Q1.(a) Assume that each element of an array occupies four units of storage. If A is declared by each ofthe following and address of first element of A is 100. Find the address of indicated array elementif array elements are stored in row- major order and column major order:(i)int A [10][20] ; address of A[2][10] (ii) int A[10]20]; address of A[9][19]

Computer Science Q2) Write a Java program to retrieve all the index of a given element of the given array Input: 44, 6, 7, 100, 564, 3, 44, 2, 5, 44, 200 Element to be found: 44 Output: Element 44 is found at index 0, 6, 9
Write three functions for: mean, remove, display //include any standard libraries needed // - passes in an array along with the size of the array // - returns the mean of all values stored in the array double mean( const double array [ ], int arraySize); // - Passes in an array, the size of the array by reference, and the index of a value to be removed from the array. // - Removes the value at this index by shifting all of the values after this value up, keeping the same relative order of all values not removed. // - Refuces arraySize by 1. void remove (double array[], not &arraySize, int index); // - Passes in an array and the size of the array. // - outputs each value in the array separated by a comma and space, with mo comma, space or beeline at the end. void display (const double array[], int arraySize); const int ARR_CAP = 100; int main (int argc, char *argv[]){// verify file name provided on command line // open file and verify it opened // declare an array of doubles of…
ii) In JAVA language input the elements of an integer array A of size 10 and find the count of all hills in the array. A[i] is a Hill if A[i-1]A[i+1]. A[i] >= 0 All elements of the array are unique.
C program
d) Print all the elements of the array that are greater than the previous element at smaller than the next element. The first and the last element should be excluded. int arr[] = {5,14,66,7,22,39,0,-12,23,91}
Given the declaration: int matrix[7][5]; a) How many elements does matrix have? b) Write the statement to read an integer entered at the keyboard into the second row and second column of the array matrix. c) Assume that the array matrix has already been assigned values. Write a statement that outputs the number stored in the first column of the last row in the array matrix. d) Assume that the array matrix has already been assigned values. Write a for loop to calculate the total of the integers stored in the first row of matrix.
C++ Problem #1: Create a blank 10x10 integer array using constants for the row and column Create a function printArray() that will print every row and column of the array Create a function notFound() that searches each element in the array and returns true if the passed number already exists in the array and false if it does not Create a function fillArray() that will fill the 2 dimensional array with unique random numbers from 0 to 100 inclusive. No cells should have the same number. Use the notFound() function in this function. Print the entire array. Request a column number to print and use a sentinal loop to make sure the row number is valid. If not then request a column number again Create a function printIter() that prints only the passed column using iteration Create a function printRecur() that prints only the passed column using recursion Print the requested column using printIter() and printRecur() Sample output: The array is: Row 0: 41, 85, 72, 38, 80, 69, 65,…
Assume that the integer array myScores has been declared and assigned values. Assume that the integer variable size has been declared and initialized using the number of elements in the array myScores. Write a code block that declares a pointer to an integer and initializes it using the address of the array. Use that pointer to access the array elements, compute their average (as double), and display it on the screen.
