C# program to compare two user input characters:
This program will show you how to compare two user input characters in C#. It will take the characters as input from the user, compare them and print a message.
It checks if both characters are equal or not.
How to check if two characters are equal or not in C#:
In C#, we can check if two characters are equal or not in two different ways:
- Using ’==’
- Using ‘Char.Equals()’
Example program to compare two characters using == :
Using ==, we can simply compare two characters in C#. It returns true if both characters are equal. Else false.
using System;
public class Program
{
public static void Main()
{
char c1,c2;
Console.WriteLine("Enter the first character : ");
c1 = Console.ReadLine()[0];
Console.WriteLine("Enter the second character : ");
c2 = Console.ReadLine()[0];
if(c1 == c2)
Console.WriteLine("Both characters are equal");
else
Console.WriteLine("Characters are not equal");
}
}In this program, We are asking the user to enter the first and the second character. The characters are stored in c1 and c2 variables.
Using == operator, it checks if both characters are equal or not. Based on its result, it prints one message to the user.
It will give output as like below:
Enter the first character :
a
Enter the second character :
b
Characters are not equal
Enter the first character :
a
Enter the second character :
a
Both characters are equalExample program to compare two characters using Char.Equals:
Char.Equals is defined as below:
public bool Equals(char c)We can use this method with a character and pass another character to compare. Based on the boolean value it returns, we can say both characters are equal or not.
Let’s take a look at the below program:
using System;
public class Program
{
public static void Main()
{
char c1,c2;
Console.WriteLine("Enter the first character : ");
c1 = Console.ReadLine()[0];
Console.WriteLine("Enter the second character : ");
c2 = Console.ReadLine()[0];
if(c1.Equals(c2))
Console.WriteLine("Both characters are equal");
else
Console.WriteLine("Characters are not equal");
}
}It will give output similar to the above one.
