Because the space is very short, try writing it all. It's not necessary to finish the text in a few minutes or more than 10 minutes.The Foreach Traversal list operation is convenient, saving some [] code for data and subscript calculations. It's simple to write. However, if you are traversing delete, you will encounter a classic iterator invalidation problem.A common idea to solve this problem is to put a temporary container B on the element that needs to be removed in container a. Then traverse
See a topic saying that a pointer and an array are defined consecutively in the stack, similar to this{Char *ptr = points to an array of characters;Char Buf[8];Gets (BUF);strncpy (ptr,buf,8);}When modifying the BUF array, an out-of-bounds modification of the PTR pointer points to a problem that is designed to be robust to the program.When I tried this piece of code with VS2013, something weird happened and I typed more than 8 characters, but the point of PTR didn't change.So I tried this code.#i
