The Java bytecode for access to the local variable array for a class is at most two bytes long. One byte is used for the opcode; the other indicates the offset into the array. How many variables can be held in the local variable array? What do you think happens when this number is exceeded?

Build a C program that performs the following operations: Declares three pointer variables called iPtr of type int, cPtr of type char, and fFloat of type float Declares three new variables called iNumber of int type, fNumber of float type, and cCharacter of char type Assigns the address of each non-pointer variable to the matching pointer variable Prints the value of each non-pointer variable Prints the value of each pointer variable Printer the address of each non-pointer variable Prints the address of each pointer variable

When asked, "What is a pointer variable?" What should we do now? That's because it's an array that changes on the go. Why are pointers and dynamic arrays problematic?

Using the Circle class defined in Q1, the following statements are coded in the main().                                Circle c1 = new Circle(); Circle c2 = new Circle(10); c1 = c2; Draw the memory allocation structure(s) for these instructions including the content values if possible.

What are the benefits and drawbacks of using decimal data types, as well as some strategies for making the most out of their application?

The code box below defines a variable route as a list of directions to navigate a maze. Each instruction is one of the following four basic commands: higher move one step in the positive y direction • lower. move one step in the negative y direction • left: move one step in the negative x direction • right: move one step in the positive x direction Define a function step that takes two arguments, a location (as a tuple of x and y coordinates) and an instruction (higher, lower, left, right) as a string. Given the provided location, it should return the new location (as a tuple of x and y coordinates) when following the specified instruction. If the instruction is invalid, the old location should be returned. Use the function step to determine the final position when starting from the point (0, -4) and following all instructions in the list route. Assign this final position to the variable final_point.
