changed, the programmer can only create a larger new array and then copy all the elements of the original array into the storage space of the new array. Programs that use built-in arrays are more error-prone and difficult to debug than programs that use the vector type.Question 6, attention to the array subscript cross-border problemSimilar to vector container, string type, no other method, certain self-study inspection. A common "buffer overflow error" is when writing code, referencing the sub

Although the trailing pointers can be computed, this usage is extremely error-prone. To make the use of pointers easier and more secure, the new C + + standard introduces two functions called Begin and end. These two functions are similar to the two members of the same name in the container, although the array is not a class type after all, so these two functions are not member functions. The correct form of use is to have arrays as their parameters:int a[] = {0,1,2,3,4,5,6,7,8,9};int *beg = Beg

it will be an error ( you can try it yourself to see what the situation is ).18. Assignment operators achieve copy assignment and move assignment two functions P478If the parameter of the assignment operator is a call to a value , the initial taxiing parameter with the argument needs to call the copy constructor ( The argument is an lvalue ) or move the constructor ( the argument is the right value ). Then the equivalent copy assignment and move assignment can be implemented in the following wa

5th Chapter Statement1. The case label in switch must be an integer constant expression and cannot be a variable or a non-integral type:Note that the second case 3.14 does not have an error in c++11, but the compilation does not pass in c++98.2. Note that the case statement of the switch statement initializes a variable:A case statement cannot skip initialization of a variable, and you can skip the definition of the variable.3. The scope for statement can not only declare variables with auto:for
