How to convert char to integer in C?
c, char, int
Solution
In the old days, when we could assume that most computers used ASCII, we would just do
int i = c[0] - '0';
But in these days of Unicode, it's not a good idea. It was never a good idea if your code had to run on a non-ASCII computer.
Edit: Although it looks hackish, evidently it is guaranteed by the standard to work. Thanks @Earwicker.
