Acronym of DBLC:
The acronym of DBLC is “
Things that DBLC depict:
- DBLC is a sequential process which is used to trace the history of the application that is present within the
information system . - The history of the application can be traced from the beginning till its last even though being outdated.
- DBLC is concurrent to SDLC because the database represents the core of the information system.
- It is composed of six phases:
- Initial study:
- Examining the operations of the current system...

Write a program that reads a list of 10 integers, and outputs those integers in reverse. For coding simplicity, follow each output integer by a
space, including the last one. Then, output a newline.
Ex: If the input is:
2 4 6 8 10 12 14 16 18 20
the output is:
20 18 16 14 12 10 8 642
To achieve the above result, first read the integers into an array. Then output the array in reverse.

6.3B-2. Multiple Access protocols (2). Consider the figure below, which shows the
arrival of 6 messages for transmission at different multiple access nodes at times
t=0.1, 0.8, 1.35, 2.6, 3.9, 4.2. Each transmission requires exactly one time unit.

For the slotted ALOHA protocol, indicate which packets are successfully transmitted.
You can assume that if a packet experiences a collision, a node will not attempt a
retransmission of that packet until sometime after t=5.

You have the following IQueue interface. Implement a
Queue class derived from IQueue. You can use STL
containers discussed in class, such as vector,
queue, stack, deque, map.
#include
using namespace std;
class IQueue
{
public:
};
virtual void Enqueue(int val)
virtual int Dequeue() = 0;
virtual int Size() const = 0;
int main()

}
cout << q.Size() << endl;
q. Enqueue(10);
q.Enqueue(20);
q. Enqueue(30);
cout << q.Size() << endl;
cout << q.Dequeue() << endl;
cout << q.Size() << endl;

The measured speeds are supposed to be stored in a file, one number per line, as follows: 65.6 70.2 54.9 Unfortunately, due to an intermittent fault, occasionally multiple numbers are written on a single line as follows: 73.2 65.6 69.8 Furthermore, occasionally the radar gun outputs a single stray character such as: 67.9z, 6$4.9, or a3.9, to illustrate just a few. Given a file that has radar speed gun readings, write a function averageSpeed() to calculate the average of the numbers in the file. Your code must adhere to the following specifications: a. Prompt the user for the name of the input file to process. When the user enters a nonexistent file name, give the user a second chance. After two wrong entries in a row, quit the program with an appropriate message. b. Ignore numbers containing stray characters. Ignore any reading for slow vehicles moving at 2 miles per…arrow_forward
