Concept explainers
A)
C-String:
In C++, a declaration of an array of “char” is usually referred as “C-string”; but an array of “char” is not a C-string by itself.
- An effective C-string needs an occurrence of a terminating null character “\0”.
- No header file has required to make a C string because “char” is a built data type. Therefore, “<cstring>” file contains several functions that work on C string.
Example:
Consider the below declaration of C string variable:
Char student_name[10];
- Here the data type “char” is defined first and it is followed by the variable name “student_name”.
- The “[10]” is referred as “size declarator”. It indicates how many characters it can hold in memory cells.
Given string definition:
//definition of C-string
char name[20];

- 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…arrow_forwardIf a program contains the definition char name[20];indicate whether each of the following lettered program statements is legal or illegal.

- # Question 4def costume_rating(costume_color, bling_value): """ Returns a function that calculates the number of candies to return based on the costume color, bling value, and phrase length. Args: costume_color (str): The color of your costume. Must be one of 'blue', 'red', 'green', 'yellow', 'purple', or 'orange'. bling_value (int): Represents how shiny your costume is. Must be a positive integer. Returns: A function that takes in one parameter: phrase (str): The phrase said by the trick-or-treater. >>> costume_rater = costume_rating('blue', 5) >>> costume_rater('19 Character Phrase') 85 >>> costume_rater('e') 0 >>> costume_rater('seven c') 1 >>> costume_rater = costume_rating('orange', 8) >>> costume_rater('hello i want candy') 14 >>> costume_rater = costume_rating('yellow', 5) >>> costume_rater('please give me…arrow_forwardFat Percentage Calculator Develop a C# application that allows the user to calculate the fat of his daily food. The user should enter: • The total number of calories for a food item • The number of fat grams in that food item Accordingly, the application will calculate and display: • The number of calories from fat • The percentage of calories that come from fat Additionally, the applications categorizes if the food is considered low fat, normal fat, or high fat as the following rule. If the calories from fat are less than 30% of the total calories of the food, the food is considered low fat. If the calories from fat are between 30% and 40% of the total calories of the food, the food is considered normal fat. If the calories from fat are more than 40% of the total calories of the food, the food is considered high fat. Note: Make sure the number of calories and fat grams are not less than 0. Also, the number of calories from fat cannot be greater than the total number of calories. If…arrow_forwardC#arrow_forward
