Concept explainers
Convert the following if/else if statement into a switch statement:
if (choice== 1)
cout <<fixed<< showpoint << setprecision(2);
else if ((choice== 2) || (choice== 3))
cout << fixed << showpoint << setprecision(4);
else if (choice== 4)
cout << fixed << showpoint << setprecision(6);
else
cout << fixed << showpoint << setprecision(8);

- Serendipity Booksellers has a book club that awards points to its customers based on the number of books purchased each month. The points are awarded as follows: If a customer purchases no books, he or she earns 0 points If a customer purchases 1 through 5 books, he or she earns 5 points for each book. If a customer purchases 6 through 10 books, he or she earns 10 points for each book. If a customer purchases 11 or more books, he or she earns points equal to 20 points for each book. (Use Python) Use the Design Recipe to write the function customer_rewards which consumes the number of books purchased, and returns the total points. Include a docstring! Write 3 assert_equal statements to test your function.arrow_forwardLab: switch Note: switch syntax is only applied for service selection. You can use if – else syntax for other comparison. Using switch syntax to write a program that calculates and prints the bill for a cellular telephone company. The company offers two types of service: regular and premium. Its rates vary, depending on the type of service. The rates are computed as follows: Regular service: $10.00 plus first 50 minutes are free. Charges for over 50 minutes are $0.20 per minutes. Premium service: $25 plus For calls made from 6:00 a.m to 6:00 p.m., the first 75 minutes are free; charges for more than 75 minutes are $0.10 per minute. For, calls made from 6:00 p.m. to 6:00 a.m., the first 100 minutes are free; charges for more than 100 minutes are $0.05 per minute. Your program should prompt the user to enter an account number, a service code (type char), and the number of minutes the service was used.

- Question text Determine whether the ff hypotheses about a computer program • There is an undeclared variable or there is a syntax error in the first five lines. • If there is a syntax error in the first five lines, then there is a missing semicolon or a variable name is misspelled. • There is not a missing semicolon. • There is not a misspelled variable name. lead to the conclusion • There is an undeclared variable. Let the following symbols represent the corresponding statements: uv - There is an undeclared variable. se - There is a syntax error in the first five lines. ms - There is a missing semicolon. vm - There is a misspelled variable name. Thus, in symbolic form, we have to show whether the argument below is valid: uv V se se → (ms V vm) ~ ms ~ VM ... uvarrow_forwardA one-way if statement performs an action if the specified condition is true.
