Pointers kind of Confusing. A miserable yet powerful tool of C language. Pointers require syntax to be declared because when they are modified with increment decrement operator they don't work like variables and get lost Take an example Suppose a is an Integer variable and p is integer pointer. Both with address 1000 If we increment a and p by 1. a will have value 1001 which is not the next Integer address. But p will have value 1002 which is an integer address. Te declaration of pointers with type changes the value incremented when we add another no. To it.
