1. pointer to a constant means you can not change what the pointer points to
2. constant pointer means you can not change the pointer.
There is no difference between them they are same rate constant is another name of specific rate constant
the difference between a constant in a graph and a constant in a experiment is that when on a graph, the constant is the thing that changes, and in a experiment it is the part that stays the same.
nothing
In contrast, for an ellipse it is the ''sum'' of these distances that is a constant
In an arithmetic sequence, the difference between any term and the previous term is a constant.
The former is variable, the latter is constant.
Pointer to constant *ptr=10 statement is invalid in pointer to constant i.e assigning value is illegal ptr++ statement is valid in pointer to constant. pointer can be incremented and decremented, Pointer is pointing to constant data object. Declaration: const int *ptr; Constant pointers: *ptr= 10 is absolutely valid in constant pointers i.e assigning value is perfectly legal ptr+++ statement is invalid in constant pointers. pointer can not be incremented or decremented. Declaration; int *const ptr;
A structure is a collection of primitives or other structures. A pointer is a memory address. Comparison of the two is like comparing bowling balls to cinder blocks. You can say that a structure defines the layout of the data, while a pointer points to data that is a particular structure.
Nothing, they are synonyms.
Acceleration is the difference between constant and non-constant motion.
The mouse pointer is called a cursor
Pointer holds an address Array holds values
There is no difference between them they are same rate constant is another name of specific rate constant
the difference between a constant in a graph and a constant in a experiment is that when on a graph, the constant is the thing that changes, and in a experiment it is the part that stays the same.
Generic pointer of type 'void *' is compatible with any (data-)pointer, but you cannot use the following operators on it: + - ++ -- += -= * -> []
There are four ways to declare a pointer: <type> * <name>; - a variable pointer to a variable type. const <type> * <name>; - a variable pointer to a constant type. <type> * const <name> {address}; - a constant pointer to a variable type. const <type> * const <name> {address}; - a constant pointer to a constant type. The last two declarations are constant pointers. Being constants, you must assign an address to them at the point of instantiation. Note that the 2nd declaration is a pointer to a constant, not a constant pointer. That is, the object being referred to is treated as if it were constant but the pointer itself is variable so we can still change the address, but not the value at that address.
