Proposed exercise
Create a function named "WriteTitle" to write a text centered on screen, uppercase, with extra spaces and with a line over it and another line under it:
WriteTitle("Welcome!");
would write on screen (centered on 80 columns):
---------------
W E L C O M E !
---------------
(Obviously, the number of hyphens should depend on the length of the text).
Output
Solution
using System;
public class FunctionWriteTiTle
{
public static void WriteTitle(string text)
{
int numOfSpaces =( 80 - text.Length * 2) / 2;
text = text.ToUpper();
int i = 0;
for(; i < numOfSpaces; i++)
Console.Write(" ");
for(i = 0; i < text.Length * 2 - 1; i++)
Console.Write("-");
Console.WriteLine();
for(i = 0; i < numOfSpaces; i++)
Console.Write(" ");
for(i = 0; i < text.Length; i++)
Console.Write(text[i] + " ");
Console.WriteLine();
for(i = 0; i < numOfSpaces; i++)
Console.Write(" ");
for(i = 0; i < text.Length * 2 - 1; i++)
Console.Write("-");
Console.WriteLine();
}
public static void Main()
{
WriteTitle("Welcome!");
}
}
