The source code comes from a console application project created
in and may require slight adjustments to work in the compiler
especially the declarations of functions. You should know that
the compiler is set up to use so local variables must be
declared at the beginning of the function. Read file from
language using #include file character buffer read from file in
if! size else file not found. Has the following function
definition The first parameter it accepts is a pointer to the
memory area that will hold the data read from the file. In this
example the code specifies a character array as the target.
The parameters define the size of the individual elements being
read. The data type is single byte so the value used here is .
Specifies how many elements to read from the Phone Number List

file specify size. The value can read
up to characters from the file. Finally the stream parameter
specifies the file stream to read from usually the pointer
returned by the call. Programming Language Students also learn
There are a few other points to note in the above code. Check
that the return value of is to ensure that the file was opened
successfully.

The code does not check whether the call to was successful and
returned the requested number of characters. Before sending the
results to the console using the last element in the buffer
array is set to to ensure that the string is terminated with .
If the file contains fewer bytes than requested the call reads
as many values as possible and returns a value indicating how
many values were read. a buffer array of characters and then
displays how many characters were actually read from the file
stream. Read file from language using #includes file character
buffer internal resource read from file in if ! reads bytes.
Other File not found.
