# Type "gcc --version" into the terminal. If the command is not found, it is likely that GCC isn't installed.
# Go to the directory where your .c program files are located.
# To compile a single source file, type: gcc -o outputfile file1.c
# To compile multiple files, type: gcc -o outputfile file1.c file2.c file3.c
# To compile with more error checking using the -Wall tag: gcc -Wall -o outputfile file1.c
# To compile files without linking them type: gcc -c file1.c file2.c file3.c
# After the last step, if you want to link them, type: gcc -o outputfile file1.o file2.o file3.o
# Fix any errors/warnings the compiler reports.
# Recompile the code if you had to fix errors.

----- compile files without linking

----- more error checking using the -Wall tag
gcc -Wall -o outputfile file1.c

----- compile files with linking
