What will be the data type of the expression (a < 50) ?var1 : var2; provided a = int, var1 = double, var2 = floatinffloatdoubleCannot be determined

The data type of the expression (a < 50) ? var1 : var2; will be determined by the ternary operator ? :. This operator returns one of two values depending on the result of an evaluated condition. If the condition a < 50 is true, then the expression will have the same data type as var1, which is double. If the condition is false, then the expression will have the same data type as var2, which is float.

However, in many programming languages, when a double and float are used in the same expression, the float is typically promoted to a double to perform the calculation, and the result is also a double. This is because double has a higher precision than float.

So, the data type of the expression (a < 50) ? var1 : var2; will be double.
