Explanation

In the above program, we created a module Module1 that contains a Main() function.

The Main() function is the entry point for the program. Here, we created a decimal variable Num, which is initialized with the value "145.85" then we printed the variable in the invalid format then FormatException gets generated and caught in the catch block and prints the appropriate message on the console screen.
