The default library method int fseek(FILE *fp, long offset, int origin) is similar to Iseek except that the return value is an int status rather than a location, and fp is a file reference rather than a file descriptor. Compose fseek. Ensure that the caching used for the other library functions and your fseek are correctly coordinated.

The program contains a function for accessing the student file. The user wants to add some records to the file. Which of the following line of code is used to open the student file for implementing this functionality? Choose an answer A fp = fopen ("studentfile.dat", "r"); B ch = fgetc(fp); C fp = fopen ("studentfile.dat", "w"); D fputc (ch, fp);Which example uses the SOLID SRP principle correctly and does not violate it?

- sing good OOP, write a C++ program that will read an input file to manage a list of students waiting to register for a ourse using a linked list. The input file name is WaitList.txt and is located in the current directory of the project. The file layout is as follows: action student name Actions are defined as follows: 1 - add student name to the end of the linked list2 - add student name to the beginning of the linked list3 - delete the student at the beginning of the linked list4 - delete the student at the end of the linked list Actions #1 and #2 require student names. Actions #3 and #4 do not. For example, if the input file contents contained: 1 Sally Sue Student1 Peter Pupil1 Sam Scholar42 Terri Tutor1 Abby Achiever32 Bill Brain The program would display the wait list as follows: The Wait List: 1.
