I have a code in which at the end of a function I need to cast from int to double all the elements of an array in order to being able to do a final push_back before exiting the function. The code I have right now is:
template <class T, size_t dims> class A {
typedef typename std::array<int, dims> ArrayInt;
typedef typename std::array<double, dims> ArrayDouble;
typedef typename std::vector <ArrayDouble> VectorDouble;
/* ...*/
foo() {
/* ...*/
ArrayInt myArrayInt;
ArrayDouble myArrayDouble;
VectorDouble myVectorDouble;
/* Initialize myArrayInt
Do some other stuff */
for (int i = 0; i < dims; ++i)
myArrayDouble[i] = static_cast<double>(myArrayInt[i]);
myVectorDouble.push_back(myArrayDouble);
}
}
It works properly, but I do not feel comfortable about the lines:
for (int i = 0; i < dims; ++i)
myArrayDouble[i] = static_cast<double>(myArrayInt[i]);
Is there any better way of doing this?
Thank you.
