Can you help me write a C++ program to do the following: Create a function append(v, a, n) that adds to the end of vector v a copy of all the elements of array a. For example, if v contains 1, 2, 3, and a contains 4, 5, 6, then v will end up containing 1, 2, 3, 4, 5,6. The argument n is the size of the array. The argument v is a vector ofintegers and a is an array of integers. Write a test driver

9. Write function getMoveRow to do the following a. Return type integer b. Parameter list i. 1-d character array (i.e. move), size 3 c. Convert the row portion of the player’s move to the associated integer index for the board array d. Example: i. move = ‘b2’ ii. 2 is the row iii. 2 is index 1 in the board array e. Return the row array index that corresponds to the player’s move f. Return a -1 if the row is not valid (i.e. INVALID) 10. Write function getMoveCol to do the following a. Return type integer b. Parameter list i. 1-d character array (i.e. move), size 3 c. Convert the column portion of the player’s move to the associated integer index for the board array d. Example: i. move = ‘b2’ ii. b is the column iii. b is index 1 in the board array e. Return the column array index that corresponds to the player’s move f. Return a -1 if the column is not valid (i.e. INVALID)      I am getting an error when entering the code at the very end. please fix it.  This is the code in C     int…

a. Problem 1. Create an array of 30 random numbers that range between 1 and 100. Then, write a function that will receive a number from the user and determine if that number exists in the array or not. For instance, assume the array is: [2, 93, 14, 89, 12, 3, 81, 15, 14, 89, 52, 96, 71, 82, 5, 2, 41, 23, 52, 59, 44, 44, 88, 39, 49, 50, 97, 45, 48, 36] Now, assume the user enters 89, the program should output true. But, if the user enters 77, the program should output false. Approach: We will be implementing this method in two different ways. Both will be recursive. First, implement a method called findA (x,A), where x is the number we are looking for and A is an array. In the body of the function, compare x with the FIRST item that is in the array. If this first item is equal to X, return true. If not, remove the first item from A and call findA (x,A) on the revised list. If you call find on an empty list, you will want to return false. Writing any explicit loop in your code results a…

Hi, OCaml programming 1. Create a type slidingTile, consisting of a char matrix and two integers xand y. The integers x and y are the coordinates of an empty tile. 2. Create a function val slide : slidingTile -> int -> int -> slidingTile = <fun> that given a slidingTile and two integers, that represent a location in thematrix, it slides the tile from the specified location to the empty tile, thenreturns the altered slidingTile. If provided location is not adjacent to theempty tile, or out of bounds, then return the slidingTile unaltered. 3. Create a function val print_tile : slidingTile -> unit = <fun> that prints a slidingTile on screen with the corresponding characters fromthe matrix. However, print an empty space where the empty tile is instead.
