- Exercise 2 This exercise is designed to assess student’s skills of writing programs using arrays and loops. Write a C++ program using array and loop that prompts a user to enter 15 Students’ marks in ProgramDesign and Implementation (PDI) Module in an array. The program sorts the students’ marks in descending order using a loop and displays the marks of all students as well as lowest, highest, average marks, and the class result based on the average module marks. The result criteria is given below:Average is less than 40 = Poor ResultAverage is between 40 to 49 = Fair ResultAverage is less than 50 to 59= Good ResultAverage is less than 60 to 69 = Very Good ResultAverage is between 70 to 79 = Excellent ResultAverage is 80 or greater = Outstanding ResultNote: You must demonstrate the use of arrays and loops. Your code must be properly commented Sample Output:Welcome to Result Management SystemEnter PDI Marks of Student 1: 50Enter PDI Marks of Student 2: 35Enter PDI Marks of Student 3:…arrow_forwardWhich aggregating operations are permitted for struct variables but not array variables, and which are prohibited for array variables?arrow_forwardC++ Do the following lab by an array(not vector) for 3 students find the average of a student by asking him how many grades do you have. The answer to this question, determine the size of the array(list of grades) and then ask the user to enter grades(the number of the grades is equal to the size of the array) then calculate the average for each student. Hence, you will calculate 3 averages. to calculate the average, use the array accumulator. Also when you get each grade validate it. validation for grade means that you check whether a grade is between 0 and 100. if the grade is negative or a grade is more than 100 then it is not valid and you have to ask the user to enter a grade again. Find the maximum and minimum grades for each student. Print the sorted list of the grades for each student. example: if grades user entered are: 60 78 98 23 45 then sorted list is:23 45 60 78 98arrow_forward
- Topic: Array covered in Chapter 7 Do not use any topic not covered in lecture. Write a C++ program to store and process an integer array. The program creates an array (numbers) of integers that can store up to 10 numbers. The program then asks the user to enter up to a maximum of 10 numbers, or enter 999 if there are less than 10 numbers. The program should store the numbers in the array. Then the program goes through the array to display all even (divisible by 2) numbers in the array that are entered by the user. Then the program goes through the array to display all odd (not divisible by 2) numbers in the array that are entered by the user. At the end, the program displays the total sum of all numbers that are entered by the user.arrow_forwardSummary In this lab, you use what you have learned about searching an array to find an exact match to complete a partially prewritten C++ program. The program uses an array that contains valid names for 10 cities in Michigan. You ask the user to enter a city name; your program then searches the array for that city name. If it is not found, the program should print a message that informs the user the city name is not found in the list of valid cities in Michigan. The file provided for this lab includes the input statements and the necessary variable declarations. You need to use a loop to examine all the items in the array and test for a match. You also need to set a flag if there is a match and then test the flag variable to determine if you should print the the Not a city in Michigan. message. Comments in the code tell you where to write your statements. You can use the previous Mail Order program as a guide. Instructions Ensure the provided code file named MichiganCities.cpp is…arrow_forwardWhen traversing an array, which of the following statements does not need to keep track of the individual array subscripts: Do...Loop, For...Next, or For Each...Next?arrow_forward
- Good evening, i am working on this arrays problem and was hoping you could help with it please? (my programming language is c++) Thanks!arrow_forwardDescribe how to pass an array as a parameter to a function.arrow_forwardC++ Write the program that outputs the following menu. The program should allow a user to input numbers into an array of integers. The array size should be 10. The first number should be stored in the zero position of the array. The next number should be stored in the next available location. Each option below should be written using a procedure, except Quit. Remember to comment the procedures with (given, task and return). (MENU) 1) Input number. 2) Sort numbers. 3) Output numbers 4) Quit Option 1) Allows the user to input a number and store it into the array. If the array is full no more numbers should be input. When the user select option 1 and the array is full it should output (Memory Full!). This option will only allow one number to be entered. If the user want to input another number they will need to select option 1 again. Option 2) This option should take the array and sort it in ascending order. Use the selection sort to do this. Option 3)…arrow_forward
- use c++ Programming language Write a program that creates a two dimensional array initialized with test data. Use any data type you wish . The program should have following functions: .getAverage: This function should accept a two dimensional array as its argument and return the average of each row (each student have their average) and each column (class test average) all the values in the array. .getRowTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row. .getColumnTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The function should return the total of the values in the specified column. .getHighestInRow: This function should accept a two…arrow_forwardTRUE OR FALSE, C++ When passing an array to a function, you must include & in front of the array name. When passing an array to a function, you must include & in front of the array name. It is possible to have a 2-dimensional array where each row has a different number of columns. The * is called the address of operator.arrow_forwardWhich aggregating operations are allowed for struct variables but not array variables, and which are not?arrow_forward
