What is file handling explain with example?
File Handling is the storing of data in a file using a program. In C programming language, the programs store results, and other data of the program to a file using file handling in C. Also, we can extract/fetch data from a file to work with it in the program. The operations that you can perform on a File in C are −

Why do we need file handling?
File handling provides a mechanism to store the output of a program in a file and to perform various operations on it. A stream is an abstraction that represents a device on which operations of input and output are performed. fstream: This Stream class can be used for both read and write from/to files.
What are file functions?
A file is simply a resource for storing information on a computer. Files are usually used to store information such as: Configuration settings of a program. Simple data such as contact names against the phone numbers.
What is the advantage of file handling?
Large storage capacity: Using files, you need not worry about the problem of storing data in bulk. Saves time: There are certain programs that require a lot of input from the user. You can easily access any part of the code with the help of certain commands.
What is file handling and what is the need of it?
File handling in C++ is a mechanism to store the output of a program in a file and help perform various operations on it. Files help store these data permanently on a storage device. File Handling is a hot topic when it comes to storing such programming data.
What is function prototype in C with example?
A function prototype is a function declaration that specifies the data types of its arguments in the parameter list. Functions can be declared implicitly by their appearance in a call. Arguments to functions undergo the default conversions before the call. The number and type of arguments are not checked.
