How to convert ascii to string

Question

Encryption and decryption of string to ascii using addition and subtraction key

Answer 1

Aparna please tag the language in which you need. And also mention your try..
Ex:
If string is "abcde", then
str[0] points to 'a'.
a ascii value is 97.
You get this by casting to int.
(int)str[0]. You can store result in a Integer variable..
(int)str[0]+1 =98
again if you cast this to char will result 'b'.
(int)str[0]+1
This way you add and encrypt values.
Reversing is description.
So this is one way you can do.
Hope this helps you...
