Answer:
/*
* Program to print traingle using asterisk.
*/
#include<iostream>
using namespace std;
//Function to print n asterisk in a row.
void printAsterisk(int n)
{
for(int i = 0;i<n;i++)
cout<<"*";
}
int main()
{
//Variable to store size of trianle
int size;
cout<<"Enter the size of triangle"<<endl;
cin>>size;
//print asterik in increasing order line by line.
for(int i =0; i<size;i++)
{
printAsterisk(i);
cout<<endl;
}
//print asterik in decresing order line by line.
for(int i =size-1; i>0;i--)
{
printAsterisk(i-1);
cout<<endl;
}
}
Output:
Enter the size of triangle

Explanation:
Since no programming language is mentioned therefore answer is provided in C++.
The above program will use two for loops to print the triangle using asterisk.
The first loop will print the asterisk line by line with each line having one more asterisk than the previous one till the size of the triangle.
The second for loop will print the asterisk using same logic as above but in reverse order.
Final output of triangle will be obtained.
Answer: D)XBRL(eXtensible Business Reporting Language)
Explanation: XBRL(eXtensible Business Reporting Language) is the type of XML(eXtensible Markup Language) that is used for the improvement in the transparency between the recipient and the business organization regarding the accessibility of the financial information.
The financial data is formatted uniformally so that the user can get the knowledge about the finance through the online sources like internet.
Other options are incorrect because HTML and XML are the markup languages but not for the financial area and PDF file is the file that stores data.Thus correct option is option(D).
Answer:
disk caching
Explanation:
Hi,
Magnetic hard drives use disk caching to speed up performance. This method is quite ingenious because what it does is that in a section of memory in your pc, it keeps a copy of information that was previously accessed in the hard disk. So, next time if the same data is requested, the system can refer to cache to get quick access rather than going to the hard disk (which is slower).
