Long-Distance Calls
A long-distance carrier charges the following rates for telephone calls:
Starting Time of Call | Rate per Minute |
00:00-06:59 | 0.05 |
07:00-19:00 | 0.45 |
19:01-23:59 | 0.20 |
Write a
Input Validation: The program should not accept times that are greater than 23:59. Also, no number whose last two digits are greater than 59 should he accepted. Hint: Assuming num is a floating-point variable, the following expression will give you its fractional part:
num - static_cast<int>(num)

- use C++ programming language Write a program that computes and displays the charges for a patient’s hospital stay. First, the program should ask if the patient was admitted as an inpatient or an outpatient. If the patient was an inpatient, the following data should be entered: The number of days spent in the hospital The daily rate Charges for hospital services (lab tests, etc.) Hospital medication charges If the patient was an outpatient, the following data should be entered: Charges for hospital services (lab tests, etc.) Hospital medication charges Use a single, separate function to validate that no input is less than zero. If it is, it should be reentered before being returned. Once the required data has been input and validated, the program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the inpatient data, while the other function accepts arguments for outpatient data. Both functions should return the…arrow_forwardThis standard library function returns a random floating-point number within a specified range of values.a. randomb. randintc. random_integerd. uniformarrow_forwardMobile Service Provider Write a flowgorithm program that will calculate a person’s mobile phone bill based on plan chosen and the data used.

- PROBLEM: Write a program that prompts the user to input the amount of money that an ATM machine will dispense and then show the breakdown of how many 1000, 500, and 100 peso bill/s are dispensed. The program must display the amount then prompt the user if the transaction will continue or not by choosing between Y (for Yes) and N (for No). If an invalid character is entered, it must display that the user entered an invalid character. The program must also display that the maximum allowable amount is 10,000 and the minimum allowable amount is 100. If the entered amount is greater than 10,000 or less than 100, an error notification must be displayed. Moreover, the entered amount must be exactly divisible by 100. SPECIFICATIONS: - You may only use the codes that we studied under our lectures All lines of codes should have a comment. - Save your cpp file as Surname - PE (Example: Pangaliman - PE.cpp) TEST CASES: If a user inputs an amount less than or equal to 10,000: REMINDER: Maximum…arrow_forwardPROBLEM:Write a program that prompts the user to input the amount of money that an ATM machine will dispense and then show the breakdown of how many 1000, 500, and 100 peso bill/s are dispensed.

The students attend college five days a week. Input values are the student's name, number, and the time in and time out for each day of the week (i.e. five different times in and times out must be input). If a student attends college more than 36 hours in a week, a congratulatory message is printed. If a student attends college less than 30 hours in a week, a warning message is printed. The output for each student is the name, hours, and the appropriate attendance message. Processing continues until a student number of zero is input. Assume that students always check in and out on the hour. Therefore, timeln and timeOut will be integer variables (i.e. they represent whole hours, and minutes are ignored).arrow_forward
- Box Office: A movie theater only keeps a percentage (20%) of the revenue earned from ticket sales. The remainder goes to the movie distributor. Write a program that calculates a theater’s gross and net box office profit for a night. The program should ask for the name of the movie, and how many adult and child tickets were sold. (The price of an adult ticket is $10.00 and a child’s ticket is $6.00.) Input: the name of the movie, number of adult tickets sold, number of child tickets sold Output: as specified below Object: cin, cout, getline, format output Note: 1. Movie names contain spaces 2, the report is aligned. 3. The decimal number is displayed with 2 decimal places.arrow_forwardThe company discounted used cars pays their employees according to this chart: 250$ per months plus 50$ per car sold. If the salesman sells more than 10 cars, the employee receives a bonus of 5% of the total of his sales, in addition to his regular salary.Each month, the owner sits in front of the computer, and enters the following information: The name of the employee, the number of cars sold, as well as the total of all the sales for the month. algorithm that will calculate the salary of an employee for the month, and then display on the screen, his name, total cars sold, base salary, bonus if applicable and entire salaryarrow_forwardFox International sells pre-paid calling card with the following features: Calls to USo 1.2 cents per minute plus a 49 cent connection fee per call Calls to Europeo 2.3 cents per minute plus a 49 cent connection fee per call Calls to Australiao 6.4 cents per minutes plus a 49 cent connection fee per callWrite a program that work out the charges for the month.

- C++ coding help Write a program that prompts the user for a positive integer, the first term in a hailstone sequence, and then generates a subsequence from that hailstone number to the next occurrence of 1 in the sequence. The program should also determine and display the sum and length of the subsequence. If the user enters an integer less than 1, the program should display an error message as shown in the sample run. In order for the program to handle large integers, use long rather than int when declaring them.arrow_forwardThe date June 10, 1960, is special because when we write it in the following format, the month times the day equals the year: 6/10/60 Write a program that ask the user to enter a month in numeric format, a day and a two-digit year. The program should then determine whether the month times the day is equal to the year. If so, it should display a message saying the date is Magic. Otherwise, it should display a message saying the date is not Magic. Output should look as shown below. Create test data and place in a file. Name the code file Last Name + First Initial + "-MagicDates.s", for example "SmithJ- MagicDates.s". Name the test data file in a similar manner. Upload the program and test data files to the Dropbox. 6/10/60 is Magic! 6/10/70 is not Magic. 2/11/22 is Magic!arrow_forwardProblem: Feed Nibble Monster Till Full Write a program that generates a number in [0, 500] at the beginning -- this corresponds to how hungry the monster is -- and keeps asking the user to feed the monster until that number falls to zero. Each time the user feeds the monster a nibble, hunger decreases by the decimal value of the character (i.e. if the user feeds 'A' hunger decreases by 65). But when the user feeds the monster some character that isn't a nibble, the hunger increases by the decimal value of the character (since puking depletes energy). Use while loop. Sample runs: Notice the loop exits after one iteration, because hunger was very low and one nibble made the monster full: Notice hunger increasing after non-nibble (pink highlight): Notice that the program just keeps going when the user feeds the monster only non-nibbles. Do you think the program will keep running forever if the user never gives the monster nibbles?arrow_forward
