- 4. b. If A is an array of integers with width = 4; Please translate withthree-address statement, the following expression: x = a[i] + 2;Mark the following statements as true or false. A double type is an example of a simple data type. (1) A one-dimensional array is an example of a structured data type. (1) The size of an array is determined at compile time. (1,6) Given the declaration: int list[10]; the statement: list[5] - list[3] * list[2]; updates the content of the fifth component of the array list. (2) If an array index goes out of bounds, the program always terminates in an error. (3) The only aggregate operations allowable on int arrays are the increment and decrement operations. (5) Arrays can be passed as parameters to a function either by value or by reference. (6) A function can return a value of type array. (6) In C++, some aggregate operations are allowed for strings. (11,12,13) The declaration: char name [16] = "John K. Miller"; declares name to be an array of 15 characters because the string "John K. Miller" has only 14 characters. (11) The declaration: char str = "Sunny Day"; declares str to be a string of an unspecified length. (11) As parameters, two-dimensional arrays are passed either by value or by reference. (15,16)Write C++ statements to define and initialize the following arrays. a. Array heights of 10 components of type double. Initialize this array to the following values: 5.2, 6.3, 5.8, 4.9, 5.2, 5.7, 6.7, 7.1, 5.10, 6.0.b. Array weights of 7 components of type int. Initialize this array to the following values: 120, 125, 137, 140, 150, 180, 210.c. Array specialSymbols of type char. Initialize this array to the following values: '$', '#', '%', '@', '&', '!', '^'.d. Array seasons of 4 components of type string. Initialize this array to the following values: "fall", "winter", "spring", "summer".
- 3. Consider an 1-d array of type int and a pointer pointing variable pointing to the 2nd item of the array. Write down the code for the following: int arr(10) = (5,6,23,4,89,70,12,78,33); int *ptr = arr+1; (a) Print the first item of the array using ptr. (b) Print all prime numbers of the array using value at address. (c) Print the last item of the array using a pointer to an array. You are not allowed to initialize the pointer to the address of the last item. Iterate using a loop to change the value of the pointer. (d) Now print the array in reverse order using a pointer. 101Using C/C++ . Assume that the following lists of numbers represents the physical view of a two dimensional array in memory. If the array has 3 columns and 3 rows, show the row majorordering and the column major ordering for each list.a) 4, 0, 1, 3, 5, 1, 7, 4, 4b) 7, 7, 7, 3, 3, 3, 1, 1, 1c) 1, 2, 3, 4, 5, 6, 7, 8, 9iv) Write a JAVA program to merge two sorted arrays into a single sorted array. Take the sample arrays given below and print the result in the output. The time complexity of the program should be O(N+M) where N and M are the sizes of both the arrays. int []arr1 = {1, 6, 10, 14} int []arr2 = {2, 4, 5, 11, 16, 19} Print the merged array in the output.
- 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…1-Write a C++ program to input elements in array and sort array elements in descending order. How to sort array in descending order in using pointers.Use function to print out the original and sorted arrays, Example Input Input size of array: 10 Input array elements: 20, 2, 10, 6, 52, 31, 0, 45, 79, 40 Output Array sorted in descending order: 79 ,52,45,40,31,20,10,6,2,039) Define a two-dimensional array named matrix of 4 rows and 3 col-umns of type double such that the first row is initialized to 2.5, 3.2, 6.0; the second row is initialized to 5.5, 7.5, 12.6; the third row is initialized to 11.25, 16.85, 13.45; and the fourth row is initialized to 8.75, 35.65, 19.45. 40) Suppose that array matrix is as defined in Exercise 39. Write C++ statements to accomplish the following: a.Input numbers in the first row of matrix. b.Output the contents of the last column of matrix. c.Output the contents of the first row and last column element of matrix. d.Add 13.6 to the last row and last column element of matrix.

Write the C11 statement that dynamically creates an array of 50 components of type double and assigns the base address of the array to sales.b. Write a C11 code that inputs data into the array sales from the standard input device.c. Write a C11 code that finds the index of the largest entry in the array sales.d. Write a C11 statement that deallocates the memory space of array to which sales points.C++ Implement Exercise 8-13 using single-dimensional parallel arrays. (8-13: Write a program to calculate students’ average test scores and their grades. Your program must contain at least the following functions: a function to read and store data into two arrays, a function to calculate the average test score and grade, and a function to output the results.
