c# - How to identify the binary compression type from the content? -


i trying restore files stored in ms sql database (used third party application has stopped support) image data type(byte arrays). write rows of byte arrays file convert know file extensions. of them not known believe compressed. since "cc_compress" string , random characters in file after conversion. wondering if possible find out compression method used , how can decompress before convert them.

following first bytes byte array: 0x43435f434f4d50524553530000000000000000000000010004f60000e4780000ec7c075c54c7f3f85ca10a8a204544796001519a0d4569414414011115238a079c80c21d5204224d632c51c19268628fc6a851638b9a88882d9604c5d83bb688a002564085fbcfbebdc71dcd16623effef2fa373b33b5b667676b6bc7dcb3b9ddff2e677db8d6f411d70060154cb34401514c043d4e5223a00ad80f2aa65321961b54494fd07ff5fc1c3750741304e430850a19b0b2ce8b0bfd8f16dd5019a43c88490097fc4fd1107f5404368003d740036b6e6b1d816de0c32598bb78639f89efddd20801aaa1c6e8cb60205e

and 43435f434f4d5052455353 part converts cc_compress

thanks in advance,

raw deflate-compressed data begins 32 bytes in (starting ec 7c). can use zlib decompress it.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
