Question
$marks = array(
"Sara" => array(
"
"
"Web" => 74,
),
"Diana" => array(
"Programming" => 78,
"DataBase" => 98,
"Web" => 66,
),
"Amy" => array(
"Programming" => 88,
"DataBase" => 76,
"Web" => 99,
),
);
1 : sort the array by the name of student from A-Z;
2 : search if Ram is exist :
if exiset print the value; else : student does not exist
3 : calculate the avg of each student and print it as :
the avg for Sara is : 84.66

- Code Should Be in Java: use loops, if statements, arrays, scanner etc Write an application that stores at least five different college courses (such as CIS101), the time it first meets in the week (such as Mon 9 am), and the instructor (such as Johnson) in a two-dimensional array. Allow the user to enter a course name and display the corresponding time and instructor. If the course exists twice, display details for both sessions. If the course does not exist, display an error message. Save the file as TimesAndInstructors.javaarrow_forwardInput Parameters: sea: an array of integers indices': an array of integers (each of which may or may not be a valid index for sea") Assumptions: sea may be empty. indices may be empty. *indices may contain duplicates. What to return? - For each integer value in 'indices', if it is a valid index for input array ssa', then use it to index into 'sea' and include the result in the output array. For example: Say ssa' is (23, 46, 69} and indices' is (2, -1, 0, 3, 0, 2} (where indices -1 and 3 are invalid, so only indices 2, 0, 0, 2 are used) Then the method should return (69, 23, 23, 69} Note: Order of elements in the output array corresponds to the order in which valid indices in the 'indices' array are arranged. That is, the output array may be empty if the input array sea is empty, or if the input array indices does not contain any valid indices. See the JUnit tests related to this method. */ public static int () task1(int ) seq, int () indices) { int (] result - null; return result;arrow_forwardProgramming language C++arrow_forward
- Lab 5 : Arrays Please the attachment which is been given to Develop a C code that asks for a class size (maximum can be 20). Then it asks the user to enter all the marks and saves them in an array. Then it generates a report about the class status that includes the following 1- Class average 2- Best mark and worst mark 3- number of failed students 4- Number of students with a grade of A and higher (80 or above) 5- number of students who got a mark above averagearrow_forwardC++ You have an array with non-repeating elements.

Error check and validate to ensure a legal integer was entered. If not, clear the cin buffer using clear() and ignore() and try again (Note: the buffer still needs to be cleared even if this step was successful).

- 1. Implement a class IntArr using dynamic memory. a. data members: capacity: maximum number of elements in the array size: current number of elements in the array array: a pointer to a dynamic array of integers b. constructors: default constructor: capacity and size are 0, array pointer is nullptr user constructor: create a dynamic array of the specified size c. overloaded operators: subscript operator: return an element or exits if illegal index d. "the big three": copy constructor: construct an IntArr object using deep copy assignment overload operator: deep copy from one object to another destructor: destroys an object without creating a memory leak e. grow function: "grow" the array to twice its capacity f. push_back function: add a new integer to the end of the array g. pop_back function: remove the last element in the array h. getSize function: return the current size of the array (not capacity) i.

RemoveBook(String name): to delete a book object from arraylist by a given name: Hint: you need to use iterator class and remove method. Book class: Fileds: bookld, bookname. Constructor: two parameterized constructor that accepts name a parameter Book(int ID, String name) ..... Methods: 1. Accessor method to return the name of the book 2. Mutator method to change the id of the book.
