Explanation
In the above program, we created a module Module1 that contains the Main() function. The Main() function is the entry point for the program. And, we created a local variable str of string type. After that read data from the "sample.txt" text file and print data on the console screen. If a specified file does not exist in the computer system then a file not found exception gets generated and prints an appropriate message on the console screen.
