Howto create combinations of several vectors without hardcoding loops in C++?

Question

I have several data that looks like this:

Vector1_elements = T,C,A
Vector2_elements = C,G,A
Vector3_elements = C,G,T
..... up to ...
VectorK_elements = ...

         


        

Answer 1

This will do the trick:

void printAll(const vector > &allVecs, size_t vecIndex, string strSoFar)
{
    if (vecIndex >= allVecs.size())
    {
        cout << strSoFar << endl;
        return;
    }
    for (size_t i=0; i

Call with:

printAll(allVecs, 0, "");
