C# Problem With a loop

[Redliquid]

Why doesnt my IF loop run?

The Code: http://codepen.io/Redliquid/pen/GgXKRP.html

 

The Result:



Why doesnt the If loop go to the first case which should be correct?

Just a random thought: after inputing from console try to put InputInt = InputInt - 13;

I never dealt with C#

Still goes to the Else part of the loop, why did you think it would change annything?

Because maybe it counts "Enter" towards input and converts it to int.

Try to output what InputInt value is.

Don't cast the input to an int. Best practice would be to use Int.Parse(input)

[Satlen]

change:

int InputInt = (int)Console.Read();

to:

int InputInt;int.TryParse(Console.ReadLine(), out InputInt);

[KuroSetsuna29]

When you do (int)Console.Read() that is actually getting the ASCII value of the string "1".

 

As xshockz suggested, you want int.Parse("1") or int.TryParse("1", out InputInt).

 

The difference is that int.Parse will throw exception if the string cannot be parse. Where as int.TryParse will return false, useful if you want to repeat until valid input.

Right, it should also change the output variable to 0 or null if the parse fails if I remember correctly.

Yes, from the MSDN:

 

 

result Type: System.Int32

When this method returns, contains the 32-bit signed integer value equivalent of the number contained in s, if the conversion succeeded, or zero if the conversion failed. The conversion fails if the s parameter is null or String.Empty, is not of the correct format, or represents a number less than MinValue or greater than MaxValue. This parameter is passed uninitialized.

This *should* do what you want it to.. also, you had no output after you added/subtracted the numbers.
