read and store text file as an array

Hello guys,
I have a text file contains values such that the values are stored in the file as matrix of 3 by 4 dimension. i need to read this file and store each column of the matrix in a separate vector or in an array of one dimension.
for example the values in a text file are:

0 8 4 6
-1 7 9 3

Can anyone offer a simple example please.

You can use ifstream for an input file stream.

1. To read an integer from a file stream, you can use extraction operator '>>'
2. To push an element into a vector, you can use vector::push_back method.
