Chapter 8, Problem 8.22HW
Write your own version of the Unix system function
int mysystem(char *command);
The mysystem function executes command by invoking /bin/ sh -c command, and then returns after command has completed. If command exits normally (by calling the exit function or executing a return statement), then mysystem returns the command exit status. For example, if command terminates by calling exit (8), then mysystem returns the value 8. Otherwise, if command terminates abnormally, then mysystem returns the status returned by the shell.

Your task is to implement a variation of the classic word game Hangman, which involves playersguessing the letters in a word chosen at random with a finite number of guesses. While there arealternate versions such as category Hangman and Wheel of Fortune, which involve playersguessing idioms, places, names and so on, we will be sticking with the traditional version.
Requirements:You will implement a function called main that allows users to play an interactive hangman gameagainst the computer. The computer should pick a word, and players should then try to guess lettersin the word until they win or run out of guesses.Here is the overarching behaviour we expect:1. The program should load a list of available words from the text file provided. Note thatthe file you have been given contains words in lowercase.2. The computer should then select a word at random from the list at random.3. The user is given a certain number of guesses at the beginning.4. The game is interactive; the user…
The solution needs to be a script in C and follow the given requirements:
Only headers can be stdio.h and math.h; NO iostream or cacio or any of that;
Must utilize 3 or more UDF's;
Prompts user to enter the number of terms as well as the value of each term by utilizing array and loop;
Then prompts user to pick 1 out of 3 available functions they want to see; each of these should be done by making a udf that the user effectively selects.
1) Calculate and print the average, variance and standard deviation of the given set of values.
2) Sort the values Largest to smallest and calculate and print the median.
3)Display each value and whether it is less than or greater than the average.
Finally, it should prompt whether the user would like to run another one of the functions or end the program, and if prompted, be able to carry out one of the udfs again.
Thank you so much! Again, though, please only answer in C and using stdio and math headers only! Preferably stdio.h only.
The dirname utility treats its argument as a pathname and writes to standard output the path prefix—that is, everything up to but not including the last component:
$ dirname a/b/c/d
a/b/c
If you give dirname a simple filename (no / characters) as an argument, dir-name writes a . to standard output:
$ dirname simple
.
Implement dirname as a bash function. Make sure it behaves sensibly when given such arguments as /.

Given a specified number of degrees, the radians is equal to degrees * PI/180. Important: Be sure to declare PI to be 3.14159. This is so that mimir always comes up with the same answers no matter which server is used. 2) Drawline: takes in two parameters: a character and numRepetitions and prints the character numRepetitions times, followed by a newline. In your main function, for every 5 degrees between 0 and 360, calculate and print out the value of sin(toRadians(degree)) like so: GIVEN 45 DEGREES: sin(45) = 0.70711 To use the sin function, make sure to include cmath in your program. Be sure to set decimal precision to 5 places! Every 90 degrees (including 0 and 360), print out a line of 30 dashes ('-') using drawline after your print out the value of sin.

- Pleaser fix the code below: Since functions should do a single logical task, there is no need for the userInputCalc function to collect the info and also do the summary calculations, so move line 61 to line 72. Then, place line 67-72 inside a main() function, and place a call to this function at the end of the program file. Also, fix the names of the menu items (in menu_items) with spaces so they all have the same size. also, there is a simpler way: change {:<15} with {:<20} in lines 22 and 25. Also, use format for the “Subtotal” and “Grand total” (just like you did for “Sales tax” and “Suggested tip”) Also, the $ should go in front of the each amount. PLEASE MAKE THOSE CHANGES IN THE CODE BELOW: SummaryThis program will create a new version of the restaurant ordering programthat uses lists to look up menu items, record the items ordered by the user,and print a full receipt.''' def Menu(menu_items,menu_prices):print("Menu Card")count = 1for i,j in…arrow_forwardWrite a function that takes two lists of integers X and Y as input, and computes and writes a table into a file named "question2.txt" as follows: - On each line the computations for an X,Y pair is given - Each such possible pair must exist in the file in the same order of values in X and Y- Next on each line, you provide X+Y, X*Y and X^2 + Y^2, all separated by a comma (and no spaces or other characters must exist). Note that X^2 represents "square of X". For example, given X = [1,3] and Y=[-1,1,0], "question2.txt" should contain the following table: ----- question2.txt -----1,-1,0,-1,21,1,2,1,21,0,1,0,13,-1,2,-3,103,1,4,3,103,0,3,0,9------------------------- As you can see, the first line is computed for X=1, Y=-1. The second line is built for X=1, Y=1; and the third line is for X=1, Y=0. It goes on like this, until X=3, Y=0.arrow_forwardYour task is to implement a variation of the classic word game Hangman, which involves players guessing the letters in a word chosen at random with a finite number of guesses.

C++ requires use pointerarrow_forwardwrite a python code named get_total_cases() takes the a 2D-list (similar to database) and an integer x from this set {0, 1, 2} as input parameters. Here, 0 represents Case_Reported_Date, 1 represents Age_Group and 2 represents Client_Gender (these are the fields on the header row, the integer value represents the index of each of these fields on that row). This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary.
