Write a C# Sharp program to determine whether the string "birds" is a substring of a familiar string.

Note : Quotation ‘two birds with one stone'.

Sample Solution:-

C# Sharp Code:

using System;

class Example38
{
    public static void Main() 
    {
        string str1 = "Kill two birds with one stone"; // Original string
        string str2 = "birds"; // Substring to be checked

        // Check if str1 contains str2 using str1.Contains()
        bool x = str1.Contains(str2);
        Console.WriteLine("'{0}' is in the string '{1}': {2}",
                            str2, str1, x);

        // If str2 is found in str1
        if (x) {
            // Get the index of the first occurrence of str2 in str1 using str1.IndexOf()
            int index = str1.IndexOf(str2);

            // Display the index where str2 begins in str1
            if (index >= 0)
                Console.WriteLine("'{0}' begins at character position {1}",
                                    str2, index + 1); // Adding 1 to index to adjust to human-readable position
        }
    }
}

Sample Output:

'birds' is in the string 'Kill two birds with one stone': True                                                
'birds begins at character position 10

Previous: Write a C# Sharp program to concatenate the array values of strings.
Next: Write a C# Sharp program to creates two string objects with different values. When it calls the Copy method to assign the first value to the second string, the output indicates that the strings represent different object references although their values are now equal. On the other hand, when the first string is assigned to the second string, the two strings have identical values because they represent the same object reference.
