Fread and fwrite in C Language

The C language provides the fread and fwrite File Read and Write Functions. If the file is opened in binary format, the fread and FW rite functions can be used to read and write any type of information. Fread is used to read data items from a specified file, while FW rite is used to write data items to the specified file. The formats are:
Fread (buffer, size, Count, FP );
Fwrite (buffer, size, Count, FP );
Buffer: a pointer. For fread, It is the storage address for reading data. For FW rite, It is the address for outputting data.
Size: the number of bytes to read and write.
Count: the number of size-byte data items to be read and written.
FP: file pointer.
Example: fread (sample1, sizeof (Bitmap), 1, FP );
