I think lz just wants to print out the address of a and the address of a+1 Here, a is the starting address of the array, so &a takes the address with a as a variable, that is, the address that stores the address of the array, but if (a+1) is addressed, it is not right, because (a+1) is not a defined variable here, but the value of a temporary variable, it is only equal to the value of the next address of the starting address of the array, not a variable that stores the value, and it is not right to take the address.
I don't know if I've made it clear
To add: if (a+1) is assigned to variable b first, i.e. int b=int(a+1); , it is possible to take the value of b again, i.e.
int b=int(a+1);
Cout "That's it!

It is an address, and A is already an address, so you can't address A or A+1.
To get the right result, you can't cout < first
There is also the main() function that must return the int value, which should be int main().
-
Cout "There is a big problem with the above sentence.
cout "The latter also wants to print the address, which doesn't make any sense.
The address of A is A, and it is the same with or without &.
There is no place to save (a+1) in memory, so &(a+1) is of course incorrect.
-
a[1] is the address of the second element, not a+1

1.Standard C++ requires that main have an int return value, and that int main() corresponds to return 0;Although the C++ standard does not allow main to be void, some compilers such as vc6 allow main to be void, and the header file is declared to include (in C++. H's header file is support for C, making it non-templated) It's better to learn C++ or write int main().
Many compilers ignore whether the main function is declared void or not. Earlier C functions were of type int by default, and did not detect whether undeclared functions returned data. In C++, in order to achieve consistency of description, all functions must declare types, and the custom of C is used for untyped declarations, but a return value is required for int types, otherwise a warning will be raised.
2.If the logic is correct, it shouldn't make a difference.
3.Encapsulation is all about hiding the details, and the customer just needs to know how to use it, regardless of how the function is implemented.
