Question
Detect Even/Odd
Write a function with no parameters, even_or_odd() in Python
Specifications:
- read an integer from standard input
- return 0 if the integer is even, 1 if the integer is odd
- do not use a conditional ("if") statement, just use modular arithmetic (such as // or %)
- do not print the result, return it
HINT: What is the remainder when you divide an even number by 2? What is the remainder when you divide an odd number by 2?
REMINDER: DO NOT use prompts in your input statements for this problem.
For example:
Test | Input | Result |
---|---|---|
ans = even_or_odd() print(ans) | 5 | 1 |
ans = even_or_odd() print(ans) | -14 | 0 |
ans = even_or_odd() print(ans) | 0 | 0 |
ans = even_or_odd() print(ans) | 99 | 1 |

- Calculate Caloric Intake Learning Objective: In this lab, you will practice Functions and test functions Lists Printing If statements Instructions: Main Idea The Basal Metabolic Rate (BMR) is the amount of energy (calories) your body needs while resting. This accounts for about 60 to 70 percent of calories burned in a day. In general, men have a higher BMR than women. One of the most accurate methods of estimating your basal metabolic rate is the Harris-Benedict formula: Adult_Male_BMR = 66 + (6.3 x bodyweight in lbs.) + (12.9 x height in inches) - (6.8 x age in years) Adult_Female_BMR = 655 + (4.3 x weight in lbs.) + (4.7 x height in inches) - (4.7 x age in years) In this lab, you will be given the function calculate_calorie_intake and you will be required to write the body of the test functions test_calculate_calorie_intake_negative, test_calculate_calorie_intake_1, test_calculate_calorie_intake_3. In these functions, you will write function calls to calculate_calorie_intake…arrow_forwardThis calls for a clarification of the differences between validation and verification.

"In swimming, a lap is the same as a length. By definition, a lap means a complete trip around a race track, in swimming, the pool is the race track. Therefore if you swim from one end to the other, you’ve completed the track and thus you’ve completed one lap or one length." (Source: What Is A Lap In Swimming? Lap Vs Length) Write the function meters_to_laps() that takes a number of meters as an argument and returns the real number of laps.

- C++ please - 24-hour time (also known in the U.S. as military time) is widely used around the world. Time is expressed as hours since midnight. The day starts at 0000, and ends at 2359. Write a program that converts am/pm time to 24-hour time. If the input is 2:30 pm, the output should be 1430. If the input is 12:01 am, the output should be 0001. Hints: Think of how each hour should be handled. 12:00 am -12:59 am becomes what? 8:00 am becomes what? 12:00 pm? 1:00 pm? Group the hours into cases that should be handled similarly (e.g., 1:00 am to 11:00 am are handled the same). Declare variables for hoursAmPm, minAmPm, and hours24. Note that minutes for 24-hour time remain the same as for am/pm, so no extra variable is needed. Use an if-else statement to detect each case, and set the hours24 appropriately. When outputting hour24, check if the hour is 0-9 (just check for < 10). If so, output a "0". So 7 will be output as 07. Do the same when outputting the minutes. #include…arrow_forward*Modify the program so that the user will error trap for only 1 and 0 as an input. *If the user enters an input other than 1 or 0 display an error message and request the user enter that input again. *Do this for all inputs in the code. # User defined function for logic OR# The function takes two parameters and returns a single intdef OR(a: int, b: int)->int:# If a is equal to 1 return 1if a == 1 :return 1# If b is equal to 1 return 1elif b == 1 :return 1# If a and b is equal to 0 return 0else :return 0 # User defined function for logic NOR# The function takes two parameters and returns a single intdef NOR(a: int, b: int)->int:# If a is equal to 0 and b is also equal to 0 return 1if a == 0 and b == 0 :return 1# If a is equal to 0 and b is equal to 1 return 0elif a == 0 and b == 1 :return 0# If a is equal to 1 and b is also equal to 0 return 0elif a == 1 and b == 0 :return 0# If a is equal to 1 and b is also equal to 1 return 0elif a == 1 and b == 1 :return 0 # User defined…arrow_forwardc not c++arrow_forward
