here's a little trick that'll get it done... char x='12'; int y=x-'0'; Now y stores x's value as an integer...

You can also do this: char c1 = '5', c2 = '6' ; int sum = (c1 - '0') + (c2 - '0') ; But Anna's solution is way more easier to implement.

By defining 5 and 6 as integers, not as chars '5' and '6'. Or you can remove the quotation marks: char a = 5, b = 6. Then a will be set to the char with the ASCII value 5 (whatever ASCII char that may be)

(int)char will return the ASCII value of the char, not the number that the char represents. The ASCII value of '5'/'6' is 53/54, their sum is 107 and that's the value that is assigned to a.

Anna that's okay, But my problem is that if those values are stored in a char datatype then what will be the approach?
