C++ programming question:
Suppose we have just discovered an alien planet (we will call it Mars), and on this planet one year is divided into 15 months and each month consists of 30 days.
i. Write the code for a struct charontime to hold years, months, and days for time on Charon -all ints.
ii. Write a function that takes an int parameter that represents the number of Charon days, converts it to years, months, and days on Charon and returns this information in a struct charontime. So for example it will convert 800 days into a struct that represents 1 year, 11 months, and 20 days.
iii. Write a function that takes a struct charontime parameter and returns the total number of Charon days represented by the struct.
iv. Write a function that takes a filename and an array of struct charontime, opens the file, reads each line as the number of Charon days, converts this to a struct charontime and stores this in the array. (you don't need to create an actual file with number of days in it...…

- Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls.

Declare a variable of type fruitType to store the following data: Fruit name—banana, color—yellow, fat—1, sugar—15, carbohydrate—22. Write a C++ function, getFruitInput to get and store data into a variable of fruitType. Write a C++ function, printFruitInfo to output data stored into a variable of fruitType.
