Difference Between Integer and Pointer

Integer vs Pointer

‘Integer’ and ‘pointer’ are applied in most of the computer programming languages.

‘Integer’ in a programming language can be defined as any data type representing a mathematical subset. On the other hand, ‘pointer’ can be defined as a type that refers or points to another value which is stored in some part of the memory of the computer.

Integers exist mainly as binary value in a computer system. Integers mainly come in two types ‘“ signed and unsigned. Signed integers mean they represent negative integers, and unsigned integers mean they embody positive or non-negative ones. The common way of showing a positive integer is thorough a string of bits without any space or any other separator. Integers have value one zero and one only. They are just prefixed with the sign of + or -.

‘Pointer’ usually refers to a location in the memory. A pointer is also defined as a simple implementation or less subtracted of more abstract data. Though several languages support pointers, some languages have certain restrictions to pointers. These pointers really improve the performance for repetitive operations like looking up tables, traversing strings, tree structures, and control tables. As pointers allow protected as well as unprotected admission to the memory addresses, they are used to hold addresses of entry points. When talking of pointers, there are also risks involved when using them with unprotected access. It can also be said that pointers hold more addresses than the memory units in a system.
