3. (5 points) describe what would be printed by the code below or what error would occur. const char* cstr = "0123456"; const char* ptr = & cstr[4]; cout < < ptr[-1] < < ptr < < endl; 1 4. (5 points) theseus has been trapped in a maze with a minotaur, which is trying to capture him. each round, theseus and the minotaur move through the maze; theseus towards the exit, and the minotaur towards theseus. theseus can move in any of the four cardinal directions, or he can wait for a round to see how the minotaur moves. write code that creates a data type to represent the possible moves that theseus could make.

1. the program must provide following functions to extract some statistics. note that the data_list parameter specified in these functions may be the same for all functions or different for different functions—that is your choice. a skeleton file is provided on mirmir. a) open_file()prompts the user to enter a year number for the data file. the program will check whether the year is between 1990 and 2015 (both inclusive). if year number is valid, the program will try to open data file with file name ‘year.txt’, where is the year. appropriate error message should be shown if the data file cannot be opened or if the year number is invalid. this function will loop until it receives proper input and successfully opens the file. it returns a file pointer and year. i. hint: use string concatenation to construct the file name b) read_file(fp)has one parameter, a file pointer read. this function returns a list of your choosing containing data you need for other parts of this project. c) find_average(data_list) takes a list of data (of some organization of your choosing) and returns the average salary. the function does not print anything. hints: i. this is not the average of the last column of data. it is not mathematically valid to find an average by finding the average of averages—for example, in this case there are many more in the lowest category than in the highest category. ii. how many wage earners are considered in finding the average (denominator)

Consider the following statements, then select one of the answers below: the signal() function shown below registers "sig_handler()" as the signal handler function for the sigkill signal, without the complexity of using when the sigkill signal is sent to a process running this code, by a user typing "kill -kill ", where the correct process id is used for to target the process, sig_handler() will be executed.
