PLEASE ANSWER IN C
Assume that an int variable age has been declared and already given a value and assume that a char variable choice has been declared as well. Assume further that the user has just been presented with the following menu:
(Yes, this menu really IS a menu!)
Write some code that reads a single character (S or T or B) into choice. Then the code prints out a recommended accompanying drink as follows:
If the value of age is 21 or lower, the recommendation is "vegetable juice" for steak, "cranberry juice" for trout, and "soda" for the burger. Otherwise, the recommendations are "cabernet", "chardonnay", and "IPA" for steak, trout, and burger respectively. Regardless of the value of age, your code should print "invalid menu selection" if the character read into choice was not S or T or B.

Write a Loop class. The contents of a loop object are represented internally as a simple python list with the following additional instance variables:
loop - a python list containing the elements of the loop list
head - which stores the index of the first element of the loop list
current - which stores the index of the last element of the loop list
size - which stores how many actual elements are in the loop
max - which stores the max number of elements that can be in a loop
Note that current and head will be the same when the list is empty, and when the list contains a single element.
And methods:
__init__(self, max) - which constructs an empty loop object;
__str__(self) - which returns a string representing the loop object as described below;
add(element) - which adds the element to the end of the loop (i.e. at the position of current + 1)
empty() - which says whether there are any elements in the loop;
count() - which says how many elements currently are in the loop;
delete() - which returns the first item from the loop (i.e. at the position of head) and removes it from the loop;
max() - returns the max number of elements allowed in the loop.
__init__ initializes the empty locations in the loop list to None. Assume that max is always greater than the number of elements to be in the loop at any one time. When an element is being added to an empty loop, it always goes into the first location (index 0) in the loop list and head and current are reset to 0.
If an attempt is made to delete() from an empty loop then delete() returns None. When an element is deleted from the loop its value is changed to None. Remember, your code needs to properly maintain the correct values of loop, head, current and size.
__str__ formats the loop object data as follows:
<max> <size> <head> <current> <loop list>
For example, after:
x = Loop(4)
x.add(1)
x.add(3)
x.delete()
print(x)
"print(x)" prints out:
4 1 1 1 [None, 3, None, None]
For example:
| Test | Result |
|---|---|
x = Loop(5) print(x) |
5 0 0 0 [None, None, None, None, None] |
x = Loop(5) x.add(3) print(x) |
5 1 0 0 [3, None, None, None, None] |
x = Loop(3) x.add(3) x.add(2) print(x) |
3 2 0 1 [3, 2, None] |
x = Loop(3) x.add(3) x.add(2) x.delete() print(x) |
3 1 1 1 [None, 2, None] |
x = Loop(3) x.add(2) x.add(5) x.add(3) x.delete() x.add(7) print(x) |
3 3 1 0 [7, 5, 3] |

IN C ++ PLEASE CODE FOR BUBBLE SORT---Add code to sort the bowlers. You have to sort their parallel data also. Print the sorted bowlers and all their info .
You can use a bubble sort or a shell sort. Make sure to adjust your code depending on whether or not you put data starting in row zero or row one.
Sort by Average across, lowest to highest. The highest average should then be on the last row..
When you sort the average, you also have to move the names and scores, this is the reason you can't use a built-in sort.
Names score1 score2 score3 average score

Write a C program that prints the Grade of each student in a class based on their mark. The program must also print the average mark of the class.
The program must prompt (ask) the user for the mark of a student (out of 100).
The program must then print the mark entered and the grade received based on the table below.
|
Grade |
Range |
|
A |
85 to 100 inclusive |
|
B |
75 to 85 inclusive |
|
C |
60 to 70 inclusive |
|
D |
50 to 60 inclusive |
|
F |
Less than 50 |
For example “The student mark is 87 and their grade is A.”
This must be done repeatedly until a mark of -1 is entered.
The average mark of all of the class must then be shown.
For Example “The average mark of the class is 34.23.”
Note: To calculate the average, you must add up (total) all of the marks and then divide by the number of students (number of marks entered)
