Hello,
I have the following text file:
0 1 2 4
5 6 7 8
9 10 11 12
The following code reads the file successfully from start to end:
How should I modify the above code so it would roll back to the begging as soon as it reaches the end of file (essentially reading the same file in an infinite loop) ?
