The sample input will have to be in Text File (.TXT) 2. By using the first function, this program reads score and name values from a file. The program then determines the grade for each students by using the second function. Finally, the program displays the name, score, and grade information on the console. The two functions are shown in the images attached below

Create a grading program in C as follows.- Ask the user for the number of students and store it in an integer variable.- Create an array of floats with four rows and columns equal to the number of students storedearlier.- Initialize the array to zeros.Create a menu with the following options (use a do-while loop and repeatedly display the menu):A or a to add student info one student at a timeT or t to display class average for homeworkS or s to display class average for quizzesB or b to display class average for examsZ or z to exit program (program repeats until this exit command is entered)The information for each student is: student number, homeworks grade, quizzes grade, and examsgrade.

The following functions are all supposed to count how many times a certain base (represented as a character variable in Python) appears in a dna sequence (represented as a string variable in Python): def count1(dna, base):     i = 0     for c in dna:         if c == base:         i += 1     return i   def count2(dna, base):     i = 0     for j in range(len(dna)):         if dna[j] == base:         i += 1     return i   def count3(dna, base):     match = [c == base for c in dna]     return sum(match)   def count4(dna, base):     return dna.count(base)   def count5(dna, base):     return len([i for i in range(len(dna)) if dna[i] == base])   def count6(dna,base):     return sum(c == base for c in dna) ======================================================================================= Which of them is correct? count 3, and count 6 only count 1, count 3, and count 4 only All of them are correct. count 1, count 3, count 4, and count 6 only

Validating User Input Summary In this lab, you will make additions to a Java program that is provided. The program is a guessing game. A random number between 1 and 10 is generated in the program. The user enters a number between 1 and 10, trying to guess the correct number. If the user guesses correctly, the program congratulates the user, and then the loop that controls guessing numbers exits; otherwise, the program asks the user if he or she wants to guess again. If the user enters a "Y", he or she can guess again. If the user enters "N", the loop exits. You can see that the "Y" or an "N" is the sentinel value that controls the loop. Note that the entire program has been written for you. You need to add code that validates correct input, which is "Y" or "N", when the user is asked if he or she wants to guess a number, and a number in the range of 1 through 10 when the user is asked to guess a number. Instructions Ensure the file named GuessNumber.java is open. Write loops…

Using a Sentinel Value to Control a while Loop in Java Summary In this lab, you write a while loop that uses a sentinel value to control a loop in a Java program that has been provided. You also write the statements that make up the body of the loop. The source code file already contains the necessary variable declarations and output statements. Each theater patron enters a value from 0 to 4 indicating the number of stars the patron awards to the Guide’s featured movie of the week. The program executes continuously until the theater manager enters a negative number to quit. At the end of the program, you should display the average star rating for the movie. Instructions Ensure the file named MovieGuide.java is open. Write the while loop using a sentinel value to control the loop, and write the statements that make up the body of the loop to calculate the average star rating. Execute the program by clicking Run. Input the following: 0, 3, 4, 4, 1, 1, 2, -1 Check that the…

Description Dot Product Task: Write a program that outputs the dot product of two given vectors. Your program should read the vectors from command line arguments, convert them to integers, output the vectors, and finally compute and output the resulting dot product. Let V and U be two vectors, where |V| we run the program as $ python dotproduct.py 156724 then the two vectors are V = [1, 5, 6] U = [7, 2, 4] and their dot product is calculated by V • U = (1 × 7) + (5 * 2) + (6 × 4) Example $ python dotproduct.py 1 23321 V = { 1, 2, 3 } U = {3, 2, 1 } V. U = 10 = ||U|= = 3 (the size of both vectors will always be 3). If
