Because of the data structure format and my lack of control over it, this is the only way I see it as possible to parse the data file. WebIn C++, a 2D vector or matrix can be constructed by creating a vector of vectors. To print this matrix, we can iterate over the parent vector using a range based for loop, and then for each of the nested vector, we can again use a range based for loop to print its contents.
