Answer:
Following are the program in C++ language
#include <iostream> // header file
using namespace std; // namespace
int main() // main function
{
int number=0; // variable declaration
while(number>-1) // iterating the while loop
{
cout<<"body"<<endl; // dsiplay the statement
cin>>number; // Read the value by the user
}
cout<<endl<<"Done";// dsiplay the statement
return 0;
}
Output:
body
5
body
45
body
-8
Done
Explanation:
Following are the description of the statement
- Declared a variable "number" of int type and initialized with 0 to them
- iterating the while loop. In this loop print the message "body" and Read the value by the user in the "number" variable. This loop will be executed repeatedly until the user do not read the negative value.
- After the execution of the while loop, it prints the message "Done".
<u>Output:</u>
f1 in A
f2 in A
f1 in B
f2 in A
f1 in A
f2 in A
f1 in B
f2 in B
<u>Explanation:</u>
In this snippet, the code makes use of virtual functions. A virtual function is defined as a function that is defined in the base class and redefined in the derived class. If the derived function accesses the virtual function, the program will get executed with the derived class’s version of the function.
In this code, we define the virtual function f1() in class A and also redefine it in class B which is the derived class of A. While executing the program, the function g which takes the object b (class B’s object) as a parameter. It will print class B’s version of f1() rather than class A’s version. This is working off the virtual function.
Answer: Business intelligence
Explanation:
Most of the enterprises and organizations collects huge amount of data through the use of MIS. These data can be based on any aspect of the business. But the collection of such large sets of data is useless until and unless there is a business intelligence associated with it. the work of business intelligence is to use software tools for analysis of the collected data so that it could be useful for enterprise or company to look for patterns and trends in the market.
The outcome of such business intelligence is very helpful particularly to managers, executives for taking particular decisions in the greater interest of the company.
So we can say, business intelligence is an approach to boundary spanning that results from using sophisticated software to search through large amounts of internal and external data to spot patterns, trends, and relationships that might be significant.
