Prior to C++17,shared_ptrcouldnotbe used to manage dynamically allocated arrays. By default,shared_ptrwill calldeleteon the managed object when no more references remain to it. However, when you allocate usingnew[]you need to calldelete[], and notdelete, to free the resource. In order to ...
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 ...

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...
constintarray_size=3;intia[array_size]={0,1,2}; If we explicitly specify a list of values, we may not specify the size of the array: the compiler itself will count the number of elements. C++ Pointer A pointer is an object containing the address of another object and allowing indirect...
array anywhere a pointer is expected, and vice versa. A function can handle arrays, but define the type it recieves as a pointer. And since arrays are pointers (constant pointers), they are passed call by reference, meaning the array passed will be modified immediately in the calling ...
