Question 1
Write a program to simulate hand-held electronic calculator. Your program should execute as follows:
• Step 1: display a prompt and wait for the user to enter an instruction code (a single character):
‘+’ for addition
‘-‘ for subtraction
‘*’ for multiplication
‘/’ for division
‘p’ for power
‘c’ to clear the current accumulator
‘s’ for square root
‘l’ for log
‘n’ for ln
‘q’ for quit
• Step 2: (if needed) display a prompt and wait for the user to enter a type float number (which we will call left-operand)
• Step 3: (if needed) display a prompt and wait for the user to enter a type float number (which we will call right-operand)
• Step 4: display the accumulated result at any point during processing and repeat steps 1 through 3 using a GOTO statement (no loops in this assignment).
Use a separate function enter_code to prompt the user for instruction code and to ensure that a valid code is entered. Also, use a separate function enter_operand for the entry of the left-operand and the right-operand. Finally, use another function compute to perform the indicated operation. (unless q was entered).
Question 3A Baby Sitting Problem: A baby sitter charges $1.50 per hour until 9:00 pm (while the kids are still up), $1.00 per hour between 9:00 pm and midnight, and $1.25 per hour after midnight (since late night baby sitting interferes with morning classes).
Write a program that reads the sitter's starting time in hours and minutes and the ending time in hours and minutes and then computes the sitter's fee. Assume all times are between 6:00 pm and 6:00 am; hours should be entered as numbers on a 12-hour clock, so that hour 3 should be considered as 3:00 am and hour 8 should be considered as 8:00 pm. Hours outside the range 1 to 12 should be considered invalid.
[Note: You may not use a 24 hour clock for this problem. Also, times must be given in hours and minutes (as two nonnegative integer values).]
Question 4Write a program to get a date from the user in the format day/month/year. Tip: use extra variables to read the /. The program should check the three parts of the date (day, month, year), and print a warning message for any part of the date that is wrong. If the whole date is correct, it should print a message saying that the date is valid. The normal rules for dates apply: valid days are from 1 to 28, 29, 30, or 31 (depending on the month and on whether the year is a leap year. You might want to use a switch statement to perform this task.); valid months are from 1 to 12; valid years start from 1582 (the year in which our current calendar system started). The rule for deciding if a year is a leap year is as follows: a year evenly divisible by 4 is a leap year; except if the year is evenly divisible by 100, in which case it is not a leap year; except if the year is evenly divisible by 400, in which case it is a leap year.
Examples:
./date_check
Enter a date (d/m/y): 29/2/2002
The day 29 is not valid!
./date_check
Enter a date (d/m/y): 32/15/1002
The year 1002 is not valid!
The month 15 is not valid!
The day 32 is not valid!
./date_check
Enter a date (d/m/y): 20/9/2002
The given date is valid.
