Example text

The variable returned should never be a local variable, since the memory to these variables is released when the function ends. Instead, return by reference is commonly used to return an argument that has also been passed to the function by reference. int& byRef(int& i) { return i; } int main() { int a = 10; cout << byRef(a); // 10 } 41 Chapter 11 ■ Functions To return by address the dereference operator is appended to the function’s return type. This return technique has the same two restrictions as when returning by reference – the address of a variable must be returned and that returned variable must not be local to the function.

Decltype(3) b = 3; // int&& In C++14, auto may be used as the expression for decltype. The keyword auto is then replaced with the initializing expression, allowing the exact type of the initializer to be deduced. decltype(auto) = 3; // int&& Using auto is often the simpler choice when an initializer is available. Decltype is mainly used to forward function return types, without having to consider whether it is a reference or value type. decltype(5) getFive() { return 5; } // int 43 Chapter 11 ■ Functions C++11 added a trailing return type syntax, which allows a function’s return value to be specified after the parameter list, following the arrow operator (->).

The referencing of array elements can therefore be made just as well with pointer arithmetic. By incrementing the pointer by one you move to the next element in the array, because changes to a pointer’s address are implicitly multiplied by the size of the pointer’s data type. *(p+1) = 10; // p[1] = 10; Array Size Just as with any other pointer, it is possible to exceed the valid range of an array and thereby rewrite some adjacent memory. This should always be avoided since it can lead to unexpected results or crash the program.
