How to find an input which is not a DataType?

Question

I'm getting an user input from user,
Since if they type 2 means it will print integer, for 13.2 it will print float, for true it will print bool and for "name" it will print string,

Now if they type %& likee that symbols means it will output not datatype, how should I Do that?

Answer 1

This is a tricky one, there is a lot that can be a string.

%& is technically a string
The discount is 5% is a valid string
The brown fox and lots of other words are a string.

Have a look at
Char.IsSymbol method
and there are lots of other Char.Is...... methods

know that you can iterated through a string with
string input = "hello";
foreach(char c in input)
{
if (Char.IsSymbol(c))
{
Console.WriteLIne("char is symbol");
}
else
{
Console.WriteLIne("char is not a symbol");
}
}

Answer 2

sneeze if I write else means it will not print "string" since I have given final ="string" at top and if condition as
if(!string.IsNullOrEmpty(o)){

....

}

Answer 3

if () // one statement
{
}
else if() // as many as you like, even no else if is allowed
{
}
else //one statement, or no else at all
{
}

you can write

else
{
final = "not datatype";
}
