Using a dictionary to count the items in a list [duplicate]

Here, the vector 'v' can be visualised as a two dimensional array, with 'A_NUMBER' of rows, with 'OTHER_NUMBER' of columns with their initial value set to 'DEFAULT_VALUE'.
Also it can be written like this:
std::vector <int> line(OTHER_NUMBER, DEFAULT_VALUE)
