QUESTION 6 To determine whether a file was opened successfully, the program can use the fstream function: Hint: google fail() open() close() eof() 10 points QUESTION 7 Which of the following are correct ways to end a loop using a test for end-of-file? (Two correct answers) inStream.get(next); while(!inStream.eof( )) { cout << next; inStream.get(next); } while(inStream->next) { cout << next; } inStream.get(next) while(!eof(inStream)) { cout << next; inStream.get(next); } while(inStream >> next) cout << next; 10 points QUESTION...
Operating systems in C 15.) Suppose a program has successfully opened a file object, fp, for reading a file from a disk drive and the program has created a buffer, my-but, of an appropriate size. Consider the following C function call. fread (my_buf, 1, BUFFERSIZE, fp); a) Explain why this function call may, or may not, cause a system call to the operating system. b) Suppose that the above function call causes a system call. Explain why the operating system...
One of the critical responsibilities of the operating system is to manage the file system. When discussing the file system, the operating system has several tasks that it can perform. Listed below are 6 tasks that can be performed on files by the operating system. Describe in a sentence or two how the operating system handles each task. CREATE WRITE MOVE REPLACE CLOSE DELETE
Question 5. ArcGIS records projection and coordinate system information into a file with prj extension. Open MD_cities_SPCS.prj in any text editor (e.g., WordPad, Notepad, etc.). Read the prj file, and explain the following information for the MD_cities_SPCS layer: projection, geodesy, GCS, geodetic datum and unit. Make sure you do not change the file (i.e., do not save the changes if you ever modify the content of this file. You may read ArcGIS Help to answer this question. (2 points) this...

File structure is a structure, which is according to a required format that operating system can understand. A file has a certain defined structure according to its type. A text file is a sequence of characters organized into lines. A source file is a sequence of procedures and functions. An object file is a sequence of bytes organized into blocks that are understandable by the machine. When operating system defines different file structures, it also contains the code to support...
