Description
1. Execute and familiarize with Linux environment and commands
- Getting used to basic commands on Linux Operating System – Process creation, Process monitoring, Process states, Linux File system tree, Linux File system commands
- Write a C program to display an array in reverse using index.
Create Makefile (ex: make.mk below) and other files as shown below: (Hint: Refer to Makefile tutorial sent before to create these files)
Client.c – contains main function to collect input on array elements from the user and calls reverse_array function
Server.c – contains reverse_array function and prints the reversed array (use a separate function to print the reversed array)
Header.h – contains function prototypes
make.mk – contains targets and their dependencies
Program Execution and Expected Output
$make -f make.mk
$./a.out
ENTER SIZE OF AN ARRAY
4
ENTER ELEMENTS OF AN ARRAY
1
2
3
4
Input array is
1234
Reversed array is
4321
Submission
- Basic LINUX commands (ANY 5) executed in the lab should be submitted in the following way:
Command: What does the command do?
Any two options (i.e flags or arguments) regarding the command
Outcome of the command
- Main program and all sub programs (dependency files, header file and Makefile) should be submitted. Steps to execute make and output of the program should be submitted.
- Answer the following questions (Brief answers only)
-
Why do we use Makefile?
-
Is Makefile a shell script?
-
What does “clean” do in Makefile?
-
How does make learn about the last modified files to be complied?
-
What does Cflags in Makefile mean?
-
Why do we use -f option with make command?
