Answer to Question #331649 in C++ for Zaki

Question

Write a C++ program that creates an array “A” having 5 elements (in the main function). Then,

the program asks the user to enter values in this array. After that, the program should ask

question from user are you wanted to sort ascending or descending order kindly enter your

choice that’s you want to search in the array, also compute the sum of array for the ascending

order and difference of array for the descending order.

Answer 1

#include <iostream>
#include <algorithm>


using namespace std;


void Menu()
{
	cout << "Please, choose some of the following:"
		<< "\nA - Sort in ascending order"
		<< "\nD - Sort in descending order";
	cout << "\nYour choice: ";
}


bool Descending(int a, int b)
{
	if (a > b)
		return true;
	else
		return false;
}


int main()
{
	const int N = 5;
	int A[N];
	cout << "Please, enter 5 values of an array: ";
	for (int i = 0; i < N; i++)
	{
		cin >> A[i];
	}
	cin.ignore(256, '\n');
	char choice;
	Menu();
	cin >> choice;
	switch (choice)
	{
		case 'A':case 'a':
		{
			sort(&A[0], &A[N]);
			double sum = 0;
			for (int i = 0; i < N; i++)
			{
				sum+= A[i];
				cout<<A[i]<<" ";
			}
			cout << "\nThe sum of an array is " << sum;
			break;
		}
		case 'D':case 'd':
		{
			sort(&A[0], &A[N],Descending);
			double dif = A[0];
			for (int i = 0; i < N; i++)
			{
				if(i!=0)
					dif -= A[i];
				cout << A[i]<<" ";
			}
			cout << "\nThe differnce of an array is " << dif;
			break;
		}
	}
}
