CprogrammingDirections:Answer electronically the questions and submit them into BlackBoard Learn by the Due Date.Answer all questions and follow the rules below.Please attach one single text file (not Word or other formats) with all your answers.Do not send multiple files!I just need the answer … do not send program output, only the C source code … and again, all in one single text file.Rules:You many use your book and notesQuality, Re-usability, Maintainability, Readability, and Efficient code will be stressed in addition to correctness.Same rules and standards apply as your homework assignments (comments, headers, style, …)Use your computer to compile your code and test it outContact me if you have questions or state your assumptionsQuestions:1) Use the link below for the background needed to create two functions that work with a Trapezoid http://www.mathsisfun.com/geometry/trapezoid.html   a) Write a function that will return the area of a trapezoid b) Write a function that will return the perimeter of a trapezoid   2) Write a function int frequency (int theArray [ ], int n, int x) that counts the number of times the item x appears among the first n elements of theArray and returns that count as the frequency of x in theArray. Use integers for everything!  For example, if the array being passed contained the values 5, 7, 23, 8, 23, 67, 23 … and n was 7 and x was 23, then it would return a value of 3 since 23 occurs 3 times within the first 7 elements of the array.   3a) The mathematical operation max(x,y,w,z) can be represented by using the conditional expression operator, as in: max = (x > y && x > z && x > w) ? x : ((y > z && y > w) ? y : ((z > w) ? z : w)); Write a corresponding if else statement that is equivalent to the statement above that will set max to the largest value of x, y, w, or z. 3b) Conversely, use a conditional expression operator to rewrite the statement below:   if (x > 0) sign = 1; else if (x == 0) sign = 0; else sign = -1; 4. Given the following test scores and grade equivalents, write a function which is passed a score, and returns a letter grade based on the score entered. A number less than 0 or greater than 100 is invalid. Score Grade —— —– 90-100 A 80-89 B 70-79 C 60-69 D 0 -59 F   5) Write a function that is passed an array of characters containing letter grades from our previous question, and prints a report that shows the total number of occurrences of each letter grade. Your function should accept both lower and upper case grades, for example, both ‘b’ and ‘B’ should be bucketed into your running total for B grades. Any grade that is invalid should be bucketed as a grade of ‘I’ for Incomplete. You must use a switch statement, and your function should accept an array of any size. Feel free to pass in the array size as parameter so you know how many grades you’ll need to check in your loop. For example, if you passed the function the following array: char grades [ ] = {‘A’, ‘b’, ‘C’, ‘x’, ‘D’, ‘c’, ‘F’, ‘B’, ‘Y’, ‘B’, ‘B’, ‘A’}; It would print: Grade Total —– —– A 2 B 4 C 2 D 1 F 1 I 2 6) Write a program that contains a main function and three other functions that will return various attribute information about an array of floating point numbers: array_sum – total sum of all array elements array_avg – average of all array elements array_min – the smallest number of the array elements The main function should print the values returned from each function at the end of the program. 7. Write a function that raises an integer to a positive integer power. Call the function x_to_the_n, taking two integer arguments x and n. Have the function return a long int, which represents the results of calculating x to the nth power. Do not use the C pow library function. Example: if x = 3 and n = 2, the function would return 9.   NOTE: Do not use recursion (since that version is in your lecture notes). 8. The Federation has asked you to develop a program to keep track of its officers. A sample of the kind of information for each officer is shown below. Name: Mr. James Tiberius Kirk Date of Birth: March 22, 2233 Address: 23 Falling Rock, Riverside, Iowa 52327-0021 Planet Earth Rank: Captain Ship: USS Enterprise Nickname: Jim Favorite Saying: ‘Bones???’ Starting Stardate: 41153.7 Martial Status: Single Starfleet Graduation Date: June 23, 2212 Name: Mr. Leonard A. McCoy Jr. Date of Birth: 7/8/2227 Address: 8745 South Road Jackson, Mississippi 39201-0001 Planet Earth Rank: Chief Medical Officer Ship: USS Enterprise Nickname: Bones Favorite Saying: ‘He’s dead Jim.’ Starting Stardate: 41151.8 Marital Status: Divorced   Starfleet Graduation Date:  June 21, 2210 Provide the code need to DECLARE an array of structures given the above information. Don’t write a program and don’t worry about initializing the structure based on the information above. Be careful on how you declare the members of a structure. Grading will be based on how the flexibility of your design (i.e., define many structures and have structures within structures if necessary). Note: Don’t go overboard such as having a structure with only one member just to create many structures.
