NPTEL Software Engineering Week 1 Assignment Answers 2022
1. The goal of structured programming is which the following:
a. To have well indented programs
b. To be able to infer the flow of control from the compiled code
c. To be able to infer the flow of control from the program source code
d. To avoid the use of GO TO statementse.
e. To have modular programs
Answer:- d, e
2. Unrestricted use of GO TO statements is normally avoided while writing a program, since:

e. It increases the effort required to adequately test the software
Answer:- d, e
3. Which of the following are true of a model in the context of software development?

b. A model captures only important aspects of the problem and ignores the rest.
c. Different models are obtained when different aspects are ignored.
d. A model is essentially a decomposition of the system
e. A model helps handle the complexity in problem solution
f. A model is essentially a design of the system
Answer:- a, b, c, e

a. Difficulty in permanently remembering large amount of information.
b. Difficulty in developing a program with large number of variables
c. Difficulty in debugging a program with large number of variables
d. Difficulty in understanding a program with large number of variables
e. Difficulty in understanding a design in which each module is decomposed into a large number of modules
f. Difficulty in understanding a design in which a function calls a large number of other functions
g. Difficulty in understanding a design in which a function is called by a large number of functions
h. Difficulty in understanding a design in which a module is reused in many modules
Answer:- g, h
9. While using the exploratory development style, the effort required to develop a software grows exponentially with the size of the software. Which one of the following is a possible reason behind it?
a. Testing effort increases exponentially
b. Code size becomes exponentially large
c. As the number of independent variables in the program increases, it quickly exceeds the grasping power of an individual.
d. As the size of a program increases, it becomes very difficult to correct compilation errors.
e. As the size of a program increases, program compilation takes an unduly large amount of time.
Answer:- c
