Introduction to User Defined Functions We have mentioned earlier that one of the strengths of C language is C User Defined Functions. They are easy to and use. We have used functions in every program that we have discussed so far. However, they define have been primarily limited the three functions, namely, main, printf, and

We have seen that a C program is a set of statements which are normally executed sequentially in the order in which they appear Decision Making. This happens when no options or no repetitions of certain calculations are necessary. However, in practice, we have a number of situations where we may have to change the

Design is a meaningful activity needed to develop a quality product. Software Design is the only way by which we can accurately translate the customer’s requirements into a finished software product or system. Thus design serves as the basis for all the software engineering steps. In this chapter we will get introduced with the systematic

Introduction Software Testing People are not perfect. We make errors in design and code. Hence testing is an essential activity in software life cycle. The goal of testing is to uncover as many errors as possible. The software testing is an important activity carried out in order to improve the quality – the software testing.

In software requirements engineering there is a systematic use of principles, technique and tools for cost effective analysis, documentation and user needs. Both the software engineer and customer take an active role in software requirements engineering. In this chapter e will discuss the concept of user and functional requirements. We describe functional and non functional
