- Parallel Array in Java Summary In this lab, you use what you have learned about parallel arrays to complete a partially completed Java program. The program should either print the name and price for a coffee add-in from the Jumpin’ Jive coffee shop or it should print the message: "Sorry, we do not carry that.". Read the problem description carefully before you begin. The data file provided for this lab includes the necessary variable declarations and input statements. You need to write the part of the program that searches for the name of the coffee add-in(s) and either prints the name and price of the add-in or prints the error message if the add-in is not found. Instructions Study the prewritten code to make sure you understand it. Write the code that searches the array for the name of the add-in ordered by the customer. Write the code that prints the name and price of the add-in or the error message, and also write the code that prints the total order cost. Execute the program…//////////// //////////// //////////// how do i solve this problem in java. please do not use arraysExercise #1: Write a C program that contains the following steps. Read carefully each step as they are not only programming steps but also learning topics that explain how numeric arrays in C work. Write a while loop to input a series of numbers (either from a file or from the keyboard, but using a file will make for easier debugging) into a one dimensional array of type double named x_arr, declared to be 25 elements in length. Count the elements as you input them. Then in a second loop, a for loop this time, print out all the elements which were input. Make up your own data file for this problem. Extend your code by writing a for loop to find the largest value in the array. The largest value should go into a variable named xhigh. Your code should then print out xhigh. Extend your code by writing a for loop to find the smallest value in the array. The smallest value should go into a variable named xlow. Your code should then print out xlow. Extend your code to produce a second array…
- Q6: Write a complete program in C++ that declares a one-dimensional array of integers. First, you have to read and print the array elements then you have to find and print the number of positive numbers and the number of negative numbers. (10 Marks)Question 2: Student Grades Report Java ProgramIn this question, write a complete Java program to prompt the student for a sequence of courseswith its grade in the format of “Course1|Grade1;Course2|Grade2;Course3|Grade3;” as one string. Yourprogram should separate the string into the course name and grade individually and save the coursenames and grades in two different arrays (2D-character array for course names and integer array forgrade) and display the list of courses, average of the grades as a numerical value and letter accordingly.You can expect a perfect user who will enter the correct format. Your program should work for anynumbers of course that were entered. Note: The table below depicts the numerical grades and their corresponding letter grade. Letter Grade Numerical Value A ≥88 B ≥ 80 C ≥ 67 D ≥ 60 F < 60What are the pros and downsides of Array?
- c++ What will be the values in the array after the following lines of code executes. int numbers[5]; int *p; p = numbers; *(p + 2) = 150; p = &numbers[3]; *p = 12; p++; *p = 11; p = numbers + 2; *p = 103; p = numbers; *p = 107; numbers[1] = *p + numbers[1];Do the following in the most efficient way possible in C Language: 1. Take an Array of 10 integer values (automatically should be converted to ascending order). 2. Insert Values - Value should be inserted automatically as per the ascending order. If array is {1,7,28,45,67,81} and the user inserts 31; the program should automatically insert at the 3rd index and array size should increase by 1. 3. Delete Values by Range - the user will be asked to two indexes (<sizeofArray) and all values in between those indexed should be deleted. E.g. If array is {1, 7, 28, 45, 67,81} and user enters the indexes 2,4. Then the values 28, 45, 67 should be deleted.Do the following in the most efficient way possible in C Language: 1.

Please do not use Pointers and only use Array as a Data Structure.
- CODE USING C++ 1. Please Fix Me by CodeChum Admin Hi dear Programmer, I am broken. Can you please help me fix me? ?? Instructions: In the code editor, you are provided with a main() function that declares an array, sets its values, and then prints the sum of all of its values. However, there is a problem with how the array is declared. The array should be able to store 5 values. Your task is to fix the me array's declaration. Output 25Given the following struct definition; #define MAX 20 typedef struct{ int items[MAX]; int count;}Array;Define the functions:void addItem(Array *a, int item); // adds item to the arrayvoid printArray(Array a); // displays elements of itemsint isFull(Array a); //returns 1 if the items is full; 0 if otherwiseint isEmpty(Array a); //returns 1 if the items is empty; 0 if otherwiseExplain following code segment:int [] a = new int [3];int [] b = new int [3];a = b;
