Answer:
float avg = 23.5;
Explanation:
Given
The declarative statements
Required
Determine which of them is invalid
<em>Analyzing them one after the other;</em>
int zebraCnt = 40000;
This statement is valid as zebraCnt is correctly declared as type integer
<em></em>
long birdCnt = 222_222_222_222_222L;
This statement is valid as birdCnt is correctly declared as type long
float avg = 23.5;
This statement is invalid as avg is incorrectly declared as type float.
<em>To correctly declare avg, you either change the datatype to double: as follows;</em>
double avg = 23.5;
or <em>append f to the declaration; as follows</em>
float avg = 23.5f;
double avg = 98.32121;
This statement is valid as avg is correctly declared as type double
Hence, the incorrect declarative statement is float avg = 23.5;

Software bought revolutionary change making entrepreneurs fortunate enough to make money in less time with least effort and
correct output. SDLC (Software development life cycle) is responsible for software’s reliability, performance, scalability,
functionality and maintainability. Although all phases of SDLC have their own importance but Software architecture serves as
the foundation for other phases of SDLC. Just like sketch of a building helps constructor to correctly construct the building,
software architecture helps software developer to develop the software properly. There are various styles available for software
architecture. In this paper, clear picture of all important software architecture styles are presented along with recent advancement
in software architecture and design phases. It could be helpful for a software developer to select an appropriate style according to
his/her project’s requirement. An architectural style must be chosen correctly to get its all benefits in the system. All the
architectural styles are compared on the basis of various quality attributes. This paper also specifies the application area,
advantages and disadvantages of each architectural style.
