Best way to return array in cpp?

[glass ingot]

I want to make a function that creates an new array and returns it

What is the best way to do it?

I could use:

int* createArray(){
int *a = new int[5];
return a;
}

but then I only have a pointer to first element of array and I don't know the size. So I can't iterate through it? Do I need to create a struct to contains pointer to first element and size?

return a std::tuple

unless you’re not using C++

in which case ask #1013104018739974194

why can we create an array in c++ (int a[n]), but not return one?

[lament glen]

because of C++'s C legacy

why not create a std::vector? that should be your default "array" in C++ unless you have some good reason to do otherwise
