Oi,

Sou novo no C#. Estava treinando laços e tenho um problema a resolver: Preciso, com um laço for criar um programa no console que leia cinco números, some os cinco e imprima o resultado na tela. Alguem por favor pode ajudar!

[MACUL]

For Loop Syntax
Example 1

Suppose you want to reverse the {Customer.Customer Name} string. For example, "City Cyclists" becomes "stsilcyC ytiC".

//Reverse a string version 1
Local StringVar str := "";
Local NumberVar strLen := 
   Length ({Customer.Customer Name});
Local NumberVar i;
For i := 1 To strLen Do
(
   Local NumberVar charPos := strLen - i + 1;
   str := str + {Customer.Customer Name}[charPos]
);

Example 2

//Reverse a string version 2
Local StringVar str := "";
Local NumberVar strLen := 
   Length ({Customer.Customer Name});
Local NumberVar i;
For i := strLen To 1 Step -1 Do
(
   str := str + {Customer.Customer Name}[i]
);
str

Example 3

Para registro fica aqui a função nativa
The simplest version is to use the built in function StrReverse:

//Reverse a string version 3
StrReverse ({Customer.Customer Name})

QUANTO AO CONSOLE...

Console.Out.NewLine = "\r\n\r\n";.

Exemplo :

// System.Console.WriteLine

using System;
public class TipCalculator {
	private const double tipRate = 0.18;
	public static int Main(string[] args) {
		double billTotal;
		if (args.Length == 0) {
			Console.WriteLine("usage: TIPCALC total");
			return 1;
		}
		else {
			try {
				billTotal = Double.Parse(args[0]);
			}
			catch(FormatException) {
				Console.WriteLine("usage: TIPCALC total");
				return 1;
			}
			double tip = billTotal * tipRate;
			Console.WriteLine();
			Console.WriteLine("Bill total:\t{0,8:c}", billTotal);
			Console.WriteLine("Tip total/rate:\t{0,8:c} ({1:p1})", tip, tipRate);
			Console.WriteLine(("").PadRight(24, '-'));
			Console.WriteLine("Grand total:\t{0,8:c}", billTotal + tip);
			return 0;
		}
	}
}

/*
Example Output:
---------------

Bill total:	   $52.23
Tip total/rate:	$9.40 (18.0 %)
------------------------
Grand total:	  $61.63
*/

Thanks for the help.
I´ll try to adapt the code.
