FILE HANDLING IN C PROGRAMMING - IDC-Online
The type FILEdefined in stdio h allows us to define a file pointer Then you use the function fopen()for opening a file Once this is done one can read or write to the file using the fread()or fwrite()functions respectively The fclose() function is used to explicitly close any opened file

What is fwrite function in C++?
- The fwrite() function in C++ writes a specified number of characters to the given output stream. fwrite() prototype size_t fwrite(const void * buffer, size_t size, size_t count, FILE * stream);
How to use fread and fwrite functions?
- fread () and fwrite () functions are commonly used to read and write binary data to and from the file respectively. Although we can also use them with text mode too. Let's start with fwrite () function. Syntax: size_t fwrite (const void *ptr, size_t size, size_t n, FILE *fp);
How to check the return value of fwrite ()?
- Return value of fwrite () may be checked: On systems which differentiate between binary and text files (i.e. Windows) the file must be opened with 'b' included in fopen () mode parameter.
