Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.

- Is it true or false? A string cannot be stored in a char data type variable.A program contains the following function. int cube(int num) {return num * num * num; }Write a statement that passes the value 4 to this function and assigns its return value to the variable result.Assume the following variables are defined: char ch; double interest ; string name ; Assign each variable to a value of the correct data type.
- Domino's Time Function Name: dominosTime() Parameters: N/A Returns: None Description: During the summer, you ordered a lot of food from Domino's. Pizzas are $12, an order of pasta is $6, and chicken wings are $8. Write a function that asks the user how many of each food item they would like, and then print a response telling them what their order to- tal will be. The order total should be an integer. >>> dominosTime() How many pizzas do you want? 3 How many orders of pasta do you want? 2 How many orders of chicken wings do you want? 2 By ordering 3 pizzas, 2 orders of pasta, and 2 orders of chicken wings, your order total comes to $64.The code does not run accordingly # Main function def main(): # Initialize a local variable num=0 # Get a number from the user num=int(input("Enter an integer:")) # Call the function if is_prime(num): Why is the variable named num # Print the statement print(num,"is a prime number.") else: # Print the statement print(num,"is not a prime number.") # Function definition def is_prime(number): And here it is named number # Divide the number by 2 value=int(number/2) # Assign true to a variable status=True # Loop for i in range(2,value+1): # Check if number mod i is equal to 0 if number%i==0: # Assign false to a variable status=False # Return the variable return status # Call the main() function…Question 1: break phrase Problem statement Breaking a string into two parts based on a delimiter has applications. For example, given an email address, breaking it based on the delimiter "@" gives you the two parts, the mail server's domain name and email username. Another example would be separating a phone number into the area code and the rest. Given a phrase of string and a delimiter string (shorter than the phrase but may be longer than length 1), write a C++ function named break_string to break the phrase into two parts and return the parts as a C++ std::pair object (left part goes to the "first" and right part goes to the "second"). Do the following Write your algorithm as code comments. I recommend to follow UMPIRE technique Implement your function

The program will accept 3 scores and computes the average score. Determine the grade based on the following rules: - If the average score is equal or greater than 90, the grade is A. - If the average score is greater than or equal to 70 and less than 90, the grade is B. - If the average score is greater than or equal to 50 and less than 70, the grade is C. - If the average score is less than 50, the grade is F.

- Driving costs - functions Learning Objectives Create a function to match the specifications Use floating-point value division Instructions Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print(f'{your_value:.2f}') Ex: If the input to your program is: 20.0 3.1599 the output is: The gas cost for 10 miles is $1.58 The gas cost for 50 miles is $7.90 The gas cost for 400 miles is $63.20 Your program must define and call the driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles. Ex: If the function is called with: 50 20.0 3.1599 the function returns: 7.89975 def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon) Your program should…23) Which of the following statements performs a boxing conversion?: * C C C C A) int x = 7; B) x = int(7); C) int x = new D) int amount E) int Integer (7); x.intvalue (); amount = x;""" MovieGuide.py This program allows each theater patron to enter a value from 0 to 4 indicating the number of stars that the patron awards to the Guide's featured movie of the week.
