C# Arrays, Structures and Strings
Objective
1. Ask the user to input a string.
2. Calculate the total length of the string.
3. Display each line of the string, starting with just the first character on the first line and gradually adding one character at a time until the entire string is displayed.
4. Ensure that the characters on each line are centered horizontally.
5. For the centering, you can pad the output with spaces to ensure the triangle aligns correctly.
Write a C# program that Display a centered triangle from a string entered by the user:
Enter your string: Juan
__a__
_uan_
Juan
Example C# Exercise
Show C# Code
using System;
class Program
{
static void Main()
{
// Ask the user for their string input
Console.Write("Enter your string: ");
string input = Console.ReadLine();
// Calculate the total length of the string
int length = input.Length;
// Loop through the string, creating each line of the triangle
for (int i = 1; i <= length; i++)
{
// Get the substring of the first 'i' characters
string substring = input.Substring(0, i);
// Calculate how many spaces are needed for centering
int spaces = (length - i) / 2;
// Display the substring with the appropriate spaces for centering
Console.WriteLine(new string(' ', spaces) + substring + new string(' ', spaces));
}
}
}
Output
Enter your string: Juan
__a__
_uan_
Juan
