What is generic pointer in C?
When a variable is declared as being a pointer to type void it is known as a generic pointer. Since you cannot have a variable of type void, the pointer will not point to any data and therefore cannot be dereferenced. It is still a pointer though, to use it you just have to cast it to another kind of pointer first. Hence the term Generic pointer.
Trying to delete uninitialized pointer to object?
You cannot delete an uninitialized pointer, because there is no allocation for the object, and the pointer contains garbage. That includes the case where you attempted allocation and failed, but deletion is safe in that case because a NULL pointer is "safe" to delete, even though it does not point at anything.
How far does the pointer move when 4 unites of weight on thr spring?
The movement of the pointer on a spring scale due to a weight depends on the spring constant (k) and the weight applied. According to Hooke's Law, the displacement (x) is given by the formula ( x = \frac{F}{k} ), where ( F ) is the force applied (equal to the weight in this case). If the spring constant is known, you can calculate the displacement by substituting the weight (in this case, 4 units) into the formula. Without the spring constant, the exact movement cannot be determined.
How many pointers can be used in a c program?

What is pointer and use of pointer?
A pointer looks a bit like a stick. I use it to point at something. Read your text book, read C tutorials on the web and if you still cannot answer the question consider floor sweeping or basket weaving as a vocation.
