Functions in C#
Objective
1. Write a function named "IsAlphabetic" that takes a single character as a parameter.
2. The function should check if the character is between 'A' and 'Z' (inclusive) or 'a' and 'z' (inclusive).
3. If the character is alphabetic, return true; otherwise, return false.
4. Use the function in a sample program that checks whether a character is alphabetic or not and outputs an appropriate message.
Write a C# function that tells if a character is alphabetic (A through Z) or not. It should be used like this:
if (IsAlphabetic ("a"))
System.Console.WriteLine ("It is an alphabetic character");
(Note: do not worry about accents and ñ)
Example C# Exercise
Show C# Code
using System;
class Program
{
// Function to check if a character is alphabetic
public static bool IsAlphabetic(char c)
{
// Check if the character is in the range of 'A' to 'Z' or 'a' to 'z'
return (c >= 'A' && c <= 'Z') || (c >= 'a' && c <= 'z');
}
// Main method to test the IsAlphabetic function
public static void Main(string[] args)
{
// Test with a sample character
char testChar = 'a';
// Check if the character is alphabetic
if (IsAlphabetic(testChar))
{
// Output if the character is alphabetic
System.Console.WriteLine("It is an alphabetic character");
}
else
{
// Output if the character is not alphabetic
System.Console.WriteLine("It is not an alphabetic character");
}
}
}
Output
It is an alphabetic character
