C# code for demonstrating ternary operator within return statement

public class BasicMathsCalculator
{
    public int BasicArithmeticOperation(int a , int b, string @operator)
    {
            return  @operator == "/" ? (a / b) :
                    @operator == "*" ? (a * b) :
                    @operator == "-" ? (a - b) :
                    (a + b); 
   }       
}

Here we are using ternary operator within return statement. If @operator = "/" then perform division, if @operator = "*" perform multiplication, if @operator = "-" perform
subtraction else if nothing is specified, perform addition.
