Answer:

ifstream inputFile;

inputFile.open("Friends.txt");

Explanation:

Though, the programming language is not stated, questions like this are often from C++.

The first statement defines the ifstream object using the following syntax.

ifstream [object_name]

In this case, the object name is inputFile

So, the syntax becomes

ifstream inputFile;

The next line opens a file using the following syntax.

[object_name].open("Filename")

Here, object_name is inputFile and filename is Friends.txt

So, the open statement becomes

inputFile.open("Friends.txt")

What is probably the most revolutionary innovation since the printing press?

BARSIC [14]

Answer:

The Internet

Explanation:

Why? The internet has done twice if not thrice what the printing press has done. The printing press allowed for dissemination of information and knowledge to the population through its mechanical movable printing capability and speed of book publishing. However its reach was highly limited by the physical attributes of the machines and having to transfer books and papers in spreading them to certain destinations. This limitation has been eliminated by the internet as one is able to receive a book written today in seconds and not physically but through electronic means. In other words, information need not be transferred physically, also accessbility and cost of getting information has been highly improved with the internet.

Identify a syntax used to create a spinner control using an input element. a. b. c. d.

Lorico [155]

Answer:

Option A:

Explanation:

Spinner control is a graphical control element where user can adjust the value by pressing up or down arrow button. An example is given in the attached image.

In HTML, one of the key attributes we must use to create a spinner control is "step". The attribute "step" is required to specify the interval of the step value when user press the up or down arrow button.

If we set the attribute values as follows:

type = "number"
value = 2
min = 0
max = 10

The setting above will give a spinner control with a range of legal numbers between 0, 2, 4, 6, 8 and 10.
