Introduction to Pointer Arithmetic
Moving Pointers
You can use arithmetic operators like addition (+) and subtraction (-) with pointers to navigate through memory locations. When a pointer is pointing to an int, increasing its value will move it forward by the size of an integer.
The size of the data type to which the pointer points determines the step size of the arithmetic operation. You can experiment with different data types.
main.cpp
Pitfalls and Memory Safety
Performing multiplication or division directly on pointers will result in an error. Additionally, using float numbers with pointers is generally not meaningful and can lead to unexpected behavior.
Be caution
Accessing memory beyond the allocated bounds, often due to incorrect pointer arithmetic, can lead to serious issues such as crashes and security vulnerabilities.
