1.Differentiate pure and impure function.(11)
| Pure Function | Impure function |
|---|---|
| The return value of the pure functions solely depends on its arguments passed. Hence, if you call the pure functions with the same set of arguments, you will always get the same return values. They do not have any side effects. | The return value of the impure functions does not solely depend on its arguments passed. Hence, if you call the impure functions with the same set of arguments, you might get the different return values For example, random(), Date(). |
| They do not modify the arguments which are passed to them | They may modify the arguments which are passed to them |
2.Why strlen is called pure function?(2)
strlen is a pure function because the function takes one variable as a parameter, and accesses it to find its length. This function reads external memory but
does not change it, and the value returned derives from the external memory accessed.
