Notes about delete:After the delete operation, we recommend that you reset the pointer value. For example:Delete P;After the execution, p becomes undefined. On many machines, although P is meaningless, it still stores the address of the object it

Today, I have nothing to worry about. I will write the code for fast sorting and binary search, and I will review it for myself. The following code is successfully tested by vc2005. // The most important function for dividing interval FunctionsInt

1. c ++ is a strongly typed language. Generally, the compiler checks out unsuitable transformation operations. 2. type conversion format: Old-style transformation (the two methods are essentially the same ): C style: (t) expression.

Not long ago, I published an article on my blog-10 simple methods to improve the efficiency of running the program. Many readers raised questions to me about the last point of this article, which is to be used for direct initialization, I also wrote
