- Write answer in c++arrow_forwardSize of the array need not be specified, when A. Initialization is a part of definition B. It is a declaratrion C. It is a formal parameter D. All of thesearrow_forwardJAVAWrite a program that searches person's name and display all matched name. For example, if a user inputs the letter "Davis", the program searches all name which includes "Davis" in an array. Then, display all matched names on the screen. You must declare a single dimensional array which has all people’s name. Use methods of string classarrow_forward
- an int variable k, an int array currentMembers that has been declared and initialized, an int variable nMembers that contains the number of elements in the array, an int variable memberID that has been initialized, and a bool variable isAMember, Write code that assigns true to isAMember if the value of memberID can be found in currentMembers, and that assigns false to isAMemberotherwise. Use only k, currentMembers, nMembers, and isAMember.arrow_forward4. Remove all occurrences of a particular element from an array Consider an array named source. Write a method/function named removeAll( source, size, element) that removes all the occurrences of the given element in the source array. You must execute the method by passing an array, its size and the element to be removed. After calling the method, print the array to show whether all the occurrences of the element have been removed properly. nmm" Use Python Example: source=[10,2,30,2,50,2,2,60,0,0] removeAll(source,8,2) After calling removeAll(source,8,2), all the occurrences of 2 must be removed. Printing the array afterwards should give the output as: [ 10,30,50,60,0,0,0,0,0,0]arrow_forwardWrite a function in C language that will take a 2D Array of size 3x3 from the user. Your Program should: 1. Prompt the user to enter 2D array of size 3x3. 2. Calculate the sum of all rows. 3. Calculate the sum of all columns 4. Return 1 if the sum of all rows is greater than sum of all columns, 0 otherwise. Your main program should print the result based on the returned values.arrow_forward
- Debugging challenge: Consider the code example below. This program is designed to compare the contents of two arrays: if they are equal, the program should display "TRUE," if the arrays are not equal, the program should display "FALSE". However, even when the arrays have the same value, the program always prints "FALSE", regardless of the values in arrays a and b. What is going on here? What about the program causes the comparison to always fail? int a[4] {1, 2, 3, 4}; int b[4] = {1, 2, 3, 4}; if (a == b) { display ("TRUE"); else { display ("FALSE");arrow_forwardC#arrow_forwardPlease complete this program in C++ Please enusre that there is plenty of comments. PLENTY even if unessessary. Please include screenshots of actual code, screenshots of output, and code in the browser so I can copy and paste. Thank you.arrow_forward
- mergeAndRemove(int[], int[]) This is a public static function that takes a int[] and int[] for the parameters and returns an int[]. Given two arrays of integers. Your job is to combine them into a single array and remove any duplicates, finally return the merged array.arrow_forwardPlease use easy logic with proper indentations and comments for understanding!. Coding should be in C++. 3. Define a class which stores up to 10 integer values in an array. The class should also define the following 4 public methods: setNumber – accepts an integer value to store in the array. The value is stored in the next available element of the array (first call to the method stores the value in element 0 with the second call storing the value in element 1.) The method returns true if there is room in the array and the integer was successfully stored. Returns false otherwise. clear – removes all values from the array so that the array can be reused. displayNumbers – displays the values currently stored in the array. getStats – determines the largest, smallest, and average of the values currently stored in the array. These values are returned to the caller via reference parameters. All methods should produce correct results regardless of the order in which…arrow_forwardCODE IN JAVA design a program that grades arithmetic quizzes as follows: (Use the below startup code for Quizzes.java and provide code as indicated by the comments) 1. Ask the user how many questions are in the quiz. 2. Use a for loop to load the array. Ask the user to enter the key (that is, the correct answers). There should be one answer for each question in the quiz, and each answer should be an integer. They can be entered on a single line, e.g., 34, 7, 13, 100, 8 might be the key for a 5-question quiz. You will need to store the key in an array called "key". 3. Ask the user to enter the student's answers for the quiz to be graded. There needs to be one answer for each question. Note that each answer can simply be compared to the key as it is entered. If the answer is correct, add 1 to a correct answer counter. need this in a separate for loop from the loop used to load the array. 4. When the user has entered all of the answers to be graded, print the number correct…arrow_forward
