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.

The equation of a line in standard form is ax + by = c , wherein both aand b cannot be zero, and a, b, and c are real numbers. If b≠0, then –a/b is the slope of the line. If a = 0, then it is a horizontal line, and if b = 0, then it is a vertical line. The slope of a vertical line is undefined. Two lines are parallel if they have the same slope or both are vertical lines. Two lines are perpendicular if either one of the lines is horizontal and the other is vertical or the product of their slopes is –1. Design the class lineType to store a line. To store a line, you need to store the values of a (coefficient of x), b (coefficient of y), and c. Your class must contain the following operations:
If a line is nonvertical, then determine its slope.
Determine if two lines are equal. (Two lines a₁x + b₁y = c₁ and a₂x + b₂y = c₂ are equal if either a₁ = a₂, b₁ = b₂, and c₁ = c₂, or a₁ = ka₂, b₁ = kb₂ and c₁ = kc₂, and for some real number k.)
Determine if two lines are parallel.

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.

Let the following symbols represent the corresponding statements: uv - There is an undeclared variable. se - There is a syntax error in the first five lines. ms - There is a missing semicolon. vm - There is a misspelled variable name.

- 1. The operator ↑ is complete. In other words, all the three operators -, V and A are representable by using ↑ only.arrow_forwardIn CORAL LANGUAGE please and thank you! Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 Hint: Find the smallest value, and then subtract it from all three values, thus removing the gray.arrow_forwardJava Script There is a single operator in JavaScript, capable of providing the remainder of a division operation. Two numbers are passed as parameters. The first parameter divided by the second parameter will have a remainder, possibly zero. Return that value. Examples remainder(1, 3) → 1 remainder(3, 4) → 3 remainder(-9, 45) → -9 remainder(5, 5) → 0 Notes The tests only use positive and negative integers. Don't forget to return the result.arrow_forward
