why is this true? Very thankful for any help :)

int age; bool can_drink; Console.Write("Enter your age: "); age=Console.Read(); can_drink=(age>=21)? true:false; Console.Write(can_drink); input(3) Output: true :/

Thank you all, especially Sachin! Why does the conversion affect the output?

To David, when I entered 22 it was still true. I even entered negative numbers, and it still evaluated to true. I tried Sachin's method, worked like a charm :), though I don't know why

I somewhere read that, only the use of- Console.Read() ot Console.ReadLine() takes input as a string, but here you need integer, that's why I convert the input into integer using- Convert.ToInt32()

Try this- int age; bool can_drink; Console.Write("Enter your age: "); age= Convert.ToInt32(Console.ReadLine()); can_drink=(age>=21)?true:false; Console.Write(can_drink);

To all the people who are confused as to why that fixes the problem. I THINK it's because ReadLine() returns a string. So you have to convert/parse that string to get an int out of it.
