Array: An array is a data structure that stores a fixed-size sequence of elements of the same type. It allows for efficient storage and retrieval of multiple values using indexes.
Element: An element refers to an individual value stored within an array or collection. Each element has its own unique index that determines its position within the data structure.
Index Out-of-Bounds Error: An index out-of-bounds error occurs when you try to access or modify an element using an invalid index (outside the valid range). It can result in runtime errors or unexpected behavior.
