Consider the c program given below (on the next page). assume that all fork() and wait() calls complete successfully. answer the following questions: - (2 points) how many processes are created during the execution of this program (including the "parent" process)? - (2 points) draw the process hierarchy tree for this program. - (3 points) in which order did the processes in the hierarchy tree start and complete? why? explain your answer. - (3 points) which processes (among those in the hierarchy tree) will execute the line marked by "do computation". explain your answer. code for question 19: #include #include #include #include int main(void) { pid_t pid, pid2, pid3; int status, status2, status3; pid = fork(); if (pid == 0) {

Consider the following declarations (1, 2, 3, 5, 7)class bagtype{public: void set(string, double, double, double, double); void print() const; string getstyle() const; double getprice() const; void get(double, double, double, double); bagtype(); bagtype(string, double, double, double, double); private: string style: double l; double w; double h; double price; }; a.) write the definition of the number function set so that private members are set according to the parametersb.) write the definition of the member function print that prints the values of the data membersc.) write the definition of the default constructor of the class bagtype so that the private member variables are initialized to "", 0.0, 0.0, 0.0, 0.0, respectively d.) write a c++ statement that prints the value of the object newbag.e.) write a c++ statement that declares the object tempbag of type bagtype, and initialize the member variables of tempbag to "backpack", 15, 8, 20 and 49.99, respectively
