- File system implementation: a. Given a flename in a directory’s data block, how does OS locate the data block of a fle? b. Compare between direct pointers and indirect pointers in referencing data blocks. c. Given a 6GB fle, identify the number of index level needed when using indirect pointer.Function 1 load_treasure_map(filename): Takes a string as input corresponding to a filename. Opens the treasure map at that filename and loads the treasure map into a list of lists, then returns said list of lists. You can assume that the file will exist. Note that the treasure map could have any number of rows and columns. If there is any issue with the format of the file (e.g., it is not a matrix, or contains any invalid characters), then raise an AssertionError with an appropriate error message. Note that an 'X' in a file is valid. Note: In the example below, we show each row of the resulting list on its own line, but when you use doctest, you must put all the rows of the list into one line of code, as doctest checks for any improper whitespace Function 2 write_treasure_map(treasure_map, filename): Takes as inputs a list of lists corresponding to a treasure map and a string corresponding to a filename. Writes the treasure map to a file at the given filename, with a newline after…AHPA #11: Changing Grades *use c programming language * Create a C function (switcher) that will receive a pointer to the finalExams array, using only pointers look for D scores and boost them to C scores.

- Character arrays and pointers in C: I have to search and sort through an EXTREMELY large text file in C using standard libraries. How do I import the text file and then access any character in the file using pointers? I need to be able to access multiple different characters at different positions in the file at once, so using the fgetc() function doesn't help as I can only access 1 character at a time in that order that it is read. The text file is way too big to create an empty char array and store each character and access them that way, so I'm not sure what else I can do.

Make the code in the link as your basis: https://drive.google.com/file/d/1bKmRLh8hO2lcNHRbomOpK3YnComWZGrd/view?usp=drivesdkPointers A pointer is basically a reference to an object or a function. In fact, it is a variable that holds memory address. This address is the location of some other variable or object in memory. For example, if one variable contains the address of another variable, first one is said to point to the second one. Pointers may have many uses, such as to make functions implement “call-by-reference” methodology and to construct dynamic arrays or structures at run-time. a) Write a complete C program that demonstrates the usage of call-by-reference technique needed for swapping. Develop a call-by-value version to see that changes done to the parameters inside the function are lost. b) Write a complete C program that implements below given user-defined function prototypes for arrays-of-integers. void input_1d_array( int*, int ); void output_1d_array( int*, int ); int sum_1d_array( int*, int ); float average_1d_array( int*, int ); Test each function separately! c) [if time allows]…
