Question
Which code provides the correct way to declare a function pointer?1 point(void*) function ();void () function (void data) = 12;void (*function)(int data);int * function();
Solution
The correct way to declare a function pointer in C/C++ is:
void (*function)(int data);
Here's the breakdown:
voidis the return type of the function.(*function)is the pointer to the function.(int data)is the parameter list of the function.
The other options are incorrect:
(void*) function (*)is not a valid syntax for declaring a function pointer.void (*) function (void data) = 12;is not a valid syntax because you can't assign an integer to a function pointer.int * function();is a function declaration, not a function pointer declaration. This declares a function that returns a pointer to an integer.
