Reading and Writing in a Binary File
A Binary file is similar to the text file, but it contains only large numerical
data. The Opening modes are mentioned in the table for opening modes

fread() and fwrite() functions are used to read and write is a binary file.
above.

fwrite(data-element-to-be-
written,
size_of_elements
number_of_elem
ents, pointer-tofile);

fread() is also used in the same way, with the same arguments like fwrite()
function. Below mentioned is a simple example of writing into a binary file
const char *mytext = "The quick brown

fox jumps over the lazy dog"; FILE *bfp=

fopen("test.txt", "wb");

if (bfp) {

fwrite(mytext,
sizeof(char),
strlen(mytext), bfp) ;
fclose(bfp) ;
