1 Converting First Character of "hello world" String to Uppercase

In this example,

  2. We convert the first character of str1 to uppercase using the ToUpper() method.
  3. Finally, we concatenate the modified first character with the rest of the string and print the result.

C# Program

using System;

class Program
{
    static void Main()
    {
        string str1 = "hello world";
        string modifiedStr1 = char.ToUpper(str1[0]) + str1.Substring(1);
        Console.WriteLine("Modified string is: " + modifiedStr1);
    }
}

    static void Main()
    {
        string str2 = "csharp";
        string modifiedStr2 = char.ToUpper(str2[0]) + str2.Substring(1);
