import java.util.Stack;

/*

* A program which reads input from given text filename and prints

* whether it passed the pre-processing stage or not

* Sample input

* int A = (a + b);static void display(int x)

* {

* //A sample input file

Answer:

d. involves analyzing end-user business requirements in order to refine project goals

Explanation:

In the software development life cycle, the implementation stage is the stage where the computer programmers begin the actual coding of the application required by the end-user. At this stage, the developer takes into account the needs and specifications of the customer.

For example, if the end-user wants a software application that can track payment records, the researcher at this stage begins using the right software to code programs that can effect this function.

Lisa [10]

Answer:

Transport Layer

Explanation:

The transport layer which is responsible for end-to-end communication over a network. Transport Layer breaks the data, allocated by Application layer in smaller units called segments. It is used to number every byte in the segment. It is also responsible for error correction and provides reliability to the user. It allows the host to send and receive error corrected data, messages or packets  over a network and ensures  that data should be received in the same sequence in which it was sent.  It also enables multiplexing and flow control.
