structure of node in the linked list has been declared in "lab3.h". Also, the functions of linked list have been declared in "lab3.h" as well. In "main.c", these functions are called. Your work is to finish these function implementations in a separate C source file, and create a makefile which can compile your separate C source file along with "main.c" and "lab3.h". You can follow the comments in "main.c" and "lab3.h" to finish this lab. Please do not change "main.c" and "lab3.h", because your separate C source file will be compiled with these two files posted on BlackBoard. When you test your program, please put "main.c", "lab3.h", your separate C source file and your makefile in the same directory and compile.

//create a makefile to compile the code using VIM terminal (Hint: gcc, -o, ./, etc.)
