Which of the following correctly declares a user- defined data type that defines a pointer to a float? typedef float * floatPtr; float* floatPtr ; typedef floatPtr* float typedef floatPtr *float;

The correct way to declare a user-defined data type that defines a pointer to a float is `typedef float *floatPtr;`. This line tells the compiler that `floatPtr` is a new type that can be used as an alias for a pointer to a float, simplifying your code and making it easier to read! One common mistake programmers make when using typedefs in C is not remembering that the new type can only use the type defined in the typedef declaration. For example, if you try to do something like `floatPtr = &myFloat;`, you need to ensure `myFloat` is indeed a `float` and not some other type. Always keep an eye on your types to avoid confusion!
