Chapter 11.1, Problem 11STE
Given the following definitions:
const int x = 17;
class A
{
public:
A( );
A(int x);
int f( ) const;
int g(const A& x);
private:
int i;
};
Each of the three const keywords is a promise to the compiler that the compiler will enforce. What is the promise in each case?

Assume each code snippet in each row below runs independently in a main function. For each one, say whether it's legal code or not. If it is, show the output and explain why it happens. If it’s illegal (e.g. syntax error), explain why. Try to do it without running the code, and then check and correct your answers as needed.

Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also, add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity.

- Evaluating Postfix Expression The Postfix notation is used to represent algebraic expressions. The expressions written in postfix form are evaluated faster compared to infix notation as parenthesis are not required in postfix. We have discussed infix to postfix conversion in the class. Write a Java program that will input a valid postfix expression. The expression may accept a whole number or a real number. Every operand and operator should be separated by a space.

The Problem class is used to help simulate a math fact, for example: 2+5= Your class needs to contain two constructors, one that takes String, int, int that represents the operator sign(+,-, *, or /), the minimum, and maximum values for the number range, and a second constructor that takes only a String that represents the operator sign. For the second constructor, the minimum should default to zero and the maximum to ten. Your Problem object should generate 2 random integers between the minimum and maximum values (inclusively). Each Problem object should only have one set of numbers that do not change. While you may include additional helper methods, two methods need to be available to the user. The first is the answer method that should return a double that represents the answer to the problem. The second is the toString that should return a String that represents the problem. The format should be: number…arrow_forward
