Answer:
Option B and C are the correct answer for the above question
Explanation:
The above question asked about the work of the programmer to catch an error of the program--
- Then the option B states that the programmer needs to prints the value of the various program variable on every line of the program which is the correct solution because it is used to find the error easily. It defines the value of every variable in every place of the program and the programmer caught the error statement in the program if anywhere the variable gets the false value.
- The C option states to help from a friend, it is also a good solution because the friend can easily be caught the error of the program by seeing every line of code.
- But the other option is not correct because the option A states that the change the name of the variable which is not a result of anything.
- And the option D states that the code will be retyped again which is also not justify anything.
Answer:Sequence diagrams
Explanation: Sequence diagram is the diagram that displays about the connection of the objects in a sequential manner. The sequence depicted through the vertical lines in parallel form was about the object function and the horizontal line showed interaction between them for the exchange of the information.
Other options are incorrect because structural models have the infrastructure in particular format, communication diagrams depicts the exchange of information through communication and class diagram is the diagram that displays the system's class.Thus the correct option is sequence diagram.
