Definition
In computer programming, zero-indexed language refers to systems where counting starts from 0 instead of 1 when accessing elements in an ordered collection (e.g., arrays).
An array is an ordered collection of elements stored in contiguous memory locations. Each element can be accessed using its index.
Index out of bounds: This term refers to trying to access an element outside the valid range of indices for a given data structure, resulting in an error.
Loop: A loop is a programming construct that allows executing a set of instructions repeatedly until a specific condition is met. It often involves iterating over elements in an ordered collection using their indices.
