Answer:
The Variable is out of scope
Explanation:
In programming variables exists with scopes This could be local or global. When a variable is declared as a global variable it is available to all methods and procedures in the program. Java programming language as well as C++ and several others use the open and close braces to define the scope in programs. consider the following example
<em>public class ANot {</em>
<em> public static void main(String[] args) {</em>
<em> int i = 0;</em>
<em> while ( i<10){</em>
<em> int sum = 0;</em>
<em> sum = sum+i; </em>
<em> }</em>
<em> }</em>
<em>}</em>
In this example, the variable i is global and can be assessed within the while loop but the variable sum is local to the while loop and cannot be assessed outside of it
Answer:
Option (b) is the correct and suitable answer for the above question.
Explanation:
The printer is a hardware which is used to convert the soft copy of an information to a printed copy (Hard copy) of information.
To use printer hardware a computer system needs a printer driver which is used to do the conversion from soft copy to a hard copy. Hardware printer uses only for the purpose to print the copy.
The option b says that the printer driver is used to convert the document into the form of that document which the printer can understand easily. It means conversion from soft copy to hard copy. Hence it is the right option.
The reason behind the other option which is not valid because--
Option a says that the printer driver is a code but it is a software.
Option c says that the printer driver is an interface but it is a software.
Option d says that the printer driver is a cache but it is a software.
