The program shown in Figure 4.22 uses the Pthreads API. What would be the output from the program at LINE C and LINE P? #include #include int value - 0; void *runner(void *param); /* the thread */ int main(int argc, char *argv []) { pid_t pid; pthread_t tid; pthread attr_t attr; pid - fork(); if (pid -- 0) { /* child process */ pthread attr_init(&attr); pthread_create (&tid,&attr,runner,NULL); pthread_join(tid,NULL); printf("CHILD: value = %d",value); /* LINE C */ else if (pid > 0) { /* parent process */ wait(NÜLL); printf("PARENT: value = %d",value); /* LINE P */ } void runner (void *param) { value - 5; pthread exit (0); } Figure 4.22 C program for Exercise 4.19.

PP 13.3 Create a new version of the LinkedStack class that makes use of a dummy record at the head of the list. PP 13.4 Create a simple graphical application that will allow a user to perform push, pop, and peek operations on a stack, and display the resulting stack (using toString) in a text area.

Complete the following code. The goal is to implement the producer-consumer problem. You are expected to extend the provided C code to synchronize the thread operations consumer() and producer() such that an underflow and overflow of the queue is prevented. You are not allowed to change the code for implementing the queue operations, that is the code between lines 25 and 126 as shown in the Figure below. You must complete the missing parts between lines 226-261 as shown in the screenshot.

OCaml Code: The goal of this project is to understand and build an interpreter for a small, OCaml-like, stackbased bytecode language. Make sure that the code compiles correctly and provide the code with the screenshot of the output. Make sure to have the following methods below: -Push integers, strings, and names on the stack -Push booleans -Pushing an error literal or unit literal will push :error: or :unit:onto the stack, respectively -Command pop removes the top value from the stack -The command add refers to integer addition. Since this is a binary operator, it consumes the toptwo values in the stack, calculates the sum and pushes the result back to the stack - Command sub refers to integer subtraction -Command mul refers to integer multiplication -Command div refers to integer division -Command rem refers to the remainder of integer division -Command neg is to calculate the negation of an integer -Command swap interchanges the top two elements in the stack, meaning that the...

Write a program that takes as input an arithmetic expression. The program outputs whether the expression contains matching grouping symbols (brackets and parentheses). For example, the arithmetic expressions {25 + (3 – 6) * 8} and 7 + 8 * 2 contains matching grouping symbols. However, the expression 5 + {(13 + 7) / 8 - 2 * 9 does not contain matching grouping symbols. You must use a stack and/or queue. USE THE FOLLOWING DATA FILE //Header file: stackADT.h #ifndef H_StackADT#define H_StackADT template <class Type>class stackADT{public:virtual void initializeStack() = 0;//Method to initialize the stack to an empty state.//Postcondition: Stack is emptyvirtual bool isEmptyStack() const = 0;//Function to determine whether the stack is empty.//Postcondition: Returns true if the stack is empty,// otherwise returns false.virtual bool isFullStack() const = 0;//Function to determine whether the stack is full.//Postcondition: Returns true if the stack is full,// otherwise returns...

Computer Science For the basic ADT Queue operations, list all cases when a QueueException will be thrown. Each item listed should be no more than 10 words and ONLY in the form "exception name : cause of exception". Remember to use correct terminology or the answer will not be accepted
