Mastering C++: A Comprehensive Quiz Based on 'Thinking in C++

C++ compilers disallow assigning a void pointer to another type of pointer without a cast in order to prevent type mismatches and potential errors. This is because void pointers do not have a specific data type associated with them, and therefore, they can be used to point to any type of data. However, attempting to assign a void pointer to a different type of pointer without a cast can lead to unexpected data conversions and possible errors at runtime. This type checking ensures that the code is more reliable and less prone to errors. The other options are incorrect because enforcing object-oriented principles or making the code more complex are not the primary reasons for disallowing this in C++. Additionally, it is not true that C++ does not disallow this as seen in the correct answer.
