Answer:

The correct answer is A.

Explanation:

B is true if the two nodes are descending from the same parent node, they are called sibling nodes.

C is true, the nodes which do not have any nodes branching from them are called leaf nodes and mark the end of that specific branch.

D is true, a node tree is defined as nonlinear set of nodes growing downwards which are linked together.

The false option is A, a node in a node tree does not have to contain at least two links, it can be a leaf node.

I hope this answer helps.

Using C#, declare two variables of type string and assign them a value "The "use" of quotations causes difficulties." (without t

stich3 [128]

Answer:

Let the two string type variables be var1 and var2. The value stored in these two variables is : The "use" of quotations causes difficulties.

The variable which uses quoted string:

string var1 = "The \"use\" of quotations causes difficulties.";

The variable which does not use quoted string:

string var2 = "The " + '\u0022' + "use" + '\u0022' + " of quotations causes difficulties.";

Another way of assigning this value to the variable without using quoted string is to define a constant for the quotation marks:

const string quotation_mark = "\"";

string var2 = "The " + quotation_mark + "use" + quotation_mark + " of quotations causes difficulties.";

Explanation:

In order to print and view the output of the above statements WriteLine() method of the Console class can be used.

Console.WriteLine(var1);

Console.WriteLine(var2);

In the first statement escape sequence \" is used in order to print: The "use" of quotations causes difficulties. This escape sequence is used to insert two quotation marks in the string like that used in the beginning and end of the word use.

In the second statement '\u0022' is used as an alternative to the quoted string which is the Unicode character used for a quotation mark.

In the third statement a constant named quotation_mark is defined for quotation mark and is then used at each side of the use word to display it in double quotations in the output.
