Hello all,
I'm learning C and I am doing a code review. Now I am looking at a line I have no clue what it's doing... could you guys help me out? It says:
int number = (array[3] - '0') - 1; // array is of the type char * and in the position 3 will have a 1,2,3 or 4.
The part I don't get is the "- '0'" part...
Thank you!
