1. Write append program. This program must be able to accept two arguments which are as destination and source files. Then, the content of the source file must be appended to the destination file. The program must also accept --help argument, in which case, would show some help instructions regarding its functionalities and synopsis. In case destination file does not exist, it must be created. In case source file does not exist. the program should indicate and print an error message accordingly and exit. In case no argument is given, the program should indicate the error. Use of perror will assist with the error message. Create a makefile to automate the compilation and cleaning of the directory objects. There is an example makefile in the lab folder. The order of arguments to be fed into the program is as follows: ./append destination source ./append --help You can use the source codes that are available on Canvas. Upload the source code (.c file) and Makefile to Canvas. Note: Source file name must be one file, named append. c Note: The program must be compiled with no error.
