Answer:
Constants.
Explanation:
In some languages, it is possible to define special variables which can be assigned a value only once – once their values have been set, they cannot be changed. We call these kinds of variables constants.
Answer:
false
Explanation:
A reference parameter passed into the method can be changed by the method, when the method changes all of a parameter's variables, the parameter will keep the changes after the method is returned.
1. First normal form:
The first step in normalisation is putting all repeated fields in separate files and assigning appropriate keys to them.
2. Second normal form:
In this stage of normalisation, all non-key elements that are fully specified by something other than the complete key are placed in a separate table. Normally, these non-key elements are dependent on only a part of a compound key.
3. Third normal form:
This stage of normalisation enables eliminating redundant data elements and tables that are subsets of other tables. The redundant elements are those non-key data elements that are placed in more than one table of the virtual data elements.
Answer:
a. Sensitivity analysis
Explanation:
Sensitivity analysis determines how much an output would change with the variation of the input. This analysis is very important for integer linear programming because sometimes the large change in output can lead to undesirable, if not catastrophic results.
