Complete all steps of the Design Recipe to solve both of the problems below. We’ve provided a start to the first problem as a model.
Define a function called days-to-adopt, which computes the number of days it took an animal to be adopted by multiplying the number of weeks by 7. We’ve started both examples for you.
Contract and Purpose Statement |
Every contract has three parts…
days-to-adopt::Row->Number
_
Examples |
Write some examples, then circle and label what changes…
examples:
days-to-adopt (fixed-row) is 7 * fixed-row["weeks"]
days-to-adopt (unfixed-row) is 7 * unfixed-row["weeks"]
end
Definition |
Write the definition, giving variable names to all your input values…
fun _____________(_):
______________
end
Define a function called years-to-adopt, which divides the number of weeks by 52 to computes the number of years it took to be adopted.
