For the array ADT, the operations associated with the type array are: insert a value in the array, delete a value from the array, and test whether a value is in the array or not. 1.true 2.false
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");
12. Index Specialist by Jundith Alterado So, I have this job which is to look for a value inside an array and record all the index/indices that contains it. But... I'm just to lazy to do it manually. Can you help me create a program that would ask the user for the size and elements of an array as well as the value of the element that need to be searched. It will traverse the array and look for the index/indices where that value is found. If the element is not found in the array you will instead state "Element [value] is not found in the array." In this way, I can sleep a little bit longer during worktime. I know I can count on you! Input 1. The size of the array Constraints The value is within the range: 0 = 0 3. Value of the element to be searched Output The first line will contain a message prompt to input the size. The succeeding lines will contain a message prompt to input the elements of the array. The first line will contain a message prompt to input the value of the element to…
JAVA CODE PLEASE Functions with 2D Arrays Practice I by CodeChum Admin Write a function named displayElements that takes a two-dimensional array, the size of its rows and columns, then prints every element of a two-dimensional array. Separate every row by a new line and every column by a space. In the main function, call the displayElements function and pass in the required parameters. An initial code is provided for you. Just fill in the blanks. Output 1·2·3 4·5·6 7·8·9

Problem2 Write a program that display the position of a given element in an array. You should print the index (i.e. the position) of the element. If the element appears more than one time than you should print all its positions. The size of the array should be entered by the user. If the element does not occur then you should display element not found. Sample1: Enter the size of the array: 5 Enter an array of size 5: 44 5 13 44 67 Enter the element to find: 44 44 is found at position 44 is found at position 44 occurs 2 time(s) Sample2: Enter the size of the array: 4 Enter an array of size 4: 12 150 17 20 Enter the element: 18 18 is not found
Probably 7.
1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.
. Create an integer type array whose size to be entered by the user using calloc function. After entering the data elements, modify its size using realloc function and then entered the remaining elements in the array. Find the total number of even and odd elements in the final array.
Write pseudo code for given statemente. The amount variable is set to 0, and then each is called on the array. Each of the values in the array is passed to the block. Each time the block is called, amount is updated:
Q2: Write a C# program that read an array A(4x4) of float numbers, and do the following: 1- Print the average of prime numbers in the overall array. 2- Print the summation of odd numbers in the even column and even numbers in the odd row. 3- Replace the first row with the last row and print the new array row by row. Don't use class or functions.
