Assignment 5: Long-Distance Calls
This is an individual assignment to be done by each student.
Here is the problem specification:
A long-distance carrier charges the following rates for telephone calls:
Starting Time of CallRate per Minute
00:00-06:59 |
0.12 |
07:00-19:00 |
0.55 |
19:01-23:59 |
0.35 |
Write a program that asks for the starting time and the number of minutes of the call, and display the charges. The program should ask for the time to be entered as a floating-point number in the form HH.MM. For example, 07:00 hours will be entered as 07.00, and 16:28 hours will be entered as 16.28.
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 be accepted. Hint: Assuming num is a floating-point variable, the following expression will give you its fractional part: num - static_cast<int>(num).
- Create an IPO chart.
- Plan the algorithm using pseudocode.
- Save it in a filename LastFirst_a5.doc (e.g. DoeJohn_a5.doc)
- Save the C++ program in LastFirst_a5.cpp (e.g. DoeJohn_a5.cpp). Include your name and comments in the program.
- Compile and run the program.
- Take a screen shot of the output. Append it in LastFirst_a5.doc.
Assignment 6: Calculator
This is an individual assignment to be done by each student.
Here is the problem specification:
Write a program that adds, subtracts, multiplies, or divides two integers. The program will need to get a letter (A for addition, S for subtraction, M for multiplication, or D for division) and two integers from the user. If the user enters an invalid letter, the program should not ask the user for the two integers. Instead, it should display an appropriate error message before the program ends. If the letter is A (or a), the program should calculate and display the sum of both integers. If the letter is S (or s), the program should display the difference between both integers. When calculating the difference, always subtract the smaller number from the larger one. If the letter is M (or m), the program should display the product of both integers. If the letter is D (or d), the program should divide both integers, always dividing the larger number by the smaller one.
Use the followinmg test data:
Operation First integer Second integer
A 10 20
a 45 15
S 65 50
s 7 13
G
M 10 20
d 45 15
d 50 100
- Create an IPO chart. List the input, processing, and output items.
- Plan the algorithm using pseudocode.
- Save it in a filename LastFirst_a6.doc (e.g. DoeJohn_a6.doc)
- Enter your C++ instructions into a source file named LastFirst_a6.cpp (e.g. DoeJohn_a6.cpp). Include your name and comments in the program.
- Compile and run the program.
- Take a screen shot of the output. Append it in LastFirst_a6.doc.
