I have a application about diagnosis and should determine the functional and nonfunctional requirement So can anyone help me with this question please: Is language considered as a functional requirement?
A functional requirement defines what the software is supposed to do. A non-functional requirement defines further expectations independent from the actual features.
Ex: functional requirement = "software should square the input value"
non-functional requirement = "software should use at max 1MB memory"
Note: This does not have anything to do with "Functional Programming"
