Explanation:

Here, we created a class TrimDemo that contains the Main() method. The Main() method is the entry point of the program. Here we declared a string variable str, and then read the value of the string. After that, we printed the string before calling TrimEnd() and method and then trimmed the string from the right side using the TrimEnd() method and printed the trimmed string on the console screen.
