Answer:
A) True
Explanation:
Objects are known as reference types, meaning that they are always accessed by references, not copied. When a method is called, passing an object to it, Java passes a reference of that object to the method and when that reference is modified, the changes can be seen in the object itself. Therefore a mutable object can be mutated anywhere- either from where it is created or by a method it is passed to. Hence the need to always use privacy modifier keywords such as public, private or protected, to determine the exposure of class properties and methods.

See explaination
Explanation:
In our grammar for arithmetic expression, the start symbol is <expression>, so our initial string is:
<expression >
Using rule 5 we can choose to replace the nonterminal, producing the string:
<expression >*<expression >
We now have two nonterminals, to replace, we can apply rule three to the first nonterminal, producing the string:
<expression >+<expression>*<expression>
We can apply rule two to the remaining nonterminal, we get:
(number)+number*number
This is a valid arithmetic expression as generated by grammar.
Given a grammar G with start symbol S, if there is some sequence of production that when applied to the initial string S, result in the string s, then s is in L (G). the language of the grammar.
Answer:
Desired C++ Program with proper comment is given below
Explanation:
#include<iostream>
using namespace std;
//main function
int main()
{
int totalMiles = 0;
int remainingMiles = 0;
double amt = 0;
//taking input from user regarind total miles
cout<<"Enter the total miles: "<<endl;
cin>>totalMiles;
//if-else condition to do the calculation
if(totalMiles<=100)
{
amt = totalMiles*.25;
}
else
{
remainingMiles = totalMiles - 100;
amt = 100*.25 + remainingMiles*.15;
}
cout<<"The total amount is: "<<amt<<endl;
}
