In C++ Write the definition of a void function that has two parameters: an array, and an integer parameter that specifies the number of elements in the array.  The functions swaps the first and last elements of the array.

In C++ Sort an array from largest to smallest (you may use one of the sorts we did, you just have to change it so that it goes from largest to smallest instead).

Explain the use of the following notation in a C++ program:template< typename T > Array< T >::Array( int s )

3. How is an array initialized in C language? int a[3] = {1, 2, 3}; int a = {1, 2, 3}; int a = new int[3] int a(3) = [1, 2, 3];

Q/ Write a program in C# that lets the user to define the number of rows and columns. Then, the program reads the matrix and finds the index of the even and odd numbers and display them with their corresponding indices. Use adequate messages during the program execution.

write a program in C++ that allows the user to enter 10 songs and their artists into a playlist and will sort the entries by artist order.  The program should use a 10 element array of structure objects that holds two string variables:  artist and title.  Once the data has been read in and stored, it should sort the entries in ascending order by artist.  It should then display the sorted array with appropriate headings. Modularity:   The main function should create the Playlist object and call at least three other functions: Get the data from the user. Using a loop, have the user populate the playlist object array with 10 artist and songs in no particular order. No validation is necessary.   However, you should use the C++ getline function instead of cin so that the user can type spaces in the name and song title. Sort the list. You may use either the bubble sort or the selection sort to sort your playlist. Display the list. The function should display the artist and title in sorted…

What benefits do enumeration types provide over a collection of named constants? What benefits does a subrange type have over its base type? When might a string be preferable over a character array?

Instructions: In Basic C Language In the code editor, you are provided with a main function that asks the user for an integer input and passes this value to a function called, getFactorial() The getFactorial() function has the following description: Return type - int Name - getFactorial Parameters - one integer Description - returns the factorial of the passed integer Your implementation should be RECURSIVE and you should not use any loops Input #include<stdio.h> int getFactorial(int); int main(void) {    int n;    printf("Enter n: ");    scanf("%d", &n);     printf("Factorial of %d is %d", n, getFactorial(n));     return 0;} int getFactorial(int n) {    // TODO: Implement this recursive function}   Output should be: Enter n: 3 Factorial of 3 is 6

Array Challenge 3. Write a program in C# to find the sum of all elements of the array.Test Data :Input the number of elements to be stored in the array :3Input 3 elements in the array :element - 0 : 2element - 1 : 5element - 2 : 8Expected Output :Sum of all elements stored in the array is : 15
