If the base class constructor does not assign a value to an instance variable, the program compiles and runs correctly because the instance variables are initialized to their default values. This is because if an instance variable is not explicitly initialized, it is automatically initialized to a default value based on its data type. For example, integer variables are initialized to 0, floating-point variables are initialized to 0.0, and reference variables are initialized to null. Therefore, there will be no syntax, compile-time or run-time errors in this case.
