the following is a legal c++ enumeration type: enum colortype {blue, green, pink, yellow, red}; true or false
A set of named values known as enumeration constants, which are integral constants, make up an enumeration, a data type.
Because you must list (enumerate) every value before giving it a name, an enumeration is also known as an enumerated type. Enumerations are helpful for variables that have a limited range of possible values because they give a mechanism to define and organize sets of integral constants.

The packet will first be sent to the default gateway, and then, based on the gateway's response, it can be routed to the destination host.
How are packets sent from the source to the destination?The management of packet transfer from a source machine to a destination is done by network layer protocol. Before being transmitted, data is divided into 64 kilobyte (kilo) packets, or datagrams, each of which is forwarded to the network gateway along with the destination IP address. To connect networks, a gateway may function as a router. Routers can use alternate interfaces to get to a destination if the network changes as a result of congestion or faults.

the value in a(n) ________ variable persists between function calls.
Although persistent variables are local to the function in which they are declared, their values persist across function calls.
What are persistent variables?Between function calls, persistent variables in a function will keep their current state.
This indicates that for Simulink, the values will be maintained from one time-step to the next.
Storing a target's position so you can alter it dynamically throughout a task is an illustration of how to use a persistent variable.
A persistent variable must be defined as such and initialized before it may be used. It must be initialized with caution to the appropriate size (i.e. the size that it will be used in that function).
The isempty(x) function can be used to determine whether the variable x has been initialized, and if not, you can take advantage of the opportunity to initialize the persistent variable.

A vending machine that serves coffee pours a varying amount of liquid into a cup with varying mass. Assume that the masses of the liquid and the cup are independent. Here are summary statistics for the masses of the liquid and the cups:.
The expected weight of a selected cup filled with liquid is T's mean. T has a mean value of 400.
The table's data is as follows:
Mean Standard Deviation
Liquid 250g 20g
Cup 150g 10g
The liquid is represented by L, and cup by C.
The following formula for expected value is used to calculate the mean of T.
E(L + C)
Because L and C are unrelated random variables,
E(L+C)=E(L)+E(C)
Where E(L) and E(C) are the mean liquid and cup values, respectively.
The equation is transformed into
E(L+C)=250g+150g
E(L+C)=400g
Hence, the mean of T is 400
In mathematics, particularly in statistics, there are several types of means. Each mean serves to summarise a given group of data, often to better understand the overall value (magnitude and sign) of a given data set.

3 Dynamic Programming: Car Ownership
In this question, we consider when it would be advantageous to sell the car you currently own and buy a new one. We assume that you have been given the following information from a "reliable" source:
p(i) the price of a new car in year i, for 1≤i≤n
(i, k) = the resale value of a car purchased in year i and sold in year k, for 1
• m(i, k) = the maintenance cost during year k of a car purchased in year i, for 1≤i≤ k ≤n.
The problem is to determine the years 11. 123, when you would purchase new cars such that the total cost of car ownership from years 1 through n is minimized. The total cost is the sum of the maintenance costs for years 1 through n plus the price of each car purchased minus the resale value of each car sold. In addition, you should make the following assumptions.
you don't have a car before year 1. (Since you have to buy a new car in year 1, 31 = 1.)
you only want to purchase new cars.
you are always able to sell your old car for v(i, k) dollars.
at the end of n years, you sell your last car for e(y,,n+1) dollars.
For example, if n = 10, 31, 325 and y=7, then this solution states that you should purchase a new car in year 1, buy the second car in year 5 and buy the third car in year 7. (You would also sell the first car in year 5, the second car in year 7 and the third car at the beginning of year 11.)
Questions:
a. Define a function, MinCost, that can be used to solve this dynamic programming problem. To do this, you must describe the input parameters to MinCost and its "return value" using English sentences. Note: describe the value that MinCost must return in relation to its parameters, not how to compute it, that's the next question.
b. Give a mathematical formula that shows how MinCost can be computed recursively. Then, explain the main parts of the formula in English.
c. Describe how MinCost can be computed bottom up using a dynamic programming table. Be sure to include a description of the dimensions of the table and the order that the entries of the table are to be filled. Which entry has the solution to the original problem?
d. State and briefly justify the running time of your dynamic programming algorithm.
We examine when it would be advantageous to sell the automobile you now drive and purchase a new one in Dynamic Programming: Car Ownership.

if (cars <= dayLimit)
t[day, cars] = 1;
} else // not first day
{
// okay, number of ways given amount of cars can be washed
// on certain day can be calculated using amounts possible on the previous day
for (int carsOnPrevDay = 1; carsOnPrevDay < cars; carsOnPrevDay++)

When is dynamic programming appropriate?When we have difficulties that can be broken down into smaller, related problems so that the solutions can be reused, we employ dynamic programming. These algorithms are typically employed for optimization. The dynamic algorithm will attempt to review the outcomes of the previously solved sub-problems before solving the current sub-problem.
What kinds of issues can dynamic programming solve?A highly helpful method for solving problems is called "dynamic programming," which divides a major problem into smaller, overlapping subproblems, stores the results of those computations, and then reuses those findings on larger portions of the problem.
