The sum of the diagonal of the 3*3 matrix is mainly about the representation of the diagonal elements: on the main diagonal, all the elements are equal, in the form of a a[i][i] format. On the diagonal, the sum of the upper and lower bounds of all elements equals 2, i.e. a[i][j],i+j=2. The format code is as follows: #include So it's easy to find the sum of the diagonal

3. Process Regular Expressions Let's talk about using the ereg () and eregi () functions to process regular expressions. As I mentioned earlier, some of these functions are simple and complex, depending on your actual needs. With regular expressions, you can check a string, search for some schema patterns, and determine whether these patterns meet your requirements. The most common usage includes checking whether the email address is valid (of course

ASP. net e-commerce system development-3 (orders), asp.net-3I. Preface This is the third article after the last shopping cart. Record the order function. When this function was implemented, it was a detour, and it was very brainless. Because the idea was not straightened out, the database design was not very good, and only half of it found the problem, and then the database was re-designed, after clarifying our ideas, we finally finished it.Ii.
