Fill in the int array from zero to defined number

Question

i need to fill in the int[] array in C++ from zero to number defined by variable, but ISO C++ forbids variable length array... How to easily fill in the array? Do i need to allocate/free the memory?

int possibilities[SIZE];
unsigned int i = 0;
for (i = 0; i < SIZE; i++) {
    possibilities[i] = i;
}

btw. if you would ask - Yes, i need exactly standard int[] arrays, no vectors, no maps etc.

Answer 1

In c++11 you can use std::iota and std::array. Example below fills array sized 10 with values from 1 to 10.

std::array<int, 10> a;
std::iota(a.begin(), a.end(), 1);

Edit Naturally std::iota works with vectors as well.
