shared_ptr<int[]>holds anint*pointer to the 1st element of anint[]array. That array is expected to be allocated with thenew[]operator (preferably via a call tostd::make_shared<int[]>(size)), and will be freed with thedelete[]operator....
Return a Pointer to a Dynamically Allocated Array in C++ Return a Pointer to a Static Array (Not Recommended) Pass an Array as a Parameter to Modify It Use std::array or std::vector for Flexibility Conclusion Returning a pointer to an array from a function in C++ is a powerful ...
(*(&array+1)-array) :6 *(&array+1) and &array+1 refer to the same memory location. compiler throwing an exception while trying to get the size of the array using a pointer as ((&array+1) - array) what is the difference between ((&array+1)-array) and (*(&array+1)-array)...
I have certain function (in .cpp source) that takes a pointer to an array of 8 integer values. (The function is responsible for creating a Minor - term used in 1553 interface code) I have 4 minors, so I created 2d array: int A[4][8]; I send to the function of Minor1 the para...
But Always Remember Arrays Always started From their index value, and the index of the array starts From 0 to n-1. If we want to Access the 5th Element of the array, we will use the 4th Element Because Arrays are Start From 0, and arrays always stored in Continuous Memory Locations....

wrong, because the OP code relies on the 2 variables being placed in adjacent memory locations. Sure, that is very likely going to happen when the 2 assignments happen on consecutive LOC, but one shouldn't rely on that. It would be a different story if they were 2 items in an array....
