default parameters

Learn default parameters in Ada with a construct-specific explanation, unique example, engineering boundary, and mastery check.

10 min read • Intermediate

default parameters is a focused Ada topic inside Subprograms. 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 default parameters, then change one input and predict the result before running it.

Topic-specific example

ada Try It Live 
procedure Log(Msg:String; Level:Integer:=1) is begin null; end;
Edge case / engineering note

default parameters 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.
