9.6.2 Unformatted File I/O Operations

An opened file can be read or written by the following set of unformatted I/O functions:

fget(), get(), fgetchar()

getw(), fputc(), putc()

fputchar(), fputs(), putw()

A brief description of each function has already been provided in Table 9.2.

Let us consider a situation wherein we desire to create a file called “message.dat” containing the

following text:

“When one apple fell, Newton was disturbed;

but when he found that all apples fell;

it was gravitation and he was satisfied”.

The file “message.dat” would be opened with the help of fopen() function and the function

fputs()
