The Architecture of Pointers
Section 1 of 5
Before you can build complex lists, you must understand the "bookmark" system of computer science. Pointers allow us to create dynamic relationships between scattered memory blocks.
A Pointer is a variable whose value is the address of another variable in memory.
"Think of your computer memory like a massive hotel. A regular variable is the **guest** inside room 402. A pointer is the **door key** with '402' written on it. The key doesn't contain the person, but it gives you access to whoever is inside."
Stores atomic values (int, char, float)
Stores 64-bit hexadecimal addresses
Hexadecimal Mapping
Memory is reserved in a single continuous block.
Memory is scattered; pointers provide the "map".
int x = 42;Memory is allocated and a value is stored directly.
