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.

Question

1) Given row array vals of unknown size of 2 or greater, write an
expression that yields a new array containing all elements except the
first. For example, if vals = [10, 20, 30, 40], the expression
would yield [20, 30, 40].

2) Write an expression that results in a row array vals shifted to the
right. For example, if vals = [1, 2, 3, ....., n-1, n], then a right
shift will result in [n,1,2,3,.....n-1].

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
Programming in C language. RandomNumbers Declare an integer array locally with the size of 200. Create a program that asks the user how many numbers the have. Use your getChoicel) function from before. Make sure it does not exceed 200 as the locally declared array has the size of 200. Use a loop to assign random numbers from 1 to 10000 to the array elements. (Remember to use srand() to seed the random number generator). Use a second loop to display each number, and also determine the average of all values in the array. You must also find the largest and the smallest numbers. After the for loop, display the average of all numbers. This program will let you enter a list of numbers into an array. It will then display all of the numbers, and finally display the average of all numbers. How many numbers would you like to enter?10 Number 1 is 42 Number 2 is 8468 Number 3 is 6335 Number 4 is 6501 umber 5 is 9170 Number 6 is 5725 Number 7 is 1479 Number 8 is 9359 Number 9 is 6963 Number 10 is…
Task using C language Write a program that checks both of the following conditions hold for a given array a1, a2, …, an. If the conditions hold, display “yes”, otherwise, display “no”. a1 < a2 < … < an For every i from 2 to n, ai isn’t divisible by ai-1. Requirements Follow the format of the examples below. The program reads in the number of elements of the array, for example, 4, then read in the numbers in the array, for example, 3 6 8 9. In the main function, declare the input array after reading in the number of elements of the array, then read in the elements. Examples (your program must follow this format precisely) Example #1 Enter the length of the input array: 7Enter the array elements: 2 5 4 1 6 9 12Output: no Example #2 Enter the length of the input array: 6Enter the array elements: 2 7 13 19 23 43Output: yes
Language: C Pascal’s triangle is a triangular array, useful for calculating the binomial coefficients, n k , that are used in expanding binomials raised to powers, combinatorics and probability theory. 0 0 1 0 1 1 2 0 2 1 2 2 3 0 3 1 3 2 3 3 4 0 4 1 4 2 4 3 4 4 Evaluating the values of the binomial coefficients, you get the following pattern, 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 The number of the entries in each row is increased by one, as we move down. Each number in the triangle, is constructed by adding the number above it and to the left, with the number above it and to the right. The blank entries as treated as 0. Using the recursion, implement the function that computes the Pascal’s triangle. Pr
The following program is supposed to let the end-user enters 10 numbers in a one dimensional array. The program must then check the input numbers in the following order and way: 1f the input number is a negative one, the program should multiply that number by (5), and return the number of negative elements in the array. 2. if the input number is a positive one, the program should multiply that number by (2), and return the number of positive elements in the array. 3. if the input number is a zero, the program should return the number of zeros in the array The program code is given below with some missing code. You are required to write the missing code ONLY in order to make the program complete. Sample Input/Output Enter 10 numbers in the array -8 -16 16 80 2 12 -12 -2 0 -40 -80 32 16 0 4 24 -60 -10 0 The number of negative elements is: 4 The number of positive elements is: 4 The number of zeros is: 2 dinclude using namespace std; int main() int input[10], i, negative-0, positive-0,…
initialise a variable named Min and set its value equal to first item of array. start a for loop to iterate through every element of marks array. check if item<Min. if 4 is true: set Min = item, else continue after the loop will finish, Min variable will have lowest marks For total marks for all the students. initialise a variable named Sum and set its value equal to zero. start a for loop to iterate through every element of marks array. for every iteration, do sum = sum+item after the loop will finish, sum variable will have total marks of all students The overall average. initialise a variable named Sum and set its value equal to zero. initialise another variable count =0. start a for loop to iterate through every element of marks array. for every iteration, do sum = sum+item, and increase count by 1. after the loop will finish, sum variable will have total marks of all students and count will have total count of marks. 5. to calculate average, do average = sum/count.
Q2: Write a C# program that generates an array Y(3x3) randomly (between 55, 666) and print: The average of prime number in secondary diagonal. The summation of each row. The number of odd elements of each even column. Note: Don't use classes or functions to solvethe question
Question 3: An array listA is called balanced if it stores the same count of even and odd integers. Write a program to test an array listA filled with 10 integers {22,5,18,4, 9,12,13,17, 23,24}. Then the program will output the integers stored in listA and from initializer list an as follow: checks if the array listA is balanced or not. Sample Run: listA store: (22 5 18 4 9 12 13 17 23 24} listA is a balanced array am
In statistics the mode of a set of values is the value that occurs most often. Write a program that determines how many pieces of pie most people eat in a year. Set up an integer array that can hold responses from 30 people. For each person, enter the number of pieces they say they eat in a year. Then write a function that ﬁnds the mode of these 30 values. This will be the number of pie slices eaten by the most people. The function that ﬁnds and returns the mode should accept two arguments, an array of integers, and a value indicating how many elements are in the array.
Assignment Write a program that reads a 2D array of chars, checks, and corrects each char within this array, and print out the corrected 2D array. First the program will read the row count (rowCount) and column count (columnCount) of the 2D array, both as int values. Then, the chars constituting the 2D array will be read on a row-by-row basis. After reading the 2D array, the program will check and correct each char within the 2D array according to the rules below. This process MUST be done by using a void function by sending the appropriate cell of the 2D array with a call-by-reference fashion. • If the row index is an even number, a char can only be a lowercase English value. • If the row index is an odd number, a char can only be ?, 7', or X'. • Any incorrect value MUST be changed into Finally, the checked and corrected 2D array will be printed out to the screen. NOTE: Checking the correctness of a char and correcting it (if necessary) MUST be done in the function with a…
Input: The first line will consists of one integer T denoting the number of test cases. For each test case: 1) The first line consists of two integers N and K, N being the number of elements in the array and K denotes the number of steps of rotation. 2) The next line consists of N space separated integers, denoting the elements of the array A. Output: Print the required array. Constraints:
8. A magic square is an n by n square in which each element is an integer between 1 and n*n and all column sums, row sums and diagonal sums are equal. For example, the following is a 3 by 3 magic square in which each row, each column, and each diagonal adds up to 15. 4 3 8 9 1 7 6. Write a program that accepts a two-dimensional array size 10 by 10. The program should check and output whether it is a magic square or not. What is the output of the following code?
