Indicate true or false for the following statements:
Every element in an array has the same type.
The array size is fixed after it is declared.
The array size declarator must be a constant expression.
The array elements are initialized when an array is declared.
True/FalseIndicate whether the statement is true or false.
1.
When you pass an array to a function, the computer passes the address of each of the array elements.
2.
When an array is sorted in descending order, the first element in the array contains the smallest value and the last element contains the largest value.
3.
The variables in an array are referred to as elements of the array.
4.
Assigning initial values to an array is not required, but considered good programming practice.
5.
Parallel arrays are two or more arrays whose elements are related by their position in the arrays.
6.
You should not pass a one-dimensional array to a function.
7.
Passing an array by reference is more efficient than passing it by value.
8.
The quick sort algorithm provides a quick and easy way to sort the items stored in an array, as long as the number of items is relatively small—for example, fewer than 50.
9.…
State whether the following are true or false. If false, explain why. a) Two pointers that point to different arrays cannot be compared meaningfully.

- Indicate true or false for the following statements: a. Every element in an array has the same type. b. The array size is fixed after an array reference variable is declared. c. The array size is fixed after it is created. d. The elements in an array must be of a primitive data typearrow_forwardC++ Programming. OVERVIEW OF DATA STRUCTURES. Task: Write a program to process a data array. Execute a custom task as a separate function or method of a custom class. When performing a task, use functional methods for manually entering array elements, generating random numbers, and printing array elements. Given an array of size N. Create a function to determine the element that is furthest from the arithmetic mean of the array elements (that is, the maximum absolute difference).arrow_forwardDefine the term " pointer print array " .arrow_forward
- NB: Square bracket notation for array access is NOT allowed for Question 3, i.e. array[i]. Array access MUST be facilitated by the use of pointers. Write a function, ReadFile(), that reads the content of the provided text file “Message.txt” and stores it in an array. The function receives as parameter a pointer to a character array where the content of the text file should be stored.. The number of lines that was read from the text file must be returned to the calling statement. Write a function, ReverseMyString(), that converts the character array (which now contains the contents of the text file) by replacing the first character with the last character, the second character replaced with the second last character, etc, until the message is reversed as shown in the Figure 3. The function receives as parameters, a pointer to the character array and an integer value indicating the length of the array. The function returns a 1 or 0 to indicate success and failure respectively. NB: You…arrow_forwardC++ Array Expander -Just do everything in main and make sure you comment each step Use Pointer Notation for the function and within the function. Use a main function and return the pointer from the ArrayExpander function to mainarrow_forwardTopic: pointers, dynamic array and command line arguments Write a function named "getDynamicNumList" that accepts a count (integer) for the totalof all the numbers to obtain storage for. The function will allocate an array of integer pointers dynamically, then read in from the user that many numbers. For each number, it will allocate memory for each integer initialized it with what the userenters and save its pointer in the new array. It then returns the pointer of the array of integer pointers to the caller. The caller should print out this array based on that description.Here is an example of calling getDynamicNumList with 4. It will allocate an array of 4 pointers and read in 10, 55, 76 and 1. Each integer will have its own dynamic memory location.arrow_forward
- Program in C language (Please solve part 2) Part one : Write a program that does the following: Creates int array array_1 of length 10. Creates int array array_2 of length 10. Takes int values from the user of for 10 values for array_1 and array_2, each. Creates a new int array array_3 which copies the values of array_1 and array_2, in interleaved order, into it. Prints out the contents of Prints out the contents of array_1, array_2 and array_3. Part two : Repeat Part one, but this time use arrays of char (instead of int), and stop receiving input into array_1 and array_2 when the user hits Enter / newline and insert a Null character into the arrayarrow_forwardQuestion 4: (30 marks) A Math teacher is teaching Math course to a set of classes (each class may have different number of students) and want to check the behavior of his students in a homework report. The teacher gave the classes the same exam and marked their answer and wants to know the class whose students got the highest average. Help the teacher in the required analysis of student’s marks by implementing a Java program ClassAverageMArks2DimmArray using 2-dimensional array to store the students marks and then compute the average of each class student’s marks. The program has the following specification: • A Method titled averageClassMarks for computing the average (as double) of a class students marks (given to the method as a single-dimensional array) • Another Method titled averageAllClassesMarks for computing the average (as single array of double) of all the classes class student’s marks (given to the method as a 2dimensional array). This method has to repeatedly call the…arrow_forward5. Identify the incorrect statement? Select one: a. Array size is static in a program once it has been declared b. None of the mentioned c. Value of an array element may be dynamically changed d. Array may have more than 2 dimensionsarrow_forward
- C Language: Answer the following 1. Write an appropriate array definition for each of the following problem situations:a. Define a one-dimensional, 12-element integer array called C. Assign the values 1, 4, 7, 10, …, 34 to the array elements.b. Define a one-dimensional character array called point. Assign the string “NORTH” to the array elements. End the string with the null character.c. Define a one-dimensional, four-character array called letters, assign the characters ‘N’, ‘S’, ‘E’, and ‘W’ to the array elements.arrow_forward3. Pointers – Arrays: initializing content • Using the pointer ptrArray, you now want to write values in those integers. Use a loop to go through each element in that array, and initialize them all to 42. This is done in the main. 4. Pointers – Arrays: printing • Write a function that will print the elements in the array-pointer. The function should accept a pointer to an integer, and the size of this array. The function should not return anything. Here is your function prototype: void printArray(int* ptr, int nb); • Your function needs to use a loop to go through all the elements in the array, and simply prints them on a new line. • In the main function, call this function with your pointer ptrArray and the size given by the user.arrow_forwardInstructions NOTE: For this practical you may not use the standard array notation to access elements within the array, such as array[i]. You must make use of pointers. Part 2 Write a C/C++ program that prompts the user to enter N integer values and stores it in an array. Display the array’s elements in reverse order.arrow_forward
