I am using C++

I have a file with three equations involving x, y, and z.

The file looks something like this:

2x+3y-1z=9

5x-0y+3z=4

0z+0y+4z=5

I need to somehow get all 12 numbers from this file and store them into an array. For now I'm just displaying them using cout, so I tried

while(file >> int)

{

cout << int << endl;

}

It's not working; any ideas; please don't just write the entire program for me. Explain what concepts I need to use.
