To open all files in tabs as one command:
$ vim -p test_print_integer.c print_integer.c print_integer.h
Don't type the leading $. It is just a reminder that this is something you type in bash.
$ vim -p *.?
*.? means a file that consists of 0 or more characters (*), a period (.), and one more
character (?). This includes print_integer.c test_print_integer.c print_integer.h, but does
not include test_print_integer (the executable) or something like readme.txt (ends in 3
characters).
Angle brackets are for system header files that come with Linux or your compiler.
#include <stdlib.h>
Double quotes are for header files that you provide.
#include "print_integer.h"
:w saves only the current file.
:wall saves all open file.
:x is the same as :w and then :q
:xall is the same as :wall and then :q
OPTIONAL
$ ./test_print_integer > actual.txt; diff actual.txt expected.txt
$ diff <(./test_print_integer) expected.txt
To see man file for fputc (or other standard library functions, put cursor
over the function name in normal mode and then press K (capital letter).
To exit the man file, press q.
