Answer the question with C - language. Question. In the following code, assume that all function calls are successful. void sigusr1_handler(int sig) { } int main(void) { pid_t child; if ((child = fork()) == 0) { struct sigaction sa; sa.sa_handler = sigusr1_handler; sa.sa_flags = 0; sigemptyset(&sa.sa_mask); sigaction(SIGUSR1, &sa, NULL); while (1) { printf("working ...\n"); sleep(1); } } else { //line 19 sleep(30); } // line 22 return 0; } (a) If you run the above program can it create either an orphan or a zombie process? Explain how. (b) Insert statements in only the part of the code related to the parent process (Lines 19–22) and function siguse1_handler() so that the child process would end after about 30 seconds of running. Clearly indicate where you insert any statements. thank you for your time
A Person has a name (just a first name for simplicity) and friends. Store the names of the friends in a string, separated by spaces. Provide a constructor that constructs a person with a given name and no friends. Provide member functions. c++ void befriend(Person p) void unfriend(Person p) string get_friend_names()

In C++ implement the relational operators (<, <=, ==, !=, >, >=) in the Circle class in the code below, to order the Circle objects according to their radii. #ifndef CIRCLE_H#define CIRCLE_Hclass Circle{public:Circle();Circle(double);double getArea() const;double getRadius() const;void setRadius(double);static int getNumberOfObjects();private:double radius;static int numberOfObjects;};#endif
Overload the assignment operators (=) for Distance class. Your operator must be able to do multi-level assignments, e.g., statements like “d3 = d2 = d1;” must work as expected. A sample output is given below: Distance d1: 3'-9" Distance d2: 3'-6" After assigning d1 to d2 to d3 Distance d1: 3'-9" Distance d2: 3'-9" Distance d3: 3'-9" by using c++
IN C++, TRUE OR FALSE : Every if statement must have a corresponding else. C does not provide for the use of classes. The expression !(x > 0) is true only if x is a negative number. C and C++ were both invented in the 1960s. When a return statement executes inside a function, the function immediately exits. A function that changes the value of a variable passed by value also changes the value of the original variable. Both local variables and parameters to a function are stored in memory on the heap.
In c++, write a function Circle::intersect(Circle c) where class is defined below, for the funtion it returns bool values, true if two circle outline intersect each other and false if not. Circle::intersect(Circle c) { // example double X = x - c.getX(); double Y = y - c.getY(); double rad = radius + c.getRadius(); } class Circle { private: double x; double y; double radius; public: bool intersect(Circle c); }
