Files and File System Exercise

Practice the materials from this topic by implementing the projects presented below.

File Manipulator

Write a program file-manipulator.c that requires 3 arguments: words_count, min_length, max_length. The program should generate a file called file-manipulator.log that contains words_count number of words (separated by spaces). To generate the words, create a function random_word_generator (the function will not generate real words, but rather random sequences of characters):

char* random_word_generator(int min_length, int max_length);

Then the program should print the generated file to the screen.

After the program creates the file file-manipulator.log and before writing to it, it should lock the first 100 bytes of the file. When the program prints the generated words, it should wait for the Enter key to be pressed, then unlock the file. Accordingly, if the file is already locked by another process, the program should notify about this and wait for the Enter key to be pressed before trying again (to lock, generate, and write).

Compile and run several times for testing.
