Proposed exercise
Create a program which asks the user for several numbers (until he enters "end" and displays their sum). When the execution is going to end, it must display all the numbers entered, and the sum again, as follows:
Enter a number: 5
Sum = 5
Enter a number: 3
Sum = 8
Enter a number: end
The numbers are: 5 3
The sum is: 8
Output
Solution
using System;
public class ManyNumbers
{
public static void Main()
{
float[] numbers = new float[1000];
float total = 0.0f;
int countArray = 0;
string entrada;
Console.Write("Enter a number: ");
entrada = Console.ReadLine();
