#Natural sort in C++ This includes a natural sort algorithm that sorts strings in a human perceivable way. This algorithm was originally written by Martin Pool http://sourcefrog.net.

#Files:

1. strnatcmp.hpp : the only header file which includes all the required functions.
2. test.cpp : a test cpp file to test the algorithm.

#Result of a test:

sort with ignore case:

Before	After
20.txt	1.txt
10.txt	1_t.txt
1.txt	10.txt
z2.txt	20.txt
z10.txt	aaa
z100.txt	aaA
1_t.txt	ABc
ABc	aBc
aBCd	aBCd
aBc	aBcd
aaa	z2.txt
aBcd	z10.txt
aaA	z100.txt
