1. Reading and Writing to Text Files
Create a function access_file(filename) that copies the contents of the file filename and appends the data to the file ‘file_logs.txt’.
2. Loading, Manipulating, and Saving Images
Create a function manipulate_image(filename) that opens the image filename, prints the RGB values of each pixel, and saves the image with the blue component of all pixels halved. The image must have the original filename prepended by ‘filtered_’. Assume that all images will be in the RGB encoding.

File access type supported by most modern operating systems are said to be
a.
Sequential access files
b.
Random access files
c.
Structural access files
d.
Direct access files
The standard library function int fseek(FILE *fp, long offset, int origin) is identical to Iseek except that fp is a file pointer instead of a file descriptor and the return value is an int status, not a position. Write fseek. Make sure that your fseek coordinates properly with the buffering done for the other functions of the library.
