It is the user tier of the 3-tier architecture that consists of computers, phones, and other mobile devices that have browsers that request and process web pages.
Explanation:
Almost if not all applications that use e-commerce for operations use the 3-tier architecture.  3-tier architecture is simply the arrangement of server tier which consists of all computers that run a web server and a database tier that consists of computers that run a DBMS to store and retrieve data. We also have the user data that consists of computers, phones, and other mobile devices that have browsers that request and process web pages.
When you make a request, for instance to Google in your local browser, the browser sends a request to the internet. This initial interaction between the user and the internet is what is known as the user tier of the 3 tier architecture. Basically, it is the phase where end users access content online through graphical interface browsers and make requests to the web servers and DBMS.

Answer:
The correct answer is:
C. ndx = 0;
while (ndx < 3) {
ar[ndx] = 0;
ndx++;
}
Explanation:
The declaration given is:
int ar[3];
This means the array consists of three locations and is named as ar.
We know that the indexes are used to address the locations of an array and the index starts from 0 and goes upto to 1 less than the size of the array which means the indexes of array of 3 elements will start from 0 and end at 2.
Now in the given options we are using ndx variable to run the while loop.
So the code to assign zero to all elements of array will be
ndx = 0;
while(ndx<3)
{
ar[ndx] = 0;
ndx++;
}
Hence, the correct answer is:
C. ndx = 0;
while (ndx < 3) {
ar[ndx] = 0;
ndx++;
}
