Array in Go

Short summary

Go arrays are fixed-size, type-safe collections that automatically initialize all slots with zero values, preventing undefined-state bugs. This comprehensive tutorial covers multiple declaration syntaxes, element indexing, the len() and cap() functions, array copying behavior (value semantics), and using pointers to share array references—useful for developers learning Go fundamentals.

• •Arrays are fixed-size with automatic zero-value initialization
• •Multiple declaration methods: var, literal syntax, and the ... auto-size shortcut
• •Access/modify elements via indexing; use len() to get size
• •Arrays copy-by-value; use pointers for shared references
