Question

please use c++ language

1. Request three different integers from the console.

1. a) Write a swap function that swaps two integer values.

2. b) Write a sort function which accepts three integers as input then sorts

   them from largest to smallest using the swap function.

3. c) Output the integers before and after sorting.

Example 1 Output (input in bold italics)

Enter three different integers: 3 2 4

3 2 4
4 3 2

Example 2 Output (input in bold italics)

Enter three different integers: 15 23 63

15 23 63
63 23 15

Code a swap function not using c++ library function.

2. Implement an array of the English alphabet (26 characters).

a) Use a loop and casting to generate the array.
b) Output the array.
c) Create a swap function for swapping character variables.
d) Use a loop and the swap function to reverse all array elements. e) Output the updated array.

Hint: Set a variable for the first and last indices. Swap those values. Gradually move the first/last pointers to the middle of the array, swapping as you go. When the middle is reached, the array will be reversed.

Example Output (input in bold italics)
Original: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Reversed: Z Y X W V U T S R Q P O N M L K J I H G F E D C B A

please use c++ language using arrays only and a swap code function using upstream

3.

3. Randomly generate a partially filled array of unique values.

1. a) Create a blank partially filled integer array of capacity 10.

2. b) Implement an array output function.

3. c) Implement a hasElement function which accepts the array and an integer

   element as input. It checks the array for the element and returns true

   if the element exists, false if it does not.

4. d) Implement a randArray function which populates the array with random

   integers between 0 and 9 inclusive. This function should use the

   hasElement function to ensure all elements are unique (no duplicates).

5. e) Output the array. Confirm that all values (0-9) are included.

Example 1 Output (input in bold italics)

2 5 8 9 3 4 0 1 7 6
Example 2 Output (input in bold italics)

5 9 3 4 7 0 1 6 2 8

using iostream and srand time.h c++

Answer 1

1)

#include <iostream>
using namespace std;

void swap(int *a, int *b)
{
int temp = *a;
*a = *b;
*b = temp;
}

void sort(int *a, int *b, int *c)
{
if(a < b)
swap(a, b);
if(a < c)
swap(a, c);
}

int main() {
int a, b, c;
cout << "Enter three different integers: ";
cin >> a >> b >> c;
  
cout << a << " " << b << " " << c << endl; // printing before call
sort(&a, &b, &c);
cout << a << " " << b << " " << c << endl; // printing after call
  
}
