Explain why implicit numeric conversions are necessary and how C# chooses operands to convert.
What will be an ideal response?
When you perform arithmetic with variables of the same type, the result of the arithmetic retains that type. For example, when you divide two ints, the result is an int. Often, however, you need to perform mathematical operations on different types. For example, you might need to multiply an int by a double. In this case, C# chooses a unifying type for the result and implicitly converts nonconforming operands to the unifying type, which is the type with the higher type precedence. In the case of multiplying an int by a double, the result will be a double.
