How to manipulate ascii value of letters?
For example, if the ascii value of a and b is 0 and 1, add 1 to the ascii value of a, then the character is changed from a to b.
I know how to do it with array but it is clumsy.
Is there any pre-defined function of certain library to get the ascii value of letters?I searched it and couldn't find any.
Thanks in advance!
