Compose fseek. Ensure that the caching used for the other library functions and your fseek are correctly coordinated.
- in C# Look at Figures 9-35 and 9-36 on page 392 of your book. There should be two blocks of code: A Book class and an AddBooks program. In your IDE, create a new .cs file called books.cs, then type this code (you can type both parts in books.cs), then compile it and run it. NOTE: There IS an error with the codeSelect the statement that is false regarding file guarding. Group of answer choices: In your .h files all code should be contained within the guards.
