PLEASE HELP ME SOLVE THIS QUESTION

Answer 1

Answer:

​​​​​​Q.2.1 Sentinel - c.value that stops a loop

Explanation: In any programming language,Sentinel is value which is used to terminate the loop.

Q.2.2 Flag - g.A variable that holds an indicator of whether some condition has been meet.

Explanation: Flag is boolean variable which holds true(1) and false(0).If the condition meets Flag is 1 otherise it is 0.

Q.2.3 Char Datatype - f.value that holds any single character.

Explanation: In the programming languages,datatypes are used to hold the data of the particular type.int datatype holds Integer value and float datatype is used to hold floating point value likewise char datatype is used hold single character.

Ex: char str='a';

Q.2.4 Parameters - b.Arguments in a method call

Explanation: In the Functions(Methods) we pass parameters which are nothing but arguments to pass information(data) to the method.

Q.2.5 Dead Code - l.Set of statements that are logically unreachable.

  Explanation: In the programming languages,Dead code is when we cannot reach those statements which are not at all reachable in any case.

Q.2.6 Applets - d.Programs embedded in a Web Page.

  Explanation: Applet is an java program which is embedded in web browser using APPLET OR OBJECT to run.

Q.2.7 Ambiguous - a.When the compiler cannot determine which method to use.

  Explanation: In programming languages,Methods are having same names at that time compiler does not which method to execute.In grammers in theory of computation also Ambiguity is there.

Q.2.8 Buffer - k.Block of memory.

  Explanation: Buffers means storing of temporary data when a particular transfer occurs.

Q.2.9 Accesor - h.Retrieve values.

  Explanation: Accessor methods are also known as getter methods.The private variables are retrieved by getter methods.

Q.2.10 Mutator - i.Set values.

  Explanation: Mutator methods are also known as setter methods.The private variables had set the values by using the setter methods.

The remaining Column B descriptions are not matched with the terms in Column A.

The description "e.Virtual machine" does not relate to any term in Column A because virtual machines provide the functionality of computer.So it does not match.

The description "j.Indicates one of the arrys's elements" does not relate to any term in Column A beacuse To indicate any element we use the array name with index.So it does not match.

Hope you understand and like the answer.

Thank you..
