Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Write a program that stores this information in a two-dimensional 3×7 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. Then it should create a report that includes the following information: Average amount of food eaten per day by the whole family of monkeys The least amount of food eaten during the week by any one monkey The greatest amount of food eaten during the week by any one monkey.

Multi Dimensional Arrays in C Program Ask the user for the number of rows and columns of a two-dimensional array and then its integer elements. Then, ask the user for another integer value which represents a boogeyman. A boogeyman is a value that we intend to find from a given array. Find and output the coordinates of the boogeyman by this format: "BOOGEYMAN LOCATED AT ROW {row_number}, COLUMN {column_number}!" Input 1. One line containing an integer for the number of rows 2. One line containing an integer for the number of columns 3. Multiple lines containing at least one integer each line for the elements of the array Sample 1 4 2 3 9 1 2 3 4 2 1 1 9 2 8 3 4.

Programing C Just with #include Matrix Addition and Subtraction (Associatively) Write a program that performs matrices addition and subtraction. As shown in the example below, you have to ask the user for the number of rows and number of columns that both matrices should have (they both have to be the same size, that is why you only ask once). You will then ask the user for the values of each matrix. Then, you will print the values that the user inputted, the added values of both matrices, and the subtracted values (matrix 2 should be subtracted from matrix 1). In this challenge Guidelines/steps: • The number of rows and the number of columns should be global variables. • Once you get these two from the user, you should declare your two matrices in main. • Then, from main, you will call function aaa twice; first, you will send matrix 1 and populate it with values inputted by the user. You will call the function a second time, send matrix 2 and populate it. In other words, function aaa…
