im gunna write everything assuming that you have using namespace std; if you dont then Everytime before vector. you need std:: creation: vector< vector<dataType> > vectorName; ****the space between > > is Extremely important. filling: you can create single(1-D) vectors. vectorName.push_back(vector1D); but there are Lots of ways accessing: just like a 2D array. you can use vectorName [I][j] to access everything. hope this helps!!
