Students have asked these similar questions
1. (Functions with Loop and Branches)
Write a C program that uses the function, PrintShampoo Instructions(), with int parameter
numCycles, and void return type.
If numCycles is less than 1, print "Too few.".
Else If more than 4, print "Too many.".
Else, print "N: Lather and rinse." for numCycles times, where N is the cycle number,
followed by "Done.". End with a new line. [hint: use "for" loop from 1 to numCycles
times to get desired display]
Example output with input 0: Too few
Example output with input 5: Too many
Example output with input 4:
1: Lather and rinse.
2: Lather and rinse.
3: Lather and rinse.
4: Lather and rinse.
Done.
#include
/* Your user-defined function goes here */
int main(void) {
int user Cycles;
scanf("%d", &userCycles);
PrintShampoo Instructions (user Cycles);
return 0;
}
2. (Functions with C string parameters)
Write a program in C that uses the function, MakeSentenceExcited() to replace any period (full
stop or comma) with an exclamation point.
If the input string is: I told my computer I needed a break. It replied "I am sorry, I'm not
programmed for that function."
The output will be:
I told my computer I needed a break! It replied "I am sorry! I'm not programmed for that
function!"
Assign a string size of 200 or above. Use "fgets()" to take the string input. Don't forget to
include the string header file.
Hint: A very similar example 3 problem is given in the lab slide. Try to follow that example.
• Population of a town today is 10000. The population has decreased steadily at the rate of
1% per year for last 10 years. Write a program to determine the population at the end of each
year in the last decade. (Solve it with C program in Code Block).
Comment/Discussion on the obtained results and discrepancies (if any).

Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight. Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart: When does the worker typically take lunch? Did the worker do work on the weekend? On which weekday did the worker start working on their computer at the latest hour? cpu_usage = [ [2, 2, 4, 2, 4, 1, 1, 4, 4, 12, 22, 23, 45, 9, 33, 56, 23, 40, 21, 6, 6, 2, 2, 3], # Monday [1, 2, 3, 2, 3, 2, 3, 2, 7, 22, 45, 44, 33, 9, 23, 19, 33, 56, 12, 2, 3, 1, 2, 2], # Tuesday [2, 3, 1, 2, 4, 4, 2, 2, 1, 2, 5, 31, 54, 7, 6, 34, 68, 34, 49, 6, 6, 2, 2, 3], # Wednesday [1, 2, 3, 2, 4, 1, 2, 4, 1, 17, 24, 18, 41, 3, 44, 42, 12, 36, 41, 2, 2, 4, 2, 4], # Thursday [4, 1, 2, 2, 3, 2, 5, 1, 2, 12, 33, 27, 43, 8,…arrow_forward
- (Rounding Numbers) Function floor can be used to round a number to a specific decimal place. The statementy = floor(x * 10 + 0.5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor(x * 100 + 0.5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines fourfunctions to round a number x in various ways:A. roundToInteger(number)B. roundToTenths(number)C. roundToHundredths(number)D. roundToThousandths(number)For each value read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth and the number rounded to the nearest thousandth.arrow_forward(Python) Without giving me the code, can you give me some advice or tips on approaching this?arrow_forwardProblem 4.

- (C PROGRAMMING ONLY!) 6. Teaching the Dog To Sitby CodeChum Admin Ever since I was a kid, I've always wanted to see a dog sit because it's so cute ? Let's create a function that lets a dog sit! Instructions: In the code editor, you are provided with the definition of a struct Dog. This struct needs an integer value for its age. Furthermore, in the main, a Dog is already created for you and is passed to a call to a function, sit().Your task is to declare and define the function sit() which has the following details:Return type - voidName - sitParameters - 1 DogDescription - prints the message, "Arf arf! My age is <AGE_OF_DOG> and I know how to sit!"Input 1. The age of the Dog Output Enter age of Dog: 3Arf arf! My age is 3 and I know how to sit!arrow_forward(Q1)This is a Data Structures problem and the programming language used is Lisp. Solve the question we detailed steps and make it concise and easy to understand. Please and thank you.arrow_forwardQ2) (Perfect Numbers) An integer number is said to be a perfect number if its factors, including 1 (but not the number itself), sum to the number. For example, 6 is a perfect number because 6 = 1 + 2 + 3. Write a function perfect that determines if parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1 and 1000. Print the factors of each perfect number to confirm that the number is indeed perfect. Challenge the power of your computer by testing numbers much larger than 1000.arrow_forward
