What are called Parameters and write a note on Parameter without Type?
उत्तर
Parameters are the variables in a function definition and arguments are the values that are passed to a function definition.
Parameter without Type
Let us see an example of a function definition.
(requires: b > =0 )
(returns: a to the power of b)
let rec pow a b:=
if b=0 then 1
else a pow a*(b-l)
- In the above function definition variable ‘b’ is the parameter and the value which is passed to the variable ‘b’ is the argument.
- The precondition (requires) and postcondition (returns) of the function is given.
- Note we have not mentioned any types (data types).
- Some language computer solves this type (data type) inference problem algorithmically, but some require the type to be mentioned.
