Solution 2

Give a example.
char ch = '0';
int n = ch - 48;
Than value of n is 0.
48 is the distance in ASCII table.

Why not int n = ch - '0';, which is at least obvious?

Joneeky 18-Sep-12 10:30am

Yes,You also can do this. But I am used to use 48.

Richard MacCutchan 18-Sep-12 10:43am

It's about readability, '0' means something useful to a new person looking at the code, 48 does not.

Joneeky 18-Sep-12 10:48am

Okey,maybe you are right.

Richard MacCutchan 18-Sep-12 11:55am

Well think about it. In the first line of your example you represent the value of the zero character by '0', which is quite clear. In the next line you represent the exact same value by the integer 48, and it is not immediately obvious where that value comes from. Somewhat inconsistent don't you think?

OK, I have learnt.
