator and denominator of each fraction. Furthermore, your program must consist of at least the following functions: Function menu: This function informs the user about the program’s purpose, explains how to enter data, and allows the user to select the operation. Function addFractions: This function takes as input four integers representing the numerators and denominators of two fractions, adds the fractions, and returns the numerator and denominator of the result. (Notice that this function has a total of six parameters.) Function subtractFractions: This function takes as input four integers representing the numerators and denominators of two fractions, subtracts the fractions, and returns the…arrow_forward2. Class Exam Results Create a python program that allows a professor to input test results, and calculate the average and high score. The professor is not sure how many students took the exam that day, so you'll need to use a loop that iterates until the professor indicates there are no more students to enter. Include field validation logic to ensure the professor has entered valid test scores. You'll need an accumulator and counter variable to calculate the average. To determine the high, you'll need a variable that stores the current high score as you're iterating thru all the students' results. If a given student's score is higher than the current high score, that becomes the new high score. Initialize the high score to a 0 so the first student's score is automatically higher. Once the loop has ended, you've got all the information you need to print the class average, number of students and the high exam score.arrow_forward#3 – This pseudocode has multiple problems. Fix the calling statement and the definition below so that the routine accepts 3 grades as parameters and returns the average into a variable.
