Consider the following program, written in JavaScript-like syntax: //main program var x, y, z function sub1(){ var a, y, z; …………. } function sub2(){ var a, b, z; …………… } function sub3(){ var a, x, w; …………… } Given the following calling sequences and assuming that dynamic scoping is used, what variables are visible during execution of the last subprogram activated? Include with each visible variable the name of the unit where it is declared. main calls sub1; sub1 calls sub 2; sub2 calls sub3. main calls sub1; sub1 calls sub3; sub3 calls sub2. main calls sub3; sub3 calls sub2; sub2 calls sub1.
In java and UML diagram, Please show output and comment code out Source file: Each public class must be contained in a separate Java source file. Only one source file will have a main() method and this source will be named BlackjackGameSimulator.java. Other source/class names are up to you following the guidelines specified so far in the course. The format of the Java source must meet the general Java coding style guidelines discussed so far during the course. Pay special attention to naming guidelines, use of appropriate variable names and types, variable scope (public, private, protected, etc.), indentation, and comments. Classes and methods should be commented with JavaDoc-style comments (see below). Please use course office hours or contact the instructor directly if there are any coding style questions. JavaDocs: Sources should be commented using JavaDoc-style comments for classes and methods. Each class should have a short comment on what it represents and use the @author…
Implement in C programming language Question 1 Write a program in c to detect if the system will face any deadlock in the future. If a deadlock is detected then print “Deadlock Ahead” otherwise print “Safe here”. The situation is given below. (Allowed to use Banker’s Algorithm). Note: The code can be implemented in several different ways, but make sure the parameter remains the same as shown below. n = 5; // Number of processes m = 4; // Number of resources int alloc[5][4] = { { 0, 1, 0, 3 }, // P0 // Allocation Matrix { 2, 0, 0, 0 }, // P1 { 3, 0, 2, 0 }, // P2 { 2, 1, 1, 5 }, // P3 { 0, 0, 2, 2 } }; // P4 int max[5][4] = { { 6, 4, 3, 4 }, // P0 // MAX Matrix { 3, 2, 2, 1 }, // P1 { 9, 1, 2, 6 }, // P2 { 2, 2, 2, 8 }, // P3 { 4, 3, 3, 7 } }; // P4 int avail[4] = { 3,…
What is the purpose of using a virtual machine to represent the execution environment of a Java class? The distinction between this virtual machine and a real-world computer that runs C code is explained in detail below.
Write a simple java program with the following specifications: In the main method add the following declarations: int[ ] arr1 = {1,2,3,4,5,6,7,8,9,10}; int[ ] arr2 = {10,9,8,7,6,5,4,3,2,1}; int[ ][ ] arr3 ={{1,2,3},{4,5,6},{7,8,9},{10}}; System.out.print(arr1[0]); Save, compile and run the program. 1: What is the output when you run the program? 2: What is the value of: arr3[arr1[0]][arr2[arr1[8]]] 3: What is the value of: arr3[2][arr1[1]] 4: What is the value of: arr1[arr2[arr1[arr2[3]]]] 5: What is the value of: arr1[x++] 2.

USE JAVA LANGUAGE to solve this problem Important:- Provide API documentation comments for your class(es), class constructor(s) and method(s) using the Javastandard form for documentation comments discussed in this course.- Use meaningful variable and constant names
Exercise 6 Suppose that AYBU is a new programming language that is similar to C, except that AYBU uses dynamic scoping. Consider the program below. What is the output of the program when it is: /////////////////////////////////////////////////////////////////// int i=25; void A(void) { printf("A1: %d \n",i); i--; printf("A2: %d \n",i); } void C(){ static int i = 99; i--; printf("C1: %d\n",i); } void B(int i) { printf("B1: %d\n",i); i-=10; A(); printf("B2: %d\n",i); C(); printf("B3: %d\n",i); } int main(int argc, char** argv) { int i=100; printf("M1: %d\n",i); B(i); printf("M2: %d\n",i); A(); printf("M3: %d\n",i); C(); return 0; } (a) Compiled with a normal C compiler?

Microsoft and Sun have had public conversations over the design of J++, C#, and Java. These discussions are open to the public. On their websites, you may read some of these papers and do an analysis of how they affect delegates.
Write a C program which behaves as follows: If there are no command-line arguments at all when the program is run, the program should print out instructions on its use (a "usage message"). There should be one common usage message (consider a method/function for printing the usage message) for any type of usage error. The program will accept an A or D as the second command line argument (after the program name). This letter will tell you whether the bubble sort should sort in ascending or descending fashion. Anything other than A or D in that position should display the usage message and terminate the program. The program will be able to accept up to 32 numbers (integers) on the command line. If there are more than 32 numbers on the command line, or no numbers at all, the program should print out the usage message and exit with a non-zero value from main. This means 32 values not including the program name (argv[0]) and sort type. You may assume that the command line arguments (except…
