First, a piece of code:#include #include char* test (void) {char arr[] = "hello,world\n";//arr[] All elements are stored on stack memory, arr is a symbolic address, no storage space return arr;//warning C4172: Returns the address of a local

Vector in C + + is a very flexible array, it can automatically expand the size to accommodate the new elements, but also can quickly index the stored elements, however, this use of convenience is also a cost, because the vector's underlying data

　　A const-defined constant is freed after its scope has been exceeded, and static constants defined by Statics do not release their storage space after the function executes.Static is expressed statically. Static member functions and static member
