"try" Code and "catch" Exceptions in the Frog program

because of the scope of the minutes variable, he moves the entire program into the Try-Catch expression.
Could't he just declare the variable at the beginning on the program?

My personal preference would be to have a limited try block ( and put the variable in the beginning of the program to have an overview )in order to not have to many things that can go bad in the try block. Also you can Int32.TryParse method to see if it is a number. -> https://msdn.microsoft.com/en-us/library/f02979c7(v=vs.110).aspx

That's also a valid approach. It only requires an extra line of code to declare the variable prior to the try. Then inside the try you can do a simple assignment.

His approach takes into consideration the fact that all of the moved code only makes sense when the Parse succeeds. Instead of thinking of it as being moved, consider it as being left as-is but with a try block wrapped around it.
