write a program that finds a number of elements in an array without using built-in features

How does one go about keeping track of items that have data while working with an array that is only half populated?

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");

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9

What should a programmer be especially aware of when programming with arrays? Syntax errors If-then-else statements Modularization Using an Out of Bounds array subscript

JAVA PROGRAM: Monkey Business A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 ×ばつ 5 array, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey, or use constant values rather than asking user for input. Then it should create a report that includes the following information: Display 3X5 array first. Average amount of food eaten per day by the whole family of The least amount of food eaten during the week by any one The greatest amount of food eaten during the week by any one Input Validation: Do not accept negative numbers for pounds of food eaten.

The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below. The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. Processing Requirements - c++ Use the following template to start your project: #include<iostream> using namespace std; // Global constants const int ROWS = 3; // The number of rows in the array const int COLS = 3; // The number of columns in the array const int MIN = 1; // The value of the smallest number const int MAX = 9; // The value of the largest number //...
