Console program for viewing BMP files

1.DEV 5.0

Program usage DEV 5.0 Development . But because the author's operating system is Chinese , So use printf Print more than ASCII code 128 I will appear Chinese garbled code . This is because two are greater than 128 Of ASCII Of WINDOWS In the Chinese system, it is changed to by default GB2312 Chinese characters of . The solution is , Open console , Turn the current environment into English .

-----------------------------------------------------------------------------
Console command |Windows Console code page code | meaning    |
-----------------------------------------------------------------------------
chcp              |437                                          | American English |
------------------------------------------------------------------------------
chcp              |936                                          | chinese GBK |
-------------------------------------------------------------------------------

chcp The order is ： chcp code page .

2.WIN TC

Later, the operating system was reinstalled , stay 64M Move U Found it on the disk WINTC This compiler . compile 、 Run it ,OK. No need to change the code page .
