C# C# Basics Numbers Converting Strings to Numbers

Could you parse the return value from Ask instead of making a new variable?

Instead of making a the new variable number to do the math with, couldn't you just parse the value returned by the Ask method?

For example:

  int entry = int.Parse(Ask("How many cans are you ordering?"));
  Console.WriteLine($"For {entry} cans, your total is: ${entry * 2}");

Seems to work fine and, as far as I am aware, should work fine with if/else statements as well. But I'm quite new, so I don't know if this would create issues in different circumstances, or would be considered poor form, etc.

Thank you for your time!

It works fine for this example. But in a more sophisticated program you might want to keep the original reply string to use in possible error messages should the conversion fail.

That definitely makes sense. And I will say that, even by the end of this extremely simple cat food store program, I was already seeing how that might not be the best idea.

Thank you for your response!
