Language: CReverse the elements of an array using pointers. To this end define the function void reverseArray (int* array , int arraySize). Inside the function, declare two int * pointers, one initially pointing to the first element in the array, the second one pointing to the last element in the array. Swap the values in the array indicated by each of these pointers. Increment the first pointer and decrement the second pointer. Repeat the process you reach the middle of the array. Print your original, and the reversed array.Problem 2. Problem 1:Write a funtion to swap the two float variables using pointers. Print the values before and after theswap. The function should take as arguments two float pointer type arguments. Initialize the floatvalues with the two float random numbers in the range (0, 10).Problem 2:Reverse the elements of an array using pointers.

Finish the swap function below using pointers and write the call to swap in the reverse function using the address of the array positions array[i] and array[size-i-1].using pointers. DON'T FORGET TO DECLARE THE PARAMETERS in the function. (Hint: if you can't figure it out with pointers, do it with the references #include <iostream>using namespace std; // Function to swap two ints using pointers// @param pointer to an int// @param pointer to an intvoid swap( ) {// TODO: Add code that swaps two integers using pointers } // Function to reverse arrayvoid reverse(int a[], int size) {for (int i = 0; i < size/2; i++) {// TODO: write the call to swap in the reverse function using the // address of the array positions array[i] and array[size-i-1].
1. Write a function called void swap with two parameters, which will receive the addressof x and y as pointer. The function should swap the value of x and y only if x is larger thany. Print the value of x and y after the function call. 2. Write a function called double getAverage(int *array, int SIZE), whereit accept the array as pointer, and return the average of the array. Print the returnedvalue from this function. Always use *array rather than subscript to access the arrayvalue.
2. Write a program which sorts the CGPA array having cgpa of all students in ascending order by using bubble sort and make use of pointers for each and every variable and constant and array.
Question 2In the following program, there is a call to the print_in_reverse function whichhas the following prototype: void print_in_reverse(float *a, int count); Using pointers, write this function to print the array in reverse order. #include <stdio.h>#define A_SIZE(A) sizeof(A)/sizeof(A[0]) void print_in_reverse(float a[], int count);int main(void) { float values[6] = { 12.1F, 22.2F, 32.3F, 42.4F, 52.5F, 62.6F }; printf("The array in reverse\n"); print_in_reverse(values, A_SIZE(values)); return 0;}
Write a function that accepts an int array and the array’s size as arguments. The function should create a new array that is twice the size of the argument array. The function should copy the contents of the argument array to the new array, and initialize the unused elements of the second array with 0. The function should return a pointer to the new array. Demonstrate the function by using it in a main program that reads an integer N (that is not more than 50) from standard input and then reads N integers from a file named data into an array. The program then passes the array to your array expander function, and displays the values of the new expanded array, one value per line. You may assume that the file data has at least N values. There are no prompts for the integer and no labels for the expanded reversed array that is printed out. If the integer read in from standard input exceeds 50 or is less than 0 the program terminates silently.
Given the code segment below, what should be the data type of a in the function prototype of func(), given the call from main()? Do NOT use array indexing notation. If it is an invalid access, write INVALID (in all capital letters) as your answer. void func( ______ a);int main(){ double aData[15];func(*aData + 15);return 0;}
Assuming an array declaration, int num[5], how will num be passed to a function?
6. Write a function that accepts an array of integers and returns -1 if sorted in ascending order, 1 if sorted in descending order, and 0 if not sorted. To be as efficient as possible, your function should make only one pass through the array.
5. Using c++, Write a function that determines the index of the second to the last occurrence of a target b in an integer array a. Return -1 if b is not in a or there is only 1 occurrence of b in a.

# Write a function to copy one array to another by using pointers. Comment/Discussion on the obtained results and discrepancies (if any).
C++ For this week’s assignment, you’ll be making a function that can multiply not only two matrices, but also a single matrix and a scalar. To build a matrix in C++, you’ll need to familiarize yourself with multi-dimensional arrays. These are the same as regular arrays, but when you initially define them, instead of saying:Int dataArray[10];You’d say:Int dataArray[10][10];This will create an array of 100 objects, that you can think of in a 10 x 10 grid. It should be noted that it’s actually the same as saying ‘int dataArray[100]’, and can be used in the same way.You can also initialize two-dimensional arrays like this:Int matrix[2][3] = {{ 0, 1, 2} ,{3, 4, 5}};Or like this:Int matrix[2][3] = {0,1,2,3,4,5};One of them’s just slightly easier to recognize as a two dimensional array than the other. Now while THIS project is only dealing with 2x2 matrices, it will be to your benefit if you plan your program to be able to handle matrices of any size...Your function will need to correctly…
