Chapter 7, Problem 1SA
Explanation of Solution
Array:
An array is defined as a group that consists of similar data types.
- The array size must be specified by an “int” value and not long or short.
- In Java, all arrays are allocated dynamically.
- An array is always indexed, starting from 0.
Example:
//Create an array variable with size 3
int i[] = new int[3];
In the above statement,
- The “int” refers the data type of the array.
- The “i” refers the name of the array.
- The keyword “new” refers the new memory allocation.
- The “int[3]” refers the size of the array.
Difference between array size declarator and subscript:
In the above example, “3” is the array size declarator and the index specified for each element in the array is called as subscript...

- Word Sleuth Puzzle Programarrow_forward1# Write a program that allows users to choose from one of three shapes: Squares, Circles or (right) Triangles. Allow the user to use the first letter of the shape (S, C, T) to specify what they want. After the shape is selected, ask the user for the appropriate data to calculate the shape's area, and then and print that area value to the screen for them. Area formulas you can use: Triangle: % base x height Square: length x length Circle: % Pl x radius? Notes: The floating-point data type will be your friend here. Round your area answer so that no more than 2 decimal places are shown when printing on the screen. You can use 3.1415 for Pl; Think about this as a CONSTANT in your code. For this part and especially part (b) below, think about componentizing your code. So one gigantic main() is not a best practice and not what we want to see here. Remember what we discussed about "procedural decomposition" and functions last week!arrow_forwardFundamentals of PHParrow_forward

The cube corners are labeled from 0 to 7 with 0 starting at the upper left-hand corner of the front face of the cube proceeding clockwise with corners 0, 1, 2, and 3 on the front face, and corner 4 being the upper left-hand corner of the rear face and proceeding clockwise with corners 4, 5, 6, and 7 on the rear face. (Note that computer scientists generally start counting at zero, rather than one, as the math calculations work out better. This will make more sense once we study 2 dimensional arrays.) You will need a delay function to slow down your code so the user can see Herman moving around the cube.
