Consider the clipping of a line segment in two dimensions against a rectangular clipping window. Show that you require only the

Semmy [17]

Answer / Explanation:

Assuming we define the end points as ( x₁ , y₁) and (x₂ , y₂) and the rectangular window edge as ( Xmin ,Ymin and Xmax , Ymax)

The illustration of the above assumption is represented in the diagram below.

Now, suppose the line segment is between the points P₁ = ( x₁ , y₁) , and

P₂ = (x₂ , y₂).

We can then create a line recalling and using parametric form,

P(t) = ( 1 - t) P₁ + tP₂ , t ∈ {0 , 1 },

So, for the X axis, we have,

tₓ = P₁ₓ - x ÷ P₁ₓ - P₂ₓ

We need to note that at this point we need to know the minimum and maximum unclipped values for parameter t from each dimension.

Therefore,

- ( tmin , tmax ) = ( 0,1) means unclipped line

-tmin > tmax means completely clipped out line

– Some other range means partially clipped out line.

Write a public member function which replace that replaces one occurrence of a given item in the ArrayBag with another passed as

ira [324]

Answer:

The method is written in Java

public static boolean abc(int [] ArrayBag,int num, int replace){

Boolean done = false;

for(int i =0; i<ArrayBag.length;i++){

if(ArrayBag[i] == num){

ArrayBag[i] = replace;

done = true;

}

for(int i = 0;i<ArrayBag.length;i++){

System.out.println(ArrayBag[i]+" ");

}

return done;

}

Explanation:

The method is written in java

The arguments of the method are:

1. ArrayBag -> The array declares as integer

2. num -> The array element to check the presence

3. replace - > The replacement variable

This line defines the method as boolean.

public static boolean abc(int [] ArrayBag,int num, int replace){

This line declares a boolean variable as false

Boolean done = false;

The following iterates through the elements of the array

for(int i =0; i<ArrayBag.length;i++){

This checks if the array element exist

if(ArrayBag[i] == num){

If yes, the array element is replaced

ArrayBag[i] = replace;

The boolean variable is updated from false to true

done = true;

}

The following iteration prints the elements of the array

for(int i = 0;i<ArrayBag.length;i++){

System.out.println(ArrayBag[i]+" ");

}

This prints returns the boolean thats indicates if replacement was done or not.

return done;

}

Attached to this solution is the program source file that includes the main method of the program

yawa3891 [41]

Answer:

Create partitions on each hard disk drives.
Mount the partition created on each hard drive so they are accessible by the the operating system.
Format the partitions created with a filesystem recognized by Linux.

Explanation:

Having purchased the two new SCSI hard disk drives with the controller cards for each and installed them properly, before using them for data storage and retrieval he must first use the fdisk command to create one or more partitions on each of the hard disk drives then mount any partitions created on the two hard drives so that they are accessible by the operating system before then proceeding to format any partitions created with a valid filesystem recognized by Linux.
