Introduction to Pointer Arithmetic in C (Pointer Math & Scaling) || C Programming || Lesson 118 ||
In this class we will have an Introduction to Pointer Arithmetic in C (Pointer Math & Scaling).
What happens when you add +1 to a pointer? It's not just simple math! In this deep-dive C tutorial, we explain the powerful concept of Pointer Arithmetic.
Learn how the compiler uses the data type (int, char, float) to "scale" the pointer's movement, allowing you to navigate through memory. We also cover the critical dangers of accessing invalid memory locations and why pointer math is the secret to understanding arrays.
