In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:
- Separate big codebases into multiple repositories.
#include <time.h> | |
#include <stdint.h> | |
#include <sys/types.h> | |
#include <stdio.h> | |
#include <ctype.h> | |
/* | |
Character-by-character comparisons for equality and lowercasing. | |
Custom functions vs tolower. | |
Spoiler: lookup table is the fastest. |
