The <u>control class</u> acts as a switchboard between the view layer and the domain layer.
Explanation:
As the name suggests, the control class is responsible for performing the control actions. The view layer defines the entities and attributes which have to be viewed and their structural organization.
The domain layer consists of all the entities, attributes, and relations in the data. The control class controls the flow of information between the two layers and performs the operations of filtering and selecting the content to be displayed.
Answer:
laser
Explanation:
These are well known printer types now. Let's review how they work to determine in which does heat plays a role.
inkjet: inkjet printers are printer throwing ink at the paper in the form of little drops. No heat involved here.
impact: That's the oldest technology, where a printing head is moving left and right to punch a printing ribbon and transfer ink onto the paper. No heat involved.
3D: 3D printers don't usually use paper... as they use other materials to create a 3D representation of a model. Heat is involved in the melting of the material before it's placed on the building model. But no paper involved here.
laser: laser printers are working very much like a photocopier machine... memorizing the pattern to be printed, then transferring it onto paper... using heat.
Answer:
a) Global
Explanation:
The scope of a variable declared outside of any function is Global.
Let us consider an example:
int g;
int add(int a,int b){
return a+b;
}
int subtract(int a,int b){
return a-b;
}
Here the variable g is defined outside any function and is accessible anywhere within the program. This is a global variable.
Variables defined within each function - a,b on the other hand have a local scope are are visible only within their respective function bodies.
