Questions & Answers

Q: How many types of files can be handled in file handling operations?

File handling operations can handle three types of files: sequential, random access, and binary files.

Q: What is the purpose of the F open function in file handling?

The F open function is used to open a file and establish communication with it before performing any operations.

Q: How do we read a character from a file?

To read a character from a file, we use the get C function, which reads a character into a character variable.

Q: What is the purpose of the F gates function?

The F gates function is used to read a string from a file, and the syntax for using it is F gates (string length, file pointer).
