pointer arithmetic
This term is highly specialized technical jargon used primarily in low-level programming languages like C and C++. It describes a method of memory navigation that treats memory addresses as numeric values, allowing a developer to jump to specific data locations by adding or subtracting offsets.
Because this practice bypasses the safety checks found in higher-level languages, it is often associated with high performance but also with significant security risks, such as buffer overflows. In modern software engineering, it is frequently contrasted with array indexing, which is generally considered safer and more readable.
