QUESTION 2 - Pointers in C Write a short C program that declares and initializes (to any value you like) a double, an int, and a char. Next declare and initialize a pointer to each of the three variables. Your program should then print the address of, and value stored in, and the memory size (in bytes) of each of the six variables. Use the "%p" formatting specifier to print addresses in hexadecimal. You should see addresses that look something like this: "Oxbfe55918". The initial characters "Ox" tell you that hexadecimal notation is being used; the remainder of the digits give the address itself. Use proper formatting specifiers for char, int and double. Use the sizeof operator to determine the memory size allocated for each variable. Sample output from your program: The address of char The address of int The address of double The address of char* is Ox is Ox is Ox is Ox

Please solve the following in Java Sean can't remember where he put an important file on his computer. He desperately needs the file tonight to finish his homework, since he procrastinated all day by playing computer games. Unfortunately, his computer has gotten fried from all the gaming, and can no longer perform automatic searches for files. He therefore has to look for the file manually.Since he tends not to use subdirectories too much,he knows his best bet is to look for the file first in the root directory ("/"), and next in directories only one level deep (for example, "/Games/"), and so forth, checking the "deepest" directories last. His computer still has enough fire power to run some simple programs, so he has asked you to code for him a simple algorithm to sort all of the directories on his computer. ThealgorithmshouldtakeaString[]dirsasaninputand should sort dirs first by directory depth, and then lexicographically for each depth. So "/d/e/" comes before "/a/b/c/", but not…

************** The code provided to me when I asked this question is my own code from a preious question I asked on how to make it faster. My code is too slow and times out. I am looking for guidance on how to make it faster or a suggestion for a different approach. The question and my code are below. ************** Question Colour trio def colour_trio(colours): This problem was inspired by the fun little Mathologer video “Secret of Row 10” whose fractal animation once again remind us about how moving from two to three often opens the barn door for the chaos horse to emerge and wildly gallop away. To start, look at three values imaginatively named “red”, “yellow” and “blue”. These names serve as colourful (heh) mnemonics that could just as well have been “foo”, “bar” and “baz”, so no connection to actual physical colours is intended or implied. Next, de0ine a simple mixing rule between these colours with a rule that says that whenever any colour is mixed with itself, the result…

Course Title: English Language Asst. Lect. Ali Kareem Naser ****** ******** Reading Read the passages and decide if the following statements are TRUE or FALSE. (A) I am an art student and I painted a lot of pictures. Many people pretend that they understand modern art. They always tell you what a picture is about. Of course, many pictures are not about anything. They are just pretty patterns. I think that young children often understand modem pictures better than anyone else. My sister is only seven but she always tells me whether my pictures are good or not. She came to my room yesterday. She looked at it carefully for a moment. "t's alright", she said, "but isn't it upside-down?" I looked at it again. She was right! 1-Young children often understand modern pictures better than anyone else. 2-The writer is a teacher. 3-The writer's sister is twelve years old. 4 His sister always tells him whether his pictures are good or not. 5-She came to his room last week. 6-Many pictures are not…
