Chapter 6, Problem 2.5SRE
Program Plan Intro
Scope:
- The portion of program that refers to the declared entity by its name is referred as scope.
- It refers to the lifetime and accessibility of a variable. If the variable is declared outside the class it is accessible to all the class methods.
- The scope of the parameter declaration is the body of the method in which the declaration appears.
- If the variable is declared within a method, then its scope is visible only inside the method and these variables cannot be accessed outside the method.

An argument is expressed in English below.
Rhys will go to the beach.
If Rhys is excited; then Rhys will go to the beach.
Rhys is excited.
Variable names are assigned to each English phrase as follows:
p: Rhys is excited
•q: Rhys will go to the beach
Is the argument valid? If valid, then indicate which rule is used for the
argument. If invalid, then give truth assignments to the variables that
prove the argument is invalid.

Code a JavaScript function called isLeapYear() that accepts one integer value as its parameter and will return true if this value is a leap year and false if it is not.
19.Rules: A leap year is divisible by four but not divisible by 100 unless it is divisible by 400.
E.g. 1600, 1912, 1996, 2000, 2020 and 2124 are leap years where 1000 and 3000 are not.

- In C# write a program to implement the logical operators such as not, xor, boolean and, boolean NOT to compute the result. The first step is the method. The method takes in two variables and computes a logical expression using them. Assigned parameters are called a and b. Find the Boolean NOT of a. Boolean XOR this with a itself. Find the Boolean AND of this answer with b. Return the Boolean NOT of the entire expression. Since we are returning true by default in the code in the code when you run the code, your code needs to pass ALL FOUR of our test cases to be considered correct.arrow_forwardGx: G(x) Gtrue bool Gfalse: bool Gn: int Gelt1 G,x: t1e2: t2 Glet x el in e2: t2 Gel bool Ge2 bool Gel and e2: bool Ge: int Gel bool Ge2t Ge3: t Geq0 e bool Gif el then e2 else e3: t Using the typing rules above, determine if the following expressions are well-typed:arrow_forwardChoose the Correct statement For light, we can call white a tertiary color because RED + BLUE + GREEN = WHITE.

- Java - Programming Develop a letter-guessing game in this assignment.Requirements:1). When the game begins, generate a random letter between A and Z;2). Display a message "I have a secret letter (A to Z), can you guess what it is?";3). Read the user's answer;4). Compare the user's answer and the random secret letter generated;5). If the user answer is before the random secret letter in the alphabet, display "Incorrect. Trysomething later in the alphabet" and go to Step 2;6). If the user answer is after the random secret letter in the alphabet, display "Incorrect. Trysomething earlier in the alphabet." and go to Step 2;7). If the user answer is the same as the random secret letter, display "Well done. Want to playagain (y/n)?";8). Read the user's answer. If the answer is 'y', go to Step 1. If the answer is 'n', go to Step 9;9). Display "Thanks for playing the game. Goodbye!". The program stops.Run your program several times. Take screenshots.

- Code using java programming language.arrow_forwardDeclaring a variable with only "type" is sufficient. You may use the data type and other properties of a variable to track it down. The next obstacle is developing a theory that can be used to characterise any variable.arrow_forwardFrog Contest On their way down the river, Jojo and Lili saw two frogs each in position X1and X2. The two frogs are seen jumping happily towards the same direction that is come to Jojo. After watching the two frogs, Jojo and Lili saw that the speed the two frogs are different. The first frog to start jumping from position X1 has a speed of V1, while the second frog that starts to jump from position X2 has a speed of V2. Jojo guess that "YES" both frogs will be in the same position in a certain time T, while Bibiguessing "NO" the two frogs will never be in the same position in timethe. Help Jojo and Lili calculate the frog's movements to determine whether the guess they are right. Input FormatThe first line of input consists of a series of integers namely X1, V1, X2, V2, T.X1 and V1 are the initial position and jump speed per second of the first frog.X2 and V2 are the starting position and jump speed per second of the second frog.T is the second when the frog jumps.
