package body
Learn package body in Ada with a construct-specific explanation, unique example, engineering boundary, and mastery check.
package body is a focused Ada topic inside Program Structure. This lesson explains the construct itself, the state or value it operates on, and the observable result it produces.
Read the example as a small executable experiment. Identify the exact syntax that belongs to package body, then change one input and predict the result before running it.
Topic-specific example
package body Math is function Double(X:Integer) return Integer is (X*2); end Math;
package body has rules that are easy to miss when the example is copied mechanically. Check the feature-specific boundary shown by this construct: scope, mutability, evaluation order, type constraints, lifetime, error behavior, compile-time restrictions, or resource cleanup where applicable.
