Why is there a paragraph error here? Very simple, because we want to copy 256 bytes of ' A ' to 16 byte size buffer, so there is coverage, from the above image can be seen SFP, ret, *str are covered as ' a ', and ' a ' ASIC code is 0x41, So ret is 0x41414141, this address exceeds the program's address range, so is illegal access, there will be a segment error. So a buffer overflow allows us to modify the return address o

, should you create and use indexes? But under what circumstances do indexes need to be created? IN general, you need to create an index for the columns that appear IN the WHERE and JOIN operations, but this is not the case because MySQL only applies to
SELECT t. vc_Name FROM testIndex t left join myIndex m ONt. vc_Name = m. vc_Name WHERE m. I _Age = 20 AND m. when vc_City = 'zhengzhou ', you need to create an index for the vc_City and I _Age OF THE
establishment
Vc_Name, vc_City, I _AgeVc_Name, vc_CityVc_Name
These three composite indexes! Why are there no composite indexes such as vc_City and I _Age? This is because mysql Composite Index "leftmost prefix" results. A simple understanding is to combine only from the leftmost. Not as long as the query contains these three columns will use the composite index, the following T-SQL will use:
SELECT * FROM myIndex WHREE vc_Name = "erquan" ANDvc_City = "Zhengzhou"SELECT * FROM myIndex WHREEvc_Na
