Write a C# Sharp program to perform an ordinal comparison of two strings that only differ in case..

Sample Solution:-

C# Sharp Code:

using System;

class Example31
{
    public static void Main()
    {
        // Declare two strings for comparison: "JAVA" and "python".
        String str1 = "JAVA";
        String str2 = "python";
        String str;
        int result;

        // Output the strings that will be compared.
        Console.WriteLine();
        Console.WriteLine("Compare the numeric values of the corresponding Char objects in each string.");
        Console.WriteLine("str1 = '{0}', str2 = '{1}'", str1, str2);

        // Perform an ordinal comparison using String.CompareOrdinal on the strings.
        result = String.CompareOrdinal(str1, str2);

        // Determine the relationship between the strings based on the result of the comparison.
        str = ((result < 0) ? "less than" : ((result > 0) ? "greater than" : "equal to"));

        // Output the result of the comparison between the strings.
        Console.Write("String '{0}' is ", str1);
        Console.Write("{0} ", str);
        Console.WriteLine("String '{0}'.", str2);
    }
}

Sample Output:

Compare the numeric values of the corresponding Char objects in each string.                                  
str1 = 'JAVA', str2 = 'python'                                                                                
String 'JAVA' is less than String 'python'.

Flowchart :

Go to:

PREV : Write a C# Sharp program to demonstrate that CompareOrdinal and Compare use different sort orders.
NEXT : Write a C# Sharp program to compare a given string with set of strings.
