STL之使用vector排序

应用场景：

　　在内存中维持一个有序的vector：

root@u18:~/cp/test# valgrind --tool=memcheck --leak-check=yes ./a.out

==24247== Memcheck, a memory error detector

==24247== Copyright (C) 2002-2011, and GNU GPL'd, by Julian Seward et al.

==24247== Using Valgrind-3.7.0 and LibVEX; rerun with -h for copyright info

==24247== Command: ./a.out

==24247==

Before Sort:

0 sh

1 shsh

2 shshsh

3 shshshsh

4 shshshshsh

5 shshshshshsh

6 shshshshshshsh

7 shshshshshshshsh

8 shshshshshshshshsh

9 shshshshshshshshshsh

对向量中的所有元素按member1进行升序排列:

==24247== HEAP SUMMARY:

==24247== in use at exit: 0 bytes in 0 blocks

==24247== total heap usage: 25 allocs, 25 frees, 768 bytes allocated

==24247== All heap blocks were freed -- no leaks are possible

==24247== For counts of detected and suppressed errors, rerun with: -v

==24247== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 2 from 2)
