Each of the following heuristics helps make a good module according to some implementability or aesthetic principle. Identify the principle. (a) Minimize the number of operations in a class. (b) Eliminate irrelevant classes from your design. (c) Do not nest control structures more than seven levels deep. (d) Never make a class to do a job that a class in a standard library already does. (e) Eliminate duplicate code whenever you find it. (f) Provide get and set methods for all attributes in a class that clients might be interested in, even if they are not all used in the current program. (g) Do not reuse variables to hold different data. (h) Avoid operations with only a single line of code. (i) Keep operation parameters to five or less.

Nims is applicable to all stakeholders with incident related responsibilities. true or false

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."
