Chapter 5, Problem 1MC
A group of statements that exist within a
a. block
b. parameter
c. function
d. expression
Expert Solution & Answer
Program Description Answer
A function is a group of statements that are present in a program in order to perform specific tasks.
Hence, the correct answer is option “C”.
Explanation of Solution
Function:
- A function is a group of statements that are present in a program in order to perform specific tasks.
- A function is used to reduce complexity of a program. Instead of writing a large complex program, it can be divided into small chunks, each one performing a particular part of the task.
- The approach of dividing a program into smaller chunks is called as “divide and conquer” because a large program is divided into smaller tasks that can be easily performed.
- A function is also called as module.
- A single program contains more than one function.
Syntax:
In Python, a function is written as follows:
#Function name
def function_Name(parameters):
#statements
Explanation for incorrect options:
A block is a piece of program which is executed as a unit in a function.
Hence, option “A” is wrong.
A parameter is a part of the program where the information is sent from one function to other function.
Hence, option “B” is wrong.
An expression contains operators, operands, and values in a combined form and they are evaluated.
Hence, option “D” is wrong.

(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.

You buy an international calling card to India. The calling card company has some special offers.
If you charge your card with $15 or $20, you don't get anything extra.
For a $35 charge, you get $6 of extra phone time.
For a $60 charge, you get $7 of extra phone time.
For a $120 charge, you get $15 of extra phone time.
Write a function that asks the user for the amount he/she wants on the card and returns the total charge that the user gets.
Note: Values other than those mentioned earlier are not allowed.
Include appropriate comments to make your code more readable.

- Hi! I need assistance writing the PSEUDOCODE and the SOURCE CODE for the problem listed below! Any help is appreciated, thank you! program5_3.pyWrite a program about triangles. You need two files, a module file and an executable file with a main method.The module file (defines two functions): One function that takes the three sides of a triangle as arguments. It returns True if the sides define a right triangle and False if it doesn't. HINT: This is easiest with a Math module function. The other function must use Heron's Formula to calculate and return the area of a triangle. Learn about Heron's formula online. The main file:Prompt the user to enter the three sides (longest first) of the triangle. Use integers only. Make sure that no side is longer than the sum of the other two sides. Call the function that returns a boolean and use it to output whether the triangle is a right triangle, or not. Call the function that returns the area.

- # Python 3 def printFunction(num1, num2): num3 = num1 + num2 return num3print(num3) Explanation: Here, num3 is the local variable that is defined in the scope of the function and when it is used outside the function, an error occurs. Print(num3) is the statement which is outside the scope of the function. So, when this statement is executed, there is no variable named num3 to be printed, so it gives an error. The error that occurs is : NameError: name 'num3' is not defined Construct a function that takes an argument. Give the function parameter a unique name. Show what happens when you try to use that parameter name outside the function. Explain the results. Show what happens when a variable defined outside a function has the same name as a local variable inside a function. Explain what happens to the value of each variable as the program runs.arrow_forwardIN PYTHON PLEASE AND FLOWCHART DRAWING COMPUTERIZED PLEASE!! In many businesses across the country, people are buying food and goods using cash. Whenever a purchase is made with cash, it is usual that change must be back to the customer. Business point of sales software help to ensure that the correct change is return to a customer by providing detailed information of the change that should be returned to the customer. using the fewest number of bills and coins. In this assignment, you are asked to design and implement a program that writes out what bills (ones, fives, tens, twenties) and coins (pennies, nickels, dimes, and quarters) that should be returned to the customer given two inputs from the user: A total cost of a sale. The amount that was paid by the customer. Ensure that your output is grammatically correct. If the customer does not provide adequate payment, you should print the following statement, the program should end.

For example, if an acre of land is valued at $10,000, its assessment value is $6,000. The property tax is then 72¢ for each $100 of the assessment value. The tax for the acre assessed at $6,000 will be $38.40. Write a function that accepts the actual value of a piece of property and displays the assessment value and property tax.

- Design and implement an application that reads an integer value representing a year from the user. The purpose of the program is to determine whether the year is a leap year (and therefore has 29 days in February) in the Gregorian calendar. A year is a leap year if it is divisible by 4, unless it is also divisible by 100 but not 400. For example, the year 2003 is not a leap year, but 2004 is. The year 1900 is not a leap year because it is divisible by 100, but the year 2000 is a leap year because even though it is divisible by 100, it is also divisible by 400.

The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }arrow_forward
