is short, the third is char, and then combined to get the integer data. If the variable is in the natural alignment position, the data can be fetched once. Some systems have strict alignment requirements, such as SPARC systems, where an error occurs if an unaligned data is taken, as an example:Char Ch[8];Char *p = ch[1];int i = * (int *) p;The runtime will report segment error, and there will be no errors on the x86, just a decrease in efficiency.3.

5. Neglected post submitted information
Many people strictly filter the tools conveyed on the url. It is a fault to ignore the tools used to deal with post. The tools used for post are especially double and simple to be injected, because the common fields have a lot of corner power.
In asp.net, we strongly recommend parameter determination to implement SQL rather than SQL concatenation, because even if you filter hundreds of passwords

It is not correct to ignore post content. post content is easier to be injected because there are many fields.In asp.net, we strongly recommend that you use parameters to implement SQL statements instead of SQL concatenation, because even if you filter hundreds of passwordsFor example:SqlConnection conn = new SqlConnection (System.

Now there are two tables to insert data in Table A into Table B. They all have three fields, and the fields in Table A do not have a primary key, and there are also repeated data fields, however, this field in Table B does not need to be repeated and must be unique. At this time, I thought of a simple and fast way to use the cursor to read data from one row and one row, insert the read data into a temporary table. In the temporary table, I set a self-increasing ID so that the duplicate can be el
